Properties of butt weld joint made on corrosion resistant stainles steel 316 L

The article presents an example of successful welding of stainless steel grade 316 L by using TIG welding process. The welding process influences the melting which starts in consumable material and the most heated base material. It also affects the surrounding material close to the melted material that starts to change its microstructure as a consequence of rapid heating and rapid cooling. The changed microstructure has the influence on mechanical properties and also its corrosion resistance. Mechanical properties obtained at tensile tests, bending, hardness measurements and Charpy tests were studied after the welding on V - shaped butt joint. The microstructure of the base material, heat affected zone and the weld metal was observed and analysed by the light microscope.
