Abstract [en]

AP Torsmaskiner AB (Smaland, Sweden) is using an LMI laser welding machine equipped with a Trumpf 6 kW CO2 turbolaser and a helium shielding gas for welding car catalytic converters. The LMI system has three axes with two welding stations, with the laser being switched between stations via a moving indexing mirror. The silencer/catalytic converter is produced from W-1.4512 ferritic stainless steel using lap joints. Commissioning problems, including porosity due to dry oil from pressing steel plates, are discussed. Potential system design improvements are mentioned.
