- Hybrid welding, as the combination of laser beam and arc welding, is an innovative joining technology that has many advantages compared to the single processes. With the hybrid process joint gap can overbridges and hence additional and costly joint preparation can be avoided. Also the weld metal composition can be controlled by the filler wire. The laser/MIG hybrid welding pårocess is up to 50 % faster compare to autogenous laser welding. This paper presents results from an ongoing investigation into laser/MIG hybrid welding of 6 mm thick, high strength steels.The results include welding parameters for a 6 kW CO2-laser combined with conventional pulsed MIG/MAG equipment. The influences of the basic MIG parameters as the voltage, pulsing time and pulsing frequency on the welding result were investigated, where especially the geometry of the weld seams as well as undercut formation is considered. The influence of the welding result by adjusting the lateral position of laser beam and MIG arc was also examined as well as suitable parameter setup for different joint configurations like V- and butt joints. In the case of butt joint, the maximum bridgeable gap width was determined.It was found that the MIG power has a major influence at the weld geometry. A high MIG power leads to increased undercut size and increased porosity. The variation of the lateral displacement of the MIG arc was shown to be tolerant. It can be stated that a variation of the lateral displacement of 1.5 mm gave still acceptable welding results. It was possible to weld butt joints with a gap of up to 2.0 mm and a maximum in welding speed was reached with a gap of 1.0 mm.
