Aluminum gives many fabricators their toughest shop challenge. Unlike mild steel, which gives clear visual cues and forgives minor setup errors, aluminum conducts heat rapidly. It also forms a stubborn oxide skin immediately upon exposure to air. When you need high structural integrity, precise penetration, and clean cosmetic beads, Gas Tungsten Arc Welding (GTAW), commonly
Any fabrication shop might have a handful of common factors like a familiar chorus, grinders humming, metal clinking, torches hissing like irritated cats. But somewhere in the corner, contradicting the deafening noise, there’s usually a quieter workstation where the welds look as if they were drawn with a silver-tipped fountain pen. That’s the TIG station.
What Is TIG Welding? TIG Welding (GTAW) is a process where a non-consumable tungsten electrode creates an arc that melts the base metal. The weld area is shielded from atmospheric contamination by an inert gas, typically argon. Unlike MIG welding, TIG doesn’t automatically feed filler metal, instead, the welder manually adds it, giving precise control
