There are two most basic and easily confused types of welding rods in manual arc welding: acidic welding rods (such as AWS E6013) and alkaline low-hydrogen welding rods (such as AWS E7018). Many w...
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 energy source of brazing can be chemical reaction heat or indirect heat energy. It uses a metal with a melting point lower than that of the material to be welded as the solder. After heating, t...
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 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...
First, Welding cracks and pores are generated.
The moisture absorbed by the welding rod becomes gas under the action of the welding arc heat, which decomposes hydrogen, resulting in the formation ...
