Argon ARC Welding Machine

Argon ARC Welding Machine

1. Description

Argon ARC Welding Machine is using argon gas as a protective medium arc welding method, its characteristic is to use the argon gas in welding area caused a thick and closed gas mask, in order to avoid melting metal outside intrusion and oxidation of the atmosphere.

6. Weld preparation

Thick plate welding in a groove (≥5 mm), welding in the ends of the pipe joint should be performed before 20 - 50 mm range should be remove burrs, water, oil and oxide film, its method has two kinds: mechanical cleaning, use a file or grinder on the surface of the weld. Chemical cleaning; use alcohol to scrub the surface of the welding parts.
