Butt welding electrode for high frequency welding machine, has metallic wire winding helically wound on core, and coiling fillets, in rectilinear support on material to be welded, independently engaged when pressure is excreted on core

摘要

The electrode has a solenoidal metallic wire winding (3) helically wound on a core (2) and screwed at its ends by two screws to two covers. The covers are fixed at a case by four screws and are longitudinally maintained by two extruded strings (5), where the strings are embedded on the length of the case. Each coiling fillet is in rectilinear support on a material (7) to be welded by high frequency and is independently engaged when a pressure is excreted on the core.
