Electric welding is a welding operation that USES welding rods to melt metal parts where they need to be connected by arc at high temperature.Argon arc welding is also known as argon shielded welding, which is to apply argon shielded gas around the arc welding to isolate the air outside the welding area and prevent oxidation in the welding area.

Welding is a common electric welding, argon arc welding is the welding needs to consume oxygen and argon, is through oxidation heating welding.Both require welding rod results are not the same efficiency and effect, the latter is a relatively higher requirements of welding, generally if the steel pipe flange welding will be used.
