Beschreibung
Zusammenfassung:	A method and apparatus is disclosed for induction heating weldable surfaces and moving the heated surfaces together with sufficient force to upset the surfaces while in a substantially inert atmosphere for thereby welding the surfaces together. The apparatus includes a rotary bus bar joint for moving the induction coil between the weldable surfaces, and also includes a clamping mechanism for handling members having weldable surfaces of different sizes and shapes. A pair of separately controlled induction coils may be used with or without laminations for heating tubular or solid members to an upsetting temperature.
