摘要： 鋼筋焊接采用閃光對(duì)焊，焊接接頭存在一次性抽檢率合格率較低，導(dǎo)致施工中出現(xiàn)返工，既延誤了工期、又浪費(fèi)了人力物力，同時(shí)留下了質(zhì)量隱患。文中從鋼筋閃光對(duì)焊接頭質(zhì)量檢驗(yàn)及驗(yàn)收幾個(gè)方面展開(kāi)論述。

關(guān)鍵詞： 鋼筋閃光對(duì)焊、連續(xù)閃光焊、原因分析及要因確認(rèn)、制定對(duì)策

Abstract： Flash butt welding is used in the welding of steel bars， and the one-time spot inspection rate of the welded joints is low，Lead to rework in the construction， not only delayed the construction period， but also a waste of human and material resources，And left a quality hazard.In this paper， the quality inspection and acceptance of flash butt welding of Steel Bar are discussed.

Key words：  Steel Bar flash butt welding， continuous flash welding， cause analysis and cause confirmation， make countermeasures
