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 position is referred to when welding, the relative spatial position of the weld to the welder.
Figure 1. Tianqiao welding positon
There are flat welding, horizontal welding, vertical ...
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...
Commonly used stainless steel solid welding wires include AWS ER308, ER308L, ER309, ER309L, R316, ER316L and ER2209, etc., which are widely used in stainless steel welding, chemical industry, shi...
The coating plays a complex metallurgical reaction and physical and chemical changes in the welding process, which basically overcomes the problems in the welding of the photo electrode, so the coa...
Electrode arc welding is the most widely used welding method in industrial production. The metal to be welded is one pole, and the electrode is the other pole. When the two poles are close to each ...
