Laser beam welding (LBW)

Is a welding technique used to join multiple pieces of metal through the use of a laser. The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates. The process is frequently used in high volume applications, such as in the automotive industry.The two types of lasers commonly used are solid-state lasers and gas lasers (especially ruby lasers and Nd:YAG lasers).The first type uses one of several solid media, including synthetic ruby and chromium in aluminum oxide, neodymium in glass (Nd:glass), and the most common type, crystal composed of yttrium aluminum garnet doped with neodymium (Nd:YAG).Gas lasers use mixtures of gases like helium, nitrogen, and carbon dioxide (CO2 laser) as a medium.

Regardless of type, however, when the medium is excited, it emits photons and forms the laser beam Is a welding technique used to join multiple pieces of metal through the use of a laser.
