Welding is one of the most important processes in the metal industry. In order for the weldability of a material to be satisfactory, it is necessary to find the most adequate type of welding and the conditions in which welding will be performed. Weldability of a steel depends about an initial material (chemical composition, microstructure…), filler material and welding process. This paper presents the results of tensile testing of welded austenitic stainless steel S21800. The TIG method was applied for welding and 316L steel was utilized as a filler metal. Welding was carried out on two groups of samples with different chemical compositions. The analysis of the results showed higher values of tensile strength and proof strength in steel with a higher delta ferrite content, but also the presence of a welding defect in the form of incomplete penetration, which affected the reduction of tensile strength compared to the base material.
