Welding is the core processing technology in the fields of modern manufacturing, steel structures, pipes, sheet metal, auto repair, and special equipment. According to the physical nature of the ...
The welding residual stress is caused by the uneven temperature distribution of the weldment caused by welding, the thermal expansion and contraction of the weld metal, etc., so the welding constru...
E71T-11 and E71T-GS both belong to AWS A5.20 carbon steel self-shielded flux-cored welding wire (FCAW-S). They do not require external shielding gas and are very suitable for outdoor or gasless e...
Selection of welding electrode according to the chemical composition, mechanical properties, anti-cracking performance requirements, at the same time, taking into account the welding structure, ste...
Flux-cored welding wire first appeared in the United States and Germany in the 1920s. However, it was not until the 1950s that it was really widely used in industrial production, especially after t...
Welding current, voltage and welding speed are the main energy parameters that determine weld size.
1. Welding current
When the welding current increases (other conditions remain unchanged), the pe...
