In view of the shortcomings that the thin plate member has a tendency of welding hot cracking when welding, the new technique of welding with hammering is adopted from the point of view of mechanics, and the purpose of preventing the hot cracking of the sheet welding is achieved by using the testing and testing techniques. New way of hot cracking. The basic principle of preventing hot cracking with welding hammer is discussed. The crack rate of the specimen under normal welding conditions and welding hammering conditions is contrasted. The experimental results show that the weld cracking can effectively prevent the welding hot cracking The production
