Arc Welding: The method of using electrode holder to clamp welding electrode, manual arc welding, short hand arc welding.

Gas-Shielded Welding: Gas-shielded welding refers to the welding method of carbon dioxide or argon gas protection, without welding wire for electrode.

Argon arc Welding: Use of industrial tungsten or active tungsten for non-fused electrical grade, inert gas argon as a protective gas welding method.

Referred to as TIG.

1. Hand arc welding uses the stable combustion arc established between the electrode and the work, which melts the welding rod and the workpiece, thus obtaining a firm welded joint.
   

   
   

2. Gas-shielded welding is a high-efficiency welding method to CO2 gas as a protective gas, depending on the arc between the wire and the weldment to melt the metal gas shielded welding method called CO2 welding.This welding method is used wire automatic wire feed, deposited a large amount of metal, high production efficiency, quality and stability.
   

   
   

3. Tungsten Argon arc welding is argon as a protective gas, tungsten electrode as a non-melting pole, with the help of tungsten electrodes and welding between the arc, the heating and melting of the base material (while adding welding wire is also melted) to achieve the welding method. Argon is used to protect weld metal and tungsten electrode molten pool, in the arc heating area is not oxidized by air.
