Laser Hybrid Welding - The Process
Similar to keyhole welding, hybrid welding sees a laser beam be used to achieve a sufficient welding depth, especially for high material thicknesses. Since seam preparation is often not carried out in an ideal fashion for particularly thick sheet metal, resulting in larger gaps, the missing material must be filled in with an additional wire. To this end, laser hybrid welding combines laser welding with the MIG/MAG welding process. The filler material fills the laser beam funnel and optimizes the flank connection. Both processes work within one process zone, enabling the advantages of both processes to be utilized.
Process advantages of laser hybrid welding
By combining the advantages of both processes, laser hybrid welding enables high welding depths with high gap bridging to be brought together simultaneously, especially for high material thicknesses. The filler material enables the properties of the weld seam to be positively influenced, too.
