Vacuum laser welding vs protective gas welding
| Criteria | Laser welding under protective gas (argon) | Vacuum laser welding |
|---|---|---|
| Porosity | ✗Poor | ✓Excellent |
| Oxidation | ✗Poor | ✓Excellent |
| Energy consumption | ✗Poor | ✓Excellent |
| Weld bead homogeneity | ⚠Good | ✓Excellent |
| Mechanical resistance | ⚠Good | ✓Excellent |
| Fatigue resistance | ✗Poor | ✓Excellent |
Laser welding under protective gas (argon)
In many conventional processes, an inert gas (often argon) is used to protect the molten pool from oxidation.
Vacuum laser welding
Conversely, welding performed in a vacuum chamber completely removes air and gases around the joint:
