Illustrate about laser beam welding in short.

Laser beam welding:

Laser beam welding (LBW) is a welding technique utilized to join multiple pieces of metal by the use of a laser. The beam gives a concentrated heat source, permitting for narrow, deep welds and high welding rates. The procedure is frequently used into high volume applications, as like in the automotive industry.

A continuous or pulsed laser beam may be utilized depending on the applications. All milliseconds long pulses are utilized to weld thin materials as like razor blades while continuous laser systems are utilized for deep welds.

LBW is a versatile process, able of welding carbon steels, stainless steel, HSLA steels, titanium and aluminum. Because of high cooling rates, cracking is a concern while welding high-carbon steels. The weld quality is high, same to which of electron beam welding. There speed of welding is proportional to the amount of power supplied although also depends upon the type and thickness of the work pieces.

The high power ability of gas lasers make them particularly suitable for high volume applications. LBW is especially dominant in the automotive industry. Many of the advantages of LBW into comparison to EBW are as given here: the laser beam can be transmitted by air quite than needing a vacuum, the process is simply automated with robotic machinery, x-rays are not produced and LBW result within higher quality welds.
