Laser Welding
Gas or solid state lasers may be used
- Gas lasers
- continuous operation
- laser gas; helium+CO2+N2 mixture
- 0.3 to 25kW
- Wavelength 10.6mm
- Solid State Lasers
- Pulsed operation - produces joints similar to spot welds but with complete penetration
- Pulse energy 1 to 100 Joules
- Pulse time 1 to 10 milliseconds
Fast process, heat input and distortion are low
