Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	1. Description of Business Broadwind, Inc. (the “Company”) is a precision manufacturer of structures, equipment and components for clean tech and other specialized applications. The Company provides technologically advanced high value products to customers with complex systems and stringent quality standards that operate in energy, mining and infrastructure sectors, primarily in the United States of America (the “U.S.”). The Company’s most significant presence is within the U.S. wind energy industry, although the Company has increasingly diversified into other industrial markets. Within the U.S. wind energy industry, the Company provides products primarily to turbine manufacturers. The Company also provides precision gearing and heavy fabrications to a broad range of industrial customers for oil and gas (“O&G”), mining, steel and other industrial applications, in addition to supplying components for natural gas turbines. The Company has three reportable operating segments: Heavy Fabrications, Gearing, and Industrial Solutions. Heavy Fabrications The Company provides large, complex and precision fabrications to customers in a broad range of industrial markets. The Company’s most significant presence is within the U.S. wind energy industry, although it has diversified into other industrial markets in order to improve capacity utilization, reduce customer concentrations, and reduce exposure to uncertainty related to governmental policies currently impacting the U.S. wind energy industry. Within the U.S. wind energy industry, the Company provides steel towers and adapters primarily to wind turbine manufacturers. Production facilities, located in Manitowoc, Wisconsin and Abilene, Texas, are situated in close proximity to the primary U.S. domestic wind energy and equipment manufacturing hubs. The two facilities have a combined annual tower production capacity of up to approximately 550 towers (1650 tower sections), sufficient to support turbines generating more than 1,100 MW of power. The Company has expanded its production capabilities and leveraged manufacturing competencies, including welding, lifting capacity and stringent quality practices, into aftermarket and OEM components utilized in surface and underground mining, construction, material handling, O&G and other infrastructure markets. Gearing The Company provides gearing and gearboxes to a broad set of customers in diverse markets including; onshore and offshore O&G fracking and drilling, surface and underground mining, wind energy, steel, material handling and other infrastructure markets. The Company has manufactured loose gearing, gearboxes and systems, and provided heat treat services for aftermarket and OEM applications for nearly a century. The Company uses an integrated manufacturing process, which includes machining and finishing processes in Cicero, Illinois, and heat treatment and gearbox repair in Neville Island, Pennsylvania. Industrial Solutions The Company provides supply chain solutions, light fabrication, inventory management, kitting and assembly services, primarily serving the combined cycle natural gas turbine market. Liquidity The Company meets its short term liquidity needs through cash generated from operations, its available cash balances, through its Credit Facility (as defined and further discussed in Note 9 3 December 31, 2021 December 31, 2020 December 31, 2021 The Company also utilizes supply chain financing arrangements as a component of its funding for working capital, which accelerates receivable collections and helps to better manage cash flow. Under these agreements, the Company has agreed to sell certain of its accounts receivable balances to banking institutions who have agreed to advance amounts equal to the net accounts receivable balances due, less a discount as set forth in the respective agreements. The balances under these agreements are accounted for as sales of accounts receivable, as they are sold without recourse. Cash proceeds from these agreements are reflected as operating activities included in the change in accounts receivable in the Company's consolidated statements of cash flows. Fees incurred in connection with the agreements are recorded as interest expense by the Company.

Significant estimates, among others, include inventory reserves, warranty reserves, impairment of long-lived assets, allowance for doubtful accounts, and valuation allowances on deferred taxes. Although these estimates are based upon management’s best knowledge of current events and actions that the Company may Cash As of December 31, 2021 December 31, 2020 December 31, 2021 2020 Revenue Recognition Revenues are recognized when control of the promised goods or services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Customer deposits, deferred revenue and other receipts are deferred and recognized when the revenue is realized and earned. Cash payments to customers are presumed to be classified as reductions of revenue in the Company’s statement of operations. For many tower sales within the Company’s Heavy Fabrications segment, products are sold under terms included in bill and hold sales arrangements that result in different timing for revenue recognition versus shipment. The Company recognizes revenue under these arrangements only when there is a substantive reason for the agreement, the ordered goods are identified separately as belonging to the customer and not not During 2021 2020, no not not Cost of Sales Cost of sales represents all direct and indirect costs associated with the production of products for sale to customers. These costs include operation, repair and maintenance of equipment, materials, direct and indirect labor and benefit costs, rent and utilities, maintenance, insurance, equipment rentals, freight, and depreciation. Selling, General and Administrative Expenses Selling, general and administrative (“SG&A”) expenses include all corporate and administrative functions such as sales and marketing, legal, human resource management, finance, investor and public relations, information technology and senior management. These functions serve to support the Company’s current and future operations and provide an infrastructure to support future growth. Major expense items in this category include management and staff wages and benefits, share-based compensation and professional services. Accounts Receivable (A/R) The Company generally grants uncollateralized credit to customers on an individual basis based upon the customer’s financial condition and credit history. Credit is typically on net 30 Historically, the Company’s A/R is highly concentrated with a select number of customers. During the year ended December 31, 2021 December 31, 2020 Allowance for Doubtful Accounts Based upon past experience and judgment, the Company establishes an allowance for doubtful accounts with respect to A/R. The Company’s standard allowance estimation methodology considers a number of factors that, based on its collections experience, the Company believes will have an impact on its credit risk and the realizability of its A/R. These factors include individual customer circumstances, history with the Company and other relevant criteria. A/R balances that remain outstanding after the Company has exhausted reasonable collection efforts are written off through a charge to the valuation allowance and a credit to A/R. The Company monitors its collections and write-off experience to assess whether or not may may Inventories Inventories are stated at the lower of cost or net realizable value. Net realizable value is the value that can be realized upon the sale of the inventory less a reasonable estimate of selling costs. Cost is determined either based on the first first Inventories consist of raw materials, work-in-process and finished goods. Raw materials consist of components and parts for general production use. Work-in-process consists of labor and overhead, processing costs, purchased subcomponents and materials purchased for specific customer orders. Finished goods consist of components purchased from third Long-Lived Assets Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization of property and equipment is recognized using the straight-line method over the estimated useful lives of the related assets for financial reporting purposes, and generally using an accelerated method for income tax reporting purposes. Depreciation expense related to property and equipment for the years ended December 31, 2021 2020 not The Company reviews property and equipment and other long-lived assets (“long-lived assets”) for impairment whenever events or circumstances indicate that carrying amounts may not first In evaluating the recoverability of long-lived assets, the Company must make assumptions regarding estimated future cash flows and other factors to determine the fair value of such assets. If the Company’s fair value estimates or related assumptions change in the future, the Company may 7, Leases The Company leases various property and equipment under operating lease arrangements. On January 1, 2019, 2016 02, 842” 2018 11 Warranty Liability The Company provides warranty terms that generally range from one five third December 31, 2021 2020 As of December 31, 2021 2020 Balance, beginning of period $ 33 $ 163 Increase (reduction) of warranty reserve 70 (78 ) Warranty claims 22 (52 ) Balance, end of period $ 125 $ 33 Income Taxes The Company accounts for income taxes based upon an asset and liability approach. Deferred tax assets and liabilities represent the future tax consequences of the differences between the financial statement carrying amounts of assets and liabilities versus the tax basis of assets and liabilities. Under this method, deferred tax assets are recognized for deductible temporary differences, and operating loss and tax credit carryforwards. Deferred tax liabilities are recognized for taxable temporary differences. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not not In connection with the preparation of its consolidated financial statements, the Company is required to estimate its income tax liability for each of the tax jurisdictions in which the Company operates. This process involves estimating the Company’s actual current income tax expense and assessing temporary differences resulting from differing treatment of certain income or expense items for income tax reporting and financial reporting purposes. The Company also recognizes as deferred income tax assets the expected future income tax benefits of net operating loss (“NOL”) carryforwards. In evaluating the realizability of deferred income tax assets associated with NOL carryforwards, the Company considers, among other things, expected future taxable income, the expected timing of the reversals of existing temporary reporting differences and the expected impact of tax planning strategies that may The Company also accounts for the uncertainty in income taxes related to the recognition and measurement of a tax position taken or expected to be taken in an income tax return. The Company follows the applicable pronouncement guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition related to the uncertainty in these income tax positions. Share-Based Compensation The Company grants incentive stock options, restricted stock units (“RSUs”) and/or performance awards (“PSUs”) to certain officers, directors, and employees. The Company accounts for share-based compensation related to these awards based on the estimated fair value of the equity award and recognizes expense ratably over the required vesting term of the award. The expense associated with PSUs is also based on the probability of achieving embedded targets. See Note 14 Net Income Per Share The Company presents both basic and diluted net income (loss) per share. Basic net income (loss) per share is based solely upon the weighted average number of common shares outstanding and excludes any dilutive effects of restricted stock, options, warrants and convertible securities. Diluted net income (loss) per share is based upon the weighted average number of common shares and common-share equivalents outstanding during the year excluding those common-share equivalents where the impact to basic net income (loss) per share would be anti-dilutive.

A performance obligation is a promise in a contract to transfer a distinct product or service to the customer. The Company measures revenue based on the consideration specified in the purchase order and revenue is recognized when the performance obligations are satisfied. If applicable, the transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when or as the customer receives the benefit of the performance obligation. For many tower sales within the Company’s Heavy Fabrications segment, products are sold under terms included in bill and hold sales arrangements that result in different timing for revenue recognition versus shipment.

Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Management’s Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. (“GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the reported period. Significant estimates, among others, include inventory reserves, warranty reserves, impairment of long-lived assets, allowance for doubtful accounts, and valuation allowances on deferred taxes. Although these estimates are based upon management’s best knowledge of current events and actions that the Company may
Cash, Cash Equivalents and Short Term Investments [Policy Text Block]	Cash As of December 31, 2021 December 31, 2020 December 31, 2021 2020
Revenue from Contract with Customer [Policy Text Block]	Revenue Recognition Revenues are recognized when control of the promised goods or services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Customer deposits, deferred revenue and other receipts are deferred and recognized when the revenue is realized and earned. Cash payments to customers are presumed to be classified as reductions of revenue in the Company’s statement of operations. For many tower sales within the Company’s Heavy Fabrications segment, products are sold under terms included in bill and hold sales arrangements that result in different timing for revenue recognition versus shipment. The Company recognizes revenue under these arrangements only when there is a substantive reason for the agreement, the ordered goods are identified separately as belonging to the customer and not not During 2021 2020, no not not
Cost of Goods and Service [Policy Text Block]	Cost of Sales Cost of sales represents all direct and indirect costs associated with the production of products for sale to customers. These costs include operation, repair and maintenance of equipment, materials, direct and indirect labor and benefit costs, rent and utilities, maintenance, insurance, equipment rentals, freight, and depreciation.
Selling, General and Administrative Expenses, Policy [Policy Text Block]	Selling, General and Administrative Expenses Selling, general and administrative (“SG&A”) expenses include all corporate and administrative functions such as sales and marketing, legal, human resource management, finance, investor and public relations, information technology and senior management. These functions serve to support the Company’s current and future operations and provide an infrastructure to support future growth. Major expense items in this category include management and staff wages and benefits, share-based compensation and professional services.
Receivable [Policy Text Block]	Accounts Receivable (A/R) The Company generally grants uncollateralized credit to customers on an individual basis based upon the customer’s financial condition and credit history. Credit is typically on net 30 Historically, the Company’s A/R is highly concentrated with a select number of customers. During the year ended December 31, 2021 December 31, 2020
Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy [Policy Text Block]	Allowance for Doubtful Accounts Based upon past experience and judgment, the Company establishes an allowance for doubtful accounts with respect to A/R. The Company’s standard allowance estimation methodology considers a number of factors that, based on its collections experience, the Company believes will have an impact on its credit risk and the realizability of its A/R. These factors include individual customer circumstances, history with the Company and other relevant criteria. A/R balances that remain outstanding after the Company has exhausted reasonable collection efforts are written off through a charge to the valuation allowance and a credit to A/R. The Company monitors its collections and write-off experience to assess whether or not may may
Inventory, Policy [Policy Text Block]	Inventories Inventories are stated at the lower of cost or net realizable value. Net realizable value is the value that can be realized upon the sale of the inventory less a reasonable estimate of selling costs. Cost is determined either based on the first first Inventories consist of raw materials, work-in-process and finished goods. Raw materials consist of components and parts for general production use. Work-in-process consists of labor and overhead, processing costs, purchased subcomponents and materials purchased for specific customer orders. Finished goods consist of components purchased from third
Property, Plant and Equipment, Policy [Policy Text Block]	Long-Lived Assets Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization of property and equipment is recognized using the straight-line method over the estimated useful lives of the related assets for financial reporting purposes, and generally using an accelerated method for income tax reporting purposes. Depreciation expense related to property and equipment for the years ended December 31, 2021 2020 not The Company reviews property and equipment and other long-lived assets (“long-lived assets”) for impairment whenever events or circumstances indicate that carrying amounts may not first In evaluating the recoverability of long-lived assets, the Company must make assumptions regarding estimated future cash flows and other factors to determine the fair value of such assets. If the Company’s fair value estimates or related assumptions change in the future, the Company may 7,

Standard Product Warranty, Policy [Policy Text Block]	Warranty Liability The Company provides warranty terms that generally range from one five third December 31, 2021 2020 As of December 31, 2021 2020 Balance, beginning of period $ 33 $ 163 Increase (reduction) of warranty reserve 70 (78 ) Warranty claims 22 (52 ) Balance, end of period $ 125 $ 33
Income Tax, Policy [Policy Text Block]	Income Taxes The Company accounts for income taxes based upon an asset and liability approach. Deferred tax assets and liabilities represent the future tax consequences of the differences between the financial statement carrying amounts of assets and liabilities versus the tax basis of assets and liabilities. Under this method, deferred tax assets are recognized for deductible temporary differences, and operating loss and tax credit carryforwards. Deferred tax liabilities are recognized for taxable temporary differences. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not not In connection with the preparation of its consolidated financial statements, the Company is required to estimate its income tax liability for each of the tax jurisdictions in which the Company operates. This process involves estimating the Company’s actual current income tax expense and assessing temporary differences resulting from differing treatment of certain income or expense items for income tax reporting and financial reporting purposes. The Company also recognizes as deferred income tax assets the expected future income tax benefits of net operating loss (“NOL”) carryforwards. In evaluating the realizability of deferred income tax assets associated with NOL carryforwards, the Company considers, among other things, expected future taxable income, the expected timing of the reversals of existing temporary reporting differences and the expected impact of tax planning strategies that may The Company also accounts for the uncertainty in income taxes related to the recognition and measurement of a tax position taken or expected to be taken in an income tax return. The Company follows the applicable pronouncement guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition related to the uncertainty in these income tax positions.
Share-based Payment Arrangement [Policy Text Block]	Share-Based Compensation The Company grants incentive stock options, restricted stock units (“RSUs”) and/or performance awards (“PSUs”) to certain officers, directors, and employees. The Company accounts for share-based compensation related to these awards based on the estimated fair value of the equity award and recognizes expense ratably over the required vesting term of the award. The expense associated with PSUs is also based on the probability of achieving embedded targets. See Note 14
Earnings Per Share, Policy [Policy Text Block]	Net Income Per Share The Company presents both basic and diluted net income (loss) per share. Basic net income (loss) per share is based solely upon the weighted average number of common shares outstanding and excludes any dilutive effects of restricted stock, options, warrants and convertible securities. Diluted net income (loss) per share is based upon the weighted average number of common shares and common-share equivalents outstanding during the year excluding those common-share equivalents where the impact to basic net income (loss) per share would be anti-dilutive.
