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:

  1. 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.
  2. 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.

Advantages of Laser Beam Welding

LBW is a non-contact process which requires access to the weld zone from only one side of the parts being welded. LBW is frequently used in high volume applications such as automotive and medical device industries. Due to the precise control of parameters and CNC accuracy, our Laser Welders have the capability to repeat any number welds any number of times, repeatable within thousandths of an inch.

Laser Beam Welding at EBI

EBI utilizes both YAG and CW Lasers to weld a wide range of metals, including mild steel, stainless steel, nickel and nickel alloys, titanium, aluminum, copper and copper alloys. The welding of dissimilar metals is also possible between a number of these materials.
