A weld is created at the point of contact, specially formed on the working material. For example, the point of contact (hump) may be bulge or annular or extended technological protrusions. Connecting elements can be done at several points simultaneously. Suitably large electrodes cover all points to be welded in one operation. Overlapping or butt joints are created.
