Spot welding is a resistance welding method in which the weldment is assembled into a lap joint and pressed between two electrodes, and the base metal is melted by resistance heat to form a solder ...
The appearance of the weld matters just as much as its strength. Many of us have been there—the root pass looks great, but when it comes to the cover pass, the weld ends up dark, rough like sandpa...
Shielded Metal Arc Welding (abbreviated as SMAW). The principle is: an arc is generated between the coated electrode and the base metal, and the welding method using the arc heat to melt the electr...
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...
Consider the physical properties, mechanical properties and chemical composition of the weld material
1. Structural steel welding, generally consider the principle of equal strength, choose to me...
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...
