Reducing distortion by 80-90%
Hybrid laser welding combines a high energy laser beam with conventional arc welding (commonly GMAW) to create an optimal weld pool.

This process can offer operating costs that are reduced by 60-80 per cent, and heat input and distortion that is reduced by 80-90 per cent.

The system can be configured in two ways for different applications: with the GMAW torch leading (for butt welds), or the laser leading (for fillet welds).

Combined with the GMAW process, the laser is able to draw filler metal into the joint to achieve the desired final weld geometry and mechanical properties.

Access to difficult-to-weld parts
In the laser hybrid process, the laser beam and the arc act in the welding zone at the same time, and influence each other. The results are highest possible speed, with the highest possible quality, stabilization of the process, and spatter-free welding, improved gap bridgeability, less distortion and therefore less rework and shorter production times. A newly developed welding head for fully automatic applications has minimum geometrical dimensions, providing easy access to components that are difficult to weld. Steel, galvanized steel and high-grade steels up to a thickness of 4 mm can be welded.

KUKA
Welding 3D workpieces
Hybrid welding with laser and arc brings many benefits for welding applications involving thick-walled materials (construction steel, aluminium, stainless steel, among others). 

With the development of the KS HybridTec, Kuka Systems has succeeded in combining the advantages of traditional arc welding and laser beam welding processes. The compact design allows optimum access to all workpieces, including three dimensional subassemblies.

Precitech
Hybrid welding head
The YH50 hybrid welding head from Precitec is designed for laser GMA hybrid welding for applications such as orbital welding, and welding in shipbuilding, railway car construction and power trains.

The head can be combined with various manufacturers’ GMA systems and features a protective window cartridge and protective window monitoring system. It is equipped with integrated LWM sensors and can be combined with LPF seam tracking systems. Focal lengths are 200 and 250 mm and the total length for the entire system is about 700 mm (with the 200 mm focal length).
