Abstract
The authors studied the possibility of using the wire arc additive manufacturing (WAAM) technology for creating blanks by gradually depositing layers of three grades of stainless steel using a wire. Metallographic studies, ferromagnetic analysis, tensile and fatigue tests were carried out. It has been established that the chemical composition of the utilized grades of stainless steel has a significant effect on the morphology and degree of development of dendrites formed during the deposition process. The absence of incomplete fusion and other technological defects at the weld bead interface promoted the possibility of using WAAM to create biand tri-metal deposits. The analysis of the fracture surfaces of the samples confirmed the high quality of fusion of various grades of austenitic steels with each other and the uniformity of the deposited metal. The presence of ferromagnetic phases in the samples immediately after the additive process is significantly lower than the calculated values for steel 07Cr25Ni13 and practically reaches the values that are characteristic for this steel after heat treatment.
