Fast axial flow gas lasers are available between _____ watts power levels.

Laser welding is a technique that uses a focused beam of light to join pieces of metal or thermoplastics. The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates.  Laser welding works by generating laser light and then delivering it to a collimator/optics head. The laser beam provides a concentrated heat source, focused to the cavity between the two metal pieces to be joined.  Laser welding was first demonstrated for thermoplastics in the 1970s, and since the late 1990s it has been used in mass production.  The choice of laser type depends on...

Laser welding works by generating laser light and then delivering it to a collimator/optics head. The laser beam provides a concentrated heat source, focused to the cavity between the two metal pieces to be joined. 
Laser welding was first demonstrated for thermoplastics in the 1970s, and since the late 1990s it has been used in mass production. 
The choice of laser type depends on cost, the type and thickness of material to be welded and the required speed and penetration.
