Harmful factors of welding materials
(1) The main research object of welding labor hygiene is fusion welding, and among them, the labor hygiene problems of open arc welding are the biggest, and th...
Single-sided welding with double-sided formation is a core technique that welders must master, and it is particularly critical in the welding of pressure vessels and pipelines. It requires the wel...
The thermal conductivity of copper and copper alloys is more than 5 times that of carbon steel. Welding is prone to pores, lack of fusion, and thermal cracks. The selection of welding wire direc...
Tungsten argon arc welding is a kind of arc welding method using argon or argon rich gas as protection and tungsten electrode as electrode, which is referred to as GTAW(Gas Tungsten Arc Weld) or T...
With the rapid development of the petrochemical industry, stainless steel materials have been widely used, which has also put forward higher requirements for the welding of pipes and plates. The pr...
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 ...
