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...
Spot welding is a resistance welding method in which the weldment is assembled into a lap joint and pressed between two electrodes, and the base metal is melted by resistance heat to form a solder ...
In multi-pass and multi-layer welding, temperature control between each bead and layer is crucial. This is the “interpass temperature” under discussion. Interpass temperature refers 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...
Introduction
As the vehicle body is the carrier of other parts of the vehicle, its manufacturing technology directly determines the overall manufacturing quality of the vehicle. Welding is an impor...
As global attention to environmental protection issues continues to increase, all walks of life have begun to seek green and environmentally friendly production methods. The welding industry is no ...
