The welding residual stress is caused by the uneven temperature distribution of the weldment caused by welding, the thermal expansion and contraction of the weld metal, etc., so the welding constru...
Among welding methods, Tungsten Inert Gas Welding (TIG) and Shielded Metal Arc Welding (SMAW)—commonly referred to as “Arc Welding”—are the two most prevalent processes. Those unfamil...
The energy source of brazing can be chemical reaction heat or indirect heat energy. It uses a metal with a melting point lower than that of the material to be welded as the solder. After heating, t...
There are three types of underwater welding: dry method, wet method and partial dry method.
Dry welding
This is a method in which a large air chamber is used to cover the weldment, and the welder ...
