The physical properties and classification of the welding process are achieved through heating or pressure, or a combination of both, with or without filling materials to achieve atomic bonding in the welded part. Welding is a process method for connecting metal materials. The essence of the welding process is to use heating or pressure to firmly connect separated metal materials through the binding and diffusion of metal atoms. The characteristic of welding technology is that welding plays a very important role in modern industrial production. It is particularly advantageous in manufacturing large structures or complex machine parts because it can be used to prepare blanks by reducing size and complexity into simplicity, and then assembled and welded step by step, which is difficult to achieve with other process methods.
