An Introduction to Laser Welding
Laser welding (LW) is a welding process that uses a high-power density laser beam to join two materials together, creating a deep, narrow weld.
How Does Laser Welding Work?
LW is a technique that is known for its versatility and high productivity, especially for thin section materials, and for welding at high speeds.
Compared to other welding techniques, such as MIG and TIG, LW has relatively low heat input overall, resulting in low distortion, excellent mechanical properties, and minimal post-weld machining.
LW with a shielding gas can accommodate any component size, as there is no vacuum chamber. Furthermore, you can use fibre optic delivery systems. This allows the welding head to be remote from the power source.
Machines can be highly automated with high production rates, in addition to there being no waiting time for chamber evacuation. Beam splitting and beam sharing are also possible.
The process presents the following characteristics:
- Deep, narrow weld
- Excellent mechanical properties
- High speed, high productivity
- Low distortion
- Minimal post-weld machining
- Suitable for thin section materials
