Frequently asked questions

With the handheld laser, the following materials can be welded: steel, stainless steel, aluminium, copper and nickel.

The laser welding machine is supplied with a wire feeder comparable to that of a MIG/MAG machine. Wires on a BS-300 spool can therefore also be used for laser welding.

For manual laser welding, you can use Argon 4.6 or nitrogen. The gas protects the weld pool against oxidation and prevents dust and fumes from entering the welding head.

The laser welding machine emits a laser beam with an invisible wavelength. Direct contact with the laser beam can cause burns. In addition, reflections or direct laser light can cause eye damage. However, highly effective protective glasses are available for this risk. The laser light has no other negative effects.

The fiber of a LAZRZ laser welding machine is 7.5 meters long.

Direct laser light is dangerous to the skin and eyes due to its high energy density. Reflections can also be dangerous to the eyes and may cause eye damage. The light emitted by the laser is not visible, but it behaves like visible light.

No, a standard welding helmet is designed to protect you against visible light and UV radiation. The infrared light from the laser is not blocked by the filter in the welding helmet. However, it is possible to wear a standard welding helmet over laser safety glasses to reduce the brightness of the weld pool.

For laser welding, nitrogen or argon is used. The gas protects the weld pool against oxidation. In addition, the gas flow from the welding torch protects the lenses against welding fumes and dust.

In the LAZRZ FWS series laser welding machines, you can select a welding program based on the material type and thickness.

For laser welding, the following items are required: a laser welding machine, a suitable separated workstation, personal protective equipment, proper knowledge of the machine and its safety risks, and consumable parts for the laser welding machine.

Manual laser welding is not comparable to arc welding processes in terms of the manual skill required. Manual laser welding is easy to perform, and many people can start using this welding process after a short training course.
