In GMAW (gas metal arc welding) practice, vertical welding is a real challenge for many welders. If you’re not careful, the molten metal drips down, the weld bead looks like a bunch of berr...
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...
“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 ...
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...
There is no difference in process between full argon arc welding and argon arc welding. Full argon arc welding is suitable for thin-walled small-diameter pipes (generally DN60 and below, wall thick...
