摘要
为了提高奥氏体不锈钢焊缝金属在深冷低温条件下的冲击韧性，根据若干焊接工艺性试验，讨论了在－ 196℃条件下，碳、氢、铁素体对奥氏体不锈钢焊缝金属低温冲击性能的影响，并且提出了焊材选择的几点建议。
For improving the impact toughness of austenitic stainless steel welding metal in the cryogenic condition,according to the tests of some welding technologies,the effect of carbon, hydrogen and ferrite on austenitic stainless steel impact toughness at 196℃ cryogenic was disuassed and several suggestions for choosing welding metals and technologies were presented.
