This diploma thesis deals with the optimization of process parameters of welding a drainage channel using a laser beam with an additional cold wire. This channel is made of austenitic Cr Ni stainless steel X5CrNi 18-10 (1.4301, ČSN 17 240) with a sheet thickness 1,5 mm. Mechanical properties of samples were checked by using transverse tensile test. Subsequently, the samples were macroscopically inspected focusing on dimensions of the weld and the presence of weld defects. Finally, the structure of the weld metal and fundamental material was evaluated by using microscopic control. Based on evaluation tests, the optimal welding parameters were recommended.
