In the welding process, there are many matters needing attention. Once neglected, it may be a big mistake. These are the points you must pay attention to if auditing the welding process. If you de...
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...
The welding parameters of electrode arc welding mainly include electrode diameter, welding current, arc voltage, number of welding layers, power source type and polarity, etc.
