This symbolic representation represents welds ready-made by electric impedance welding, arc welding, and electron irradiation welding on lap joints, excluding fillet welds. For a join weld, extra this representational process social unit by side. If possible, draw the following symbols as specified : for a section weld ; for a seam weld.
