Abstract
Butt welding by TIG method using a low alloyed steel wire with solid state transformation point, G3Si1, having 1 mm diameter is a feasible solution for both unique and small series production and for saw blades reshuffling made of dissimilar steels (rapid steel HS 2-10-1-8 for the active part and X32CrMoV4-1 steel for the tool holder).This paper analyses the structural and chemical composition modifications occurred in the heterogeneous welded joints areas by endless saw blades. The phenomena which manage the continuous evolution of the weld chemical composition are highlighted by Energy Dispersive X-Ray Analysis (EDX) and Scanning Electron Microscopy (SEM).
