Research on the welding process of 316L stainless steel medium thick plate for nuclear power
A nuclear power vacuum chamber project is mainly made of 316L stainless steel material.According to the structural characteristics of the project parts.The manufacturing process of the project involves a large number of welds that require single-sided welding and double-sided formation,and all welds require full penetration and the weld permeability is less than or equal to 1.03H/m,and the overall contour is±3mm,so the manufacturing is very difficult.Based on the above situation,decided to carry out special scientific research projects and research,and finally decided to adopt the laser welding(base)+TIG welding(filling)welding method,adopt the combination of theoretical analysis and test.By conducting the corresponding welding process research on the 40mm medium thick plate,ensure that the welding method and process fully meet the needs of the actual engineering equipment,and make full preparations for the promotion of the project.
