摘　　要：本文介绍了窄间隙埋弧焊在415mm特厚锻件焊接中的应用,通过工艺试验及工艺评定确定了焊接坡口,并提出了手工焊封底后在不清根的情况下直接采用埋弧自动焊进行焊接的方法,取得良好效果。This article introduces the application of the narrow gap submerged ARC welding in welding the forged piece thick 415mm. The type of groove is determined through procedure tests and procedure qualification. In addition, this article puts forward the welding way that after backing-up with manual ARC welding, the submerged ARC welding is directly operated on the forged piece without backing gouging. The result is good.
