Laser welding and arc processes (TIG, MIG) all join metal, but they differ in heat, speed and finish.
Overview — How They Differ
| Laser | TIG | MIG | |
|---|---|---|---|
| Heat-affected zone | Narrow | Medium | Wide |
| Distortion | Minimal | Low–medium | Higher |
| Speed | Fastest | Slow | Medium |
| Finish / grinding | Little/none | Clean, slower | More cleanup |
| Operator skill | ~30 min to learn | High | Medium |
| Best for | Speed, thin metal, appearance | Precision TIG look | High deposition |
Key Specifications & Performance
Laser wins on speed, distortion and finish; TIG still suits some precision aesthetics; MIG suits high deposition on thick steel. For most fabrication, laser cuts labor and rework.
When to Choose Laser
Choose laser for production speed, thin-to-medium metal and clean seams. See how to use a laser welder.
