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...
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...
