Abstract

The mechanical properties of electron beam (EB) welded joints of various stainless steel sheets were investigated in comparison with those of TIG arc welded joints, especially from the view point of draw and formability.<BR>The main results obtained are as follows.<BR>1) The width of weld bead at the center of thickness is about 0.5 mm in EB welding and is about 4 mm in TIG arc welding. The grain growth in TIG arc weld bead is more remarkable than in EB weld bead in the cases of ferritic stainless steels.<BR>2) The draw and formability of EB welded joint are the same as those of base metal and superior to those of TIG arc welded joint.<BR>3) When the width of EB weld bead is on purpose widened, its proprties are deteriorated on the equal level of TIG arc welded joint.<BR>4) From 1)-3) etc, the reason why the properties of EB welded joint are better than those of arc welded may be attributed to the narrow width of EB weld bead. The change of properties of this weld bead is not revealed by the restraint of the base metal.
