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...
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 rainy season presents unique challenges for welding operations. High humidity, condensation, and moisture ingress are not just discomforts—they are direct threats to weld integrity. Moisture ...
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...
“Verified Market Report” recently released a report on the arc welding electrode market. The report provides the overall scope of the market, including future supply and demand, emergin...
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 ...
