1. Core principle: Why must we use argon?
During the welding process, the metal is like red-hot iron at high temperatures. If it is not protected, it will immediately combine with the oxygen and ...
Argon tungsten arc welding uses argon as a shielding gas to heat and melt the welding material itself (it is also melted when the filler metal is added) by means of the arc generated between the tu...
The weldability of metal materials refers to the ability of metal materials to obtain excellent welding joints using certain welding processes, including welding methods, welding materials, weldin...
Knowledge point 1: Influencing factors and countermeasures of welding process quality
Process quality refers to the degree of guarantee of product quality in the process of production. In other wor...
When welding stainless steel, the performance of the electrode must match the purpose of the stainless steel. Stainless steel electrode must be selected according to the base metal and working cond...
Important structures such as boilers and pressure vessels require safe penetration of joints, but due to limitations in structure size and shape, double-sided welding is sometimes impossible. A sp...
