During fusion welding, under the action of the welding heat source, the liquid metal part with a certain geometric shape formed on the weldment by the molten electrode metal and the partially molte...
1.How to weld mild steel?
Low carbon steel has low carbon content and good plasticity, and can be prepared into various forms of joints and components. In the welding process, it is not easy to pr...
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 can use AC or DC welding machine. When using a DC welding machine, there are positive connection and reverse connection. Factors such as the electrode used, the condition of the constructio...
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...
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...
