…a keyhole surrounded by the melt pool. Vapor pressure within the keyhole
caused by laser beam absorption prevents closure of the melt pool. The focused laser beam
and keyhole continuously move along the welding path.
The quality of a weld is determined by the stability of the keyhole

…wavelength. Then, the center of the beam creates
the keyhole, which is now very stable because of the pre-heating.
The trailing edge of the ring beam sustains the melt pool sufficiently
to allow gas to escape. Because the keyhole is stable and the material doesn't resolidify as fast,…
