Abstract
The study addresses the results concerning the autogenous laser welding of T-joint with a butt weld used in the structure of casing panels. The joints were made of 1 and 1,5 mm thick AISI 17-4PH (X5CrNiCuNb16-4) steel. Exemplary welding parameters were determined. The influence of the beam setting in relation to the interface of sheets over joint quality according to PN-EN ISO 13919-1 was investigated. An Actual Test Elements of the Casing with the Stiffening Ribs was welded. Limitations on the use of laser welding tech- nology related to the preparation of welding elements have been specified.
