In this thesis, we presented resistance spot welding and TIG procedure in the field of welding of stainless steels of different thicknesses. We focused on the welding area, where the relevance of this was of key importance. We proceeded from the existing setup, and on the basis of the research we presented the proposed setup. Resistance spot welding was performed on the existing and proposed setup. TIG welding was carried out with the most suitable parameters on the proposed layout. For both processes, we used the metallographic methods to investigate the welding point's suitability. We showed how the new layout could reduce the possibility of errors and at the same time shorten the grinding process, as no extensive material removal is required. On this basis, we could in particular lower the price of the finished product and reduce the number of inadequate final products.
