摘　　要：针对NO96薄膜型LNG船殷瓦钢手工焊接部分采用脉冲氩弧焊焊接,焊接效果好,而一般直流氩弧焊机难以做到的问题,介绍不需要脉冲的氩弧焊焊接工艺,通过结合NO96薄膜型LNG模拟舱建造、焊工培训和焊接工艺评定等过程,对殷瓦钢的手工焊接工艺进行探讨,实现了在不使用脉冲的前提下使焊缝达到要求。Usually the manual invar welding of NO96 LNG ship is used by pulse TIG. Using pulse, the welding can get big fusion ratio, small deformation, and hardly burn through, while the general DC TIG is difficult to do this. In light of the NO96 LNG mock-up building, welder training and welding procedure manufacture process, the invar manual welding process was discussed to put forward a TIG technology without pulse, by which the weld can meet the requirement in the premise of not using the pulse.
