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...
Welding is a process in which the materials of the workpieces to be welded (the same or different) are combined by heating or pressure or both, and with or without filling materials, so that the ma...
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...
There are some inherent problems in dissimilar metal welding that hinder its development, such as the composition and performance of the dissimilar metal fusion zone. Most of the damage to the diss...
Among welding methods, Tungsten Inert Gas Welding (TIG) and Shielded Metal Arc Welding (SMAW)—commonly referred to as “Arc Welding”—are the two most prevalent processes. Those unfamil...
Red head thoriated tungsten electrode (WT20)
Currently the most stable and widely used tungsten electrode is mainly used in the welding of carbon steel, stainless steel, silicon copper, copper, br...
