摘要
Abstract
In order to improve the welding quality of the 200 mm thickness GS30Mn5 special material driving shaft and the matching degree of the welded joint and base metal,the submerged arc welding test and welding procedure qualification for GS30Mn5 steel were carried out. The results indicated that the welded joint tensile,bending,impact,Vickers hardness test results and macroscopic examination all meet the requirements of EN15614-1. According to the research,choosing the appropriate welding material and welding process and controlling the heat input strictly can obtain the good welded joint, achieve a good match with the strength of base metal and reduce the welding cracking tendency. The welding process instructor of this test was used to guide the welding production in the workshop and obtained good effect.关键词
