Title: METHOD FOR LASER BEAM GMA HYBRID WELDING OF HIGH-STRENGTH FINE-GRAINED COMPONENTS USING TARGETED INDUCTIVE HEAT CONDUCTION
Abstract:
The invention relates to a method for laser beam GMA hybrid welding for undetachably joining two or more components made of a high-strength steel, wherein the region around the joining point is inductively heated to 100 °C to 300 °C, preferably a method for defense use, wherein the region around the joining is heated up to 150 °C to a maximum of 200 °C.
