Laser welding machines have several advantages:

They are very fast:

• The laser can heat the metal extremely quickly, while limiting the risk of deformation.
• This technique is particularly effective for welding large amounts of sheet metal, so we can often find it in the automotive industry.

They are also highly accurate:

• 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 weld a variety of parts shapes and materials:

• We usually use laser welding machines are mainly 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, 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.
