Gas Shielded Welding FAQ
What is gas shielded welding?
Gas shielded welding (MIG/GMAW & TIG/GTAW) is an arc welding process that uses an inert gas supply to protect the molten weld pool from atmospheric contamination. It produces the cleanest, strongest welds for industrial applications compared to Stick or Flux-cored methods.
What is the difference between MIG and TIG?
MIG (GMAW) uses a continuously fed wire electrode, making it faster and ideal for high-volume production on thicker materials. TIG (GTAW) uses a non-consumable tungsten electrode and manual filler rod, offering superior precision for thin gauge metals and critical aesthetic welds.
Can gas shielded welding be done outdoors?
Generally, no. Because the process relies on a steady stream of shielding gas (Argon/CO2), even a light breeze can blow the protection away, causing porosity (holes) in the weld. For outdoor field work, Stick (SMAW) or Flux-Cored (FCAW) welding is recommended.
What metals can be welded this way?
These methods are highly versatile. We commonly weld Carbon Steel (using CO2/Argon mix), Stainless Steel (using Tri-mix gases), and Aluminum (using pure Argon). TIG is specifically required for reactive metals like Titanium and Magnesium.
How do you prevent weld distortion?
Heat input causes metal to expand and contract. We manage distortion by using custom fixtures (jigs) to hold parts rigid, optimizing the weld sequence (intermittent welding), and selecting the correct travel speed and amperage to minimize the heat-affected zone (HAZ).
