Abstract
An apparatus includes a set of pre-welding electrodes including a shape-forming electrode having a contact face. The contact face has a shape-forming structure shaping a cross-section of a first segment of a first wire with a pre-welding shape upon compression of the contact face against the first segment. The pre-welding shape has a reentrance accommodating a second segment of a second wire to be welded to the first wire.
Claims21
An apparatus, comprising:
- a set of pre-welding electrodes including a shape-forming electrode having a contact face, the contact face has a shape-forming structure shaping a cross-section of a first segment of a first wire with a pre-welding shape upon compression of the contact face against the first segment, the pre-welding shape has a reentrance accommodating a second segment of a second wire to be welded to the first wire.
A method of compact embedded-wire welding of electrical wires, comprising:
- forming, via compression, a pre-welding shape on a cross-section of a first segment of a first wire, the pre-welding shape having a reentrance;
- positioning a second segment of a second wire in the reentrance in alignment with the first segment;
- applying an inward pressure on the cross-section to change the pre-welding shape into a welding shape in which a left border and a right border of the reentrance in the pre-welding shape at least partially surround a cross-section of the second segment;
- and
- supplying a welding potential difference between a first position and a second position along a longitudinal direction of the first segment to weld the first segment to the second segment, the cross-section of the first segment has the welding shape at the first position and/or the second position.
