Why to choose a laser welding machine?

Laser welding machines have several advantages:

 

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.

They are VERY affordable

  • Fiber laser welding is now with our Lasermach WOBBLE Handheld fiber laser welding machine VERY affordable and accesable for every company

This is why all manufactureres switch to laser Welding:

With laser welding they work faster, cleaner, without deformation and they earn much more money

 

Gas Metal Arc Welding (GMAW) vs Laser Welding

Gas Metal Arc Welding or MIG is a traditional technique using a consumable electrode that works well for larger, badly fitting parts.
  • Laser welding does not use consumable electrodes, requires less edge preparation, is easily automated and is up to 5x faster.
  • Lasers also provide more precision, and lower heat input. 

Gas Tungsten Arc Welding (GTAW) vs Laser Welding

GTAW or TIG uses a non-consumable electrode and provides better process control than GMAW but any filler has to be added separately.
  • Lasers are up to 10x faster with higher precision, lower heat input, and are more easily automated.

Plasma Arc Welding (PAW) vs Laser Welding

Plasma Arc Welding is faster than Gas Tungsten Arc Welding, but much slower than laser welding. Having a large melt pool, PAW is good for badly aligned parts, but creates too much heat for many applications.
  • Lasers offer higher precision, are faster, and have lower heat input in a non-contact process.
  • Laser Wobble Welding is as effective on misaligned parts and does not require daily maintenance of the process head.

Resistance Spot Welding (RSW) vs Laser Welding

RSW is typically used for joining two pieces of material that are stacked on top of each other.
  • lasers only need single-side access, are much faster, and produce higher-strength welds.
  • Lasers do not require electrodes and eliminate the costs and time for electrode replacement.

Electron Beam Welding (EB) vs Laser Welding

Electron Beam welding provides excellent weld quality and a low heat affected zone. Because the process is in a vacuum chamber, contaminant levels are very low.
  • Laser welding speed is similar to electron beam, but because lasers do not require part transfer through a vacuum chamber, laser cycle time is dramatically shorter.
