What is Laser Beam Welding?
Laser Beam Welding (LBW) is produced from a beam of high-intensity light which, when focused into a single spot provides a concentrated heat source, allowing narrow welds and fast welding speeds.
There are two main types LBW machines:
- Pulsed Wave (YAG): A pulsed laser can produce peak power greater than its average power. Pulsed lasers are used for spot welding and for seam sealing when heat input is a factor, for example, implantable medical devices or batteries.
- Continuous Wave (CW): CW lasers produce a continuous, uninterrupted beam of light, ideally with a very stable output power. CW lasers are especially suitable for deep penetration welds (over .100” deep), and welding of crack sensitive materials like high carbon alloys.
