Abstract
Through dissimilar materials welding performance analysis of the alloy steel 42CrMo and ZG270-500,determine the preheating temperature,post weld heat treatment temperature and other welding process parameters,strictly control the welding sequence and the removal of hardening layer,the welding seam is insulated by the method of flame heating,and the training and technical disclosure of welding operator and quality control personnel are carried out to ensure the welding quality of dissimilar materials with poor weldability.关键词
