Joining high current carrying copper wires and leads for electric batteries and motors can be accomplished using either arc or resistance welding methods. Resistance methods have the advantage of faster cycle times but traditionally have been difficult to welds since the wires are generally made from commercially pure copper.
May 27, 2019· Traction pulls the skin that lies on or near the affected bone, manipulating soft tissue and pulling the bone into a fixed, rigid position. This forces the bone to stay in the corrective spot. Skin traction should only be applied by a team of medical professionals, following a formal diagnosis and skin traction prescription.
