Laser welding provides Best Practices for Joining applications

Laser welding is a process of using the metal pieces are connected together. The heat source is a beam that is narrow and deep welds. This type of process is often used in the automotive industry.
Two main types of lasers used in this process: solid and gas. Whichever is used, the result emits photons to form the beam.

solid state

In this process, a solid medium (rather than a fluid) used to generate the spray. This is usually a glass or crystalline material having an element such as neodymium, chromium, erbium or ytterbium is added. The common combination of synthetic ruby ​​and Nd: glass.

Laser welding this process, the operators must wear special glasses to avoid damaging the special screen or the eyes. Some types may operate with pulsed or continuous light, while others just use a pulsed beam. Driving typical weld thin materials such as razor blades. The use of continuous light deeper welding.

Originally, many of these were rod-shaped crystals with flat ends being surrounded by a flash tube containing xenon or krypton. pulse emitted by the flash lasting about two milliseconds. This model is still popular today, but more efficient types such as disc-shaped crystals and diodes have become more widespread.


Using gas mixtures types gases as a medium. Typical gases include helium, nitrogen and carbon dioxide. The high voltage, low current power supplied by the excitation of the gas mixture. This gives a durable medium used in the jet. It can operate continuously or pulsed mode. Because of the added strength of this type they are particularly useful for large volume applications.

Regardless of the method used, the beam must be moved to a welded seam. The conventional type, a person or a robot actually move the laser beam to follow along the seam. Most modern applications, however, use the remote procedure, which moved along the seam of a radiation scanner. This is a much faster and more accurate method.

Laser welding offers a variety of access methods all work. The applied procedure depends on the type of metal and the particular application.
