What are the welding methods instead of manual arc welding?

The most commonly used are carbon dioxide gas shielded arc welding and submerged arc welding, while the slower ones are argon tungsten arc welding and laser welding.

Arc welding can be divided into manual arc welding, semi-automatic (arc) welding and automatic (arc) welding. Automatic (arc) welding usually refers to submerged arc welding-covering a protective flux layer on the welding part, inserting a light welding wire made of filled metal into the flux layer, and generating an arc with the welding metal. The arc is buried under the flux layer, and the heat generated by the arc melts the welding wire, flux and base metal to form a weld, and the welding process is automated. The most commonly used is manual arc welding.
