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...
In the welding process, there are many matters needing attention. Once neglected, it may be a big mistake. These are the points you must pay attention to if auditing the welding process. If you de...
The welding electrodes that leave the factory have been dried at high temperature and packaged with moisture-proof material, which usually prevents the coating from absorbing moisture. However, dur...

1. Structural steel welding, generally consider the principle of equal strength, choose to me...
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...
I. What is welding arc blow?
Welding arc blow refers to the phenomenon that the arc deviates from the original axis direction of the electrode or electrode during the welding process, which wi...
