In the past years laser welding has been established as an efficient joining technology in manufacturing. It offers wide application possibilities with regard to the welding materials as well as the variety of parts and loading conditions. Driven by requirements to manufacture at lower costs and higher efficiency speed and reliably there is an increased industrial need for refined welding solutions. IWS is especially focusing on the component- and material-adapted process development. In combination with a range of laser sources new applications can be explored for example the joining of high strength or hard-to-weld materials and the role of laser welding in lightweight component designs. Process development is concentrated on the laser welding of steel with high carbon content (e. g. heat treatable spring and tool steel) and of other hard-to-weld materials (e. g. free machining steel hot crack sensitive austenitic steel cast iron). Laser induction welding as well as other hybrid processes are avaivable for the efficient material and load-adapted joining especially for lightweight constructions (e. g. Al Ti Mg alloys). Process diagnosis and material testing guarantees high process stability and production quality. Processes Variants: Laser beam deep-welding with CO2 and Nd:YAG-lasers (Power range: CO2: 2 0 - 20 kW; Nd:YAG: 0 8 - 3 0 kW); Heat conduction welding with high power diode lasers (HLDL to 2 5 kW); Laser beam welding with additional wire; Induction assisted laser welding (induction generators: 4-20 kHz power up to 80 kW); TIG assisted laser welding (choices are: CO2 or Nd:YAG-laser); Plasma assisted laser welding (CO2 or Nd:YAG-laser); MIG assisted laser welding (CO2 or Nd:YAG-laser); HLDL assisted laser welding (CO2 or Nd:YAG-laser).
