Home/Technical Glossary/Tang Welding Tang Welding What is Tang Welding in Motor Core and Commutator Manufacturing? Tang welding is a specialized welding process used in the production of electric motor cores and commutators, where copper winding wires are securely joined to metal tangs  that serve as termination points. It is essential for ensuring strong electrical conductivity and reliable mechanical connections within motors. In commutator production, tang welding connects the armature windings to individual tangs, forming the electrical pathway between the rotor windings and the external circuit. This technique supports the production of durable and high-performance DC motors and universal motors. See examples of tang welding on our Automotive Components page.
