Abstract
Within the technical practice of austenitic stainless steel welding, mostly fusion arc welding processes, or less frequently, high energy density fusion processes are commonly being used. When applying fusion welding process in terms of stainless steel weldability, fabricators face different technological and metallurgical limitations, which are mostly connected to the melting and following crystallization of the weld metal, or excessive heat input resulting into deformation of a weldment. As the MIG brazing process enables a formation of the weld without melting of base material and is also providing relatively low level of heat input to the material, the above-mentioned advantages are subject to research within submitted paper.
The paper is focused on the analysis of MIG brazing application possibilities of joining 304L stainless steel using CuSi3 and CuSi3MnAl types of brazing wire.
