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 can use AC or DC welding machine. When using a DC welding machine, there are positive connection and reverse connection. Factors such as the electrode used, the condition of the constructio...
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...
Welding work involves many industrial fields, welding fume is one of the most common hazards of welding work.
Welding fume is in the welding process when the welding rod and welding parts in contac...
Tungsten argon arc welding is a kind of arc welding method using argon or argon rich gas as protection and tungsten electrode as electrode, which is referred to as GTAW(Gas Tungsten Arc Weld) or T...
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...
