acquiring a hull origin coordinate of the hull welding line unit;
searching a welding seam which is a vertical angle section in at least one section welding seam contained in the ship body welding seam unit in a clockwise direction from the original point coordinate as a starting point, and acquiring an interchange welding seam coordinate of the vertical angle section welding seam;
and connecting the overpass weld coordinates to form a vertical fillet welding track.
