“Welding” includes many different processes and systems.
MIG (Metal Inert Gas) welding involves the use of spools and MIG welding guns. This welding process is very good for both steel ...
Welding current, voltage and welding speed are the main energy parameters that determine weld size.
1. Welding current
When the welding current increases (other conditions remain unchanged), the pe...
During fusion welding, under the action of the welding heat source, the liquid metal part with a certain geometric shape formed on the weldment by the molten electrode metal and the partially molte...
1. What is the purpose of steel annealing?
Answer: ①Reduce the hardness of steel and improve plasticity, so as to facilitate cutting and cold deformation processing; ②Refine the grain, uniform the ...
