摘要：
Lack of penetration at the joint of the main and filler metals as well as at adjoining weld beads can be a significant disadvantage in restoring worn parts by electrocontact welding when wires are welded in the helical curve. The best way to improve restoration quality is to find a better welding condition. It is possible to meet a lack of penetration by additional force impact on welding material by stretching the wire at welding. A new way to two filler wires simultaneously by stretching them with different forces is recommended. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
