• They are very fast:
  • The laser allows the metal to be heated extremely quickly, while limiting the risk of deformation.
  • This technology is particularly effective for welding large quantities of sheet metal and is therefore widely used in the automotive industry.
• They are also highly accurate:
  • They allow a localized, very fine, very clean, almost invisible welding.
  • They are particularly suitable for welding small parts.
  • This type of welding is very popular in the dental and jewellery industries as it provides the most aesthetic welding possible.
  • It is also possible to split the laser beam into several beams to provide welding that is even more accurate.
• They can be adapted to a wide variety of part shapes and materials:
  • Laser welding machines are mainly used to weld metals, including refractory metals.
  • It is also possible to weld non-metallic parts with them, such as porcelain and glass.
  • You can use them to weld parts with very different shapes.
• They do not wear out:
  • Laser welding machines operate without contact, so there is no risk of wear and tear on the machine.
  • There is also no need to change tools or electrodes, which is a definite advantage in terms of waste reduction.
• They can be given orders digitally:
  • It is now possible to control the quality of the welding from a computer during the welding process.
  • The high level of automation allowed by such a process also makes it possible to detect and solve any quality problems.

However, it should be noted that laser welding machines also have certain disadvantages:

• The costs of installing laser equipment are still very high.
• This technology requires high assembly accuracy during processing to avoid laser beam deflections on the parts.
• The laser weld is thinner than that obtained with electron beams, making the process unsuitable for welding high reflective metal.
