Short answer: TIG welding uses a non-consumable tungsten electrode for precise, clean welds on thin and exotic metals; MIG feeds a consumable wire for fast, high-deposition work on thicker sections — the choice is speed versus finish and control.

Process Differences
TIG holds a separate filler by hand and shields with argon; MIG pushes wire through the gun. Background in How To Weld Stainless Steel, Como soldar alumínio e How To Weld Carbon Steel; joint prep in Weld Edge Prep Guide.
Picking the Process
Use TIG for thin sheet, root passes and colour-critical work; use MIG for long seams and thick plate. Avoid mixing metals via Dissimilar Metal Welding Guide and control heat with Metal Heat Affected Zone Guide.
QA & Supply
Check beads and cracks by Weld Defects Guide e Metal Ndt Guide, limit distortion (Metal Welding Distortion Guide), and document consumables per Welding Consumables Guide e Mill Test Certificate Guide. HXSCO supplies weld-ready plate and tube.

Perguntas frequentes
TIG uses a fixed tungsten electrode with hand-fed filler; MIG feeds a consumable wire automatically.
TIG — its lower, controllable heat avoids burn-through on thin metal.
MIG — the continuous wire feed gives much higher deposition rates.
Yes — it needs both hands and precise heat control, so it takes more skill.
