SUB-PROCESS 07 — CNC Sheet Metal
MIG Welding
Automated MIG (Metal Inert Gas / GMAW) cells deliver consistent, high-speed welds for production enclosures and brackets. MIG deposits 2–3× faster than TIG with excellent fusion depth, making it the process of choice for structural joints on carbon steel, stainless, and aluminum. We achieve continuous fluid-tight seams that enable IP65-rated enclosures, backed by X-ray inspection on critical assemblies.

MIG vs Other Welding Methods
Multi-parameter comparison to help you choose the right joining method for your application.
| Parameter | MIG (GMAW) | TIG (GTAW) | Spot (RSW) | Laser |
|---|---|---|---|---|
| Welding Speed | Moderate — 1000–3000 mm/min | Slow — manual pace, 50–300 mm/min | Very fast — 0.1–0.5 s/spot | Very fast — 10–5000 mm/min |
| HAZ Width | Moderate — 3–5 mm | Narrow — 1–2 mm | Very narrow — <1 mm | Ultra-narrow — <1 mm |
| Distortion | Moderate | Low | Very low | Minimal |
| Filler Material | Required | Optional | None | None |
| Automation | Semi-auto / auto | Manual / semi-auto | Fully automated | Fully automated |
| Appearance | Good — minor ripples | Excellent — smooth stacked-dime bead | Limited — spot marks only | Excellent — cosmetic seam |
| Best For | High-speed structural welds | Food-grade, sanitary, visible joints | High-volume sheet assemblies | Precision enclosures, thin-wall parts |
