ABSTRACT:
A contoured welding rod forms a stringer bead to couple the adjacent bevelled end surfaces of an aligned pair of metal pipes or metal sheets. The welding rod is fabricated from an uncoated alloy metal and has an upper section which includes symmetrical side surfaces inclined at an angle equal to the angle of inclination of the bevelled end surfaces of the pipes or sheets. The rod also includes a lower section which is coupled to the lower portion of the upper section and is dimensioned to penetrate through the gap between the adjacent bevelled end surfaces of the pipes or sheets. During the welding operation the upper section of the rod joins the bevelled surfaces of the pipes or sheets, while the lower section of the rod joins the surfaces of the pipes or sheets on the opposite side of the gap between the pipes or sheets.
