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...
1. What is arc striking? What are the ways to start an arc? What should you pay attention to when striking an arc?
The process of igniting and producing a stable arc is called arc ignition. There...
Vertical welding with stick electrodes gives many welders trouble. The molten metal wants to drip downward, the puddle sags, and the bead ends up uneven. But vertical welding is not as hard as it...
Stick Welding Process Intro
SMAW (Shielded Metal Arc Welding) is often called stick welding. It is one of the most popular welding processes used today. Its popularity is due to the versatility...
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...
Among welding methods, Tungsten Inert Gas Welding (TIG) and Shielded Metal Arc Welding (SMAW)—commonly referred to as “Arc Welding”—are the two most prevalent processes. Those unfamil...
