How Handheld Laser Welding Works
Laser light from the source is transmitted through an optical fiber to the handheld welding head, where it is focused onto the workpiece surface. The laser energy is absorbed and converted to heat, melting the material or filler wire. Shielding gas protects the molten pool, forming a high-quality weld that securely joins the two pieces.
The water chiller cools and maintains constant temperature for both the laser source and welding head to protect critical components.
FAQ
Does it require 380V three-phase power?
Yes. The 3000W model has high power consumption and requires 380V three-phase for stable operation. 220V cannot meet the power demand.
What are the advantages over TIG welding?
| Comparison | TIG Welding | Handheld Laser Welding |
|---|---|---|
| Welding Speed | Slow | 3–10× TIG speed |
| Heat-Affected Zone | Large | Small |
| Distortion | Prone | Minimal or none |
| Weld Appearance | Rough, needs polishing | Smooth, consistent |
| Seal Integrity | Porous, prone to leakage | Perfect seal |
| Operator Skill | Needs skilled, certified | 0 experience, 1 day training |
What is the warranty period?
- 12 months full machine warranty from delivery date
- 24 months on laser source and core components
- 3 months on consumables (lenses, nozzles, wire feed wheels)
