Harmful factors of welding materials
(1) The main research object of welding labor hygiene is fusion welding, and among them, the labor hygiene problems of open arc welding are the biggest, and th...
What is flux-cored arc welding?
Flux-cored wire arc welding is a welding method that uses the arc between flux-cored wire and workpiece to heat, and its English name is simply FCAW. Under the actio...
The so-called welding skills are simple welding methods, correct electrode angle and operation, and your welds will not be too bad.
At the beginning of welding, due to the lack of mastery of the we...
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...
Shielded Metal Arc Welding (abbreviated as SMAW). The principle is: an arc is generated between the coated electrode and the base metal, and the welding method using the arc heat to melt the electr...
The welding position is referred to when welding, the relative spatial position of the weld to the welder.
