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...
Welding electrodes are metal wires with baked on chemical coatings. The rod is used to sustain the welding arc and to provide the filler metal required for the joint to be welded. The coating prote...

1.1 Selection of tungsten argon arc welding machine and power polarity
TIG can be divided into DC and AC pulses. DC pulse TIG is mainly used f...
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...
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...
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...
