904L全奥氏体不锈钢的焊接问题研究

Study on Welding of 904L Austenite Stainless Steel

对904L不锈钢进行了成分、性能分析和焊接性试验,确定了适宜的焊接方法和焊材的选用,并精心编制了其焊接工艺。将此应用于904L全奥氏体不锈钢压力容器的制造过程中,取得了满意的效果。

By the analysis of the composition, property and the weldability test of 904L stainless steel, the appropriate welding operation and welding material were determined. The welding process was studied, which is applied to the manufacture pressure vessel of 904L austenite stainless steel. It achieves satisfactory results.
