Summary: The master thesis deals with the evaluation of the influence of laser beam offset on the microstructure and mechanical properties of dissimilar metals weld joints. Oxygen free copper C 10600 and austenitic stainless steel AISI 304, with the thickness of 1 mm are proposed as experimental materials. Weld joint consisting of mentioned materials combination, offers high electrical and thermal conductivities and superior corrosion resistance. Thus, dissimilar metals joints are utilized in various fields of industry such as power generation, nuclear and heat exchanger. Design of experiment (DoE) will be used to evaluate the influence of welding parameters on geometry and mechanical properties of weld joints and optimization of welding parameters as well. Furthermore, light microscopy, scanning electron microscopy and microhardness measurements will be used to analyse the weld joint properties. It is assumed that differences in laser beam offset will result in various intermixing of both metals.
