摘　　要：介绍窄间隙埋弧焊在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。Application of narrow gas submerged ARC welding to forging 415mm thick is introduced. Groove type is determined through procedure tests and procedure qualification. In addition, good results have been obtained by directly using submerged ARC welding without back gouging after backing-up with manual ARC welding.
