Electron beam additive manufacturing (EBAM) process with a deposited material in the form of a wire is an efficient method enabling the making of component parts. The scope of the presented work was to investigate the influence of selected technological parameters of EBAM such as: wire feed rate, beam current, travelling speed, acceleration voltage on stability of the deposition process and geometric dimensions of the padding welds. The achieved results and gained knowledge allowed for the production of a whole structure from stainless steel. The macrostructure, microstructure and hardness profiles of final additive manufacturing parts are also presented.
