The purpose of this paper is to analyze weld joints made with the use of the CMT method. Two separate kinds of weld joints were used: one joining two pieces of titanium and another joining titanium with stainless steel. The theoretical part of this paper summarizes the basics of the CMT welding method and its modifications, the corrosion of metals, the tests used to determine the properties of the materials, the preparation of the metallographic cut and more detailed information on the materials used. The experimental part of this paper follows, dealing with precise specifications of the welding process, the materials and the conditions under which the subsequent tests were taken. Half of the samples undertook test in a salt corrosion chamber in order to determine the damage caused to the weld by the corrosion and to compare the results with the samples not exposed to the increased corrosive environment. Following that comes the evaluation part, where the results obtained from the tests undertaken are analyzed with the focus on the resulting formed, the strength test and the hardness of the weld and its surroundings.
