The short time tensile strengths of the butt welded mild steel and 18/8 austenitic steel, compared with the unwelded base metal, are tested at a certain temperature up to 925°C. At every temperature the welded parts indicate no much difference from the base metals in tensile strengths, but elongation percentage and reduction of area of the welded parts are far less than those of base metals. From this phenomena it is surmised that gasses and carbon absorbed in deposite during welding process combine with Fe and Cr etc. and intercrystalline weakness is associated with these compounds.
