N2 - An edge joint 2+2 mm thickness of ordinary austenitic stainless steel sheets was studied in all-position laser welding; flat (PA), vertical-up (PF), vertical-down (PG) and overhead (PE) positions. The penetration depth of the weld was aimed to be at minimum 3.0 mm. The optimal width of the weld was around 2 mm to guarantee adequate tolerances for the weld, but to avoid excessive melting of the edges of the sheets. In addition, the tolerance for the misalignment of the laser beam was tested. The welding procedure was tested with three laser welding methods, including de-focused laser beam, laser beam scanning and twin-spot laser beam welding in order to develop and find means to deploy laser welding robustly and reliably in practical applications. According to the results of welding test trials, the used configuration of twin-spot process seemed to be the most appropriate one among the tested welding methods to guarantee all position welding capability with constant suitable width and depth of weld penetration.
