摘　　要：介绍了纯镍的手工钨极氩弧焊和埋弧焊的试验以及应用于生产实践中的情况,论述了埋弧焊与手工焊相比所独具的高效、低耗、节能等显著优点和为防止焊接裂纹及气孔所采用的工艺措施,并提出了对工程中出现问题的解决方法。In this paper, the test of manual argon tungsten and submerged - arc welding in pure nickel and the status used in productive practice. This articl illustrated the significant merit of submerged - arc welding （such as high activity, low loss, energy saving etc） contrast to manual welding, as well as the procedure for prevent welding crack and blowhole. The countermeasure for problem appeared during application was.
