Welders do not necessarily know the characteristics of the welding heat process
During the welding process, the metal to be welded undergoes heating, melting (or reaching a thermoplastic state) and subsequent solidification and continuous cooling due to heat input and transmission, which is called the welding heat process. The welding heat process runs through the entire wel...Read more -
Fusion welding, bonding and brazing – three types of welding give you a comprehensive understanding of the welding process
Welding, also known as welding or welding, is a manufacturing process and technology that uses heat, high temperature or high pressure to join metal or other thermoplastic materials such as plastics. According to the state of the metal in the welding process and the characteristics of the process...Read more -
Welding Tips -What are the steps of hydrogen removal treatment
Dehydrogenation treatment, also known as dehydrogenation heat treatment, or post-weld heat treatment. The purpose of post-heat treatment of the weld area immediately after welding is to reduce the hardness of the weld zone, or to remove harmful substances such as hydrogen in the weld zone. In thi...Read more -
Four Key Points for Improving the Technical Level of Pressure Vessel Welding Operation
Important structures such as boilers and pressure vessels require joints to be welded safely, but due to structural size and shape constraints, double-sided welding is sometimes not possible. The special operation method of single-sided groove can only be single-sided welding and double-sided for...Read more -
