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...
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...
Welding defects can be divided into two main categories based on their location in the weld: internal defects and external defects.
External defects are located on the outer surface of the weld an...
