Description

Jaws holding parts to be welded are pneumatically and hydraulically controlled: First part of the cycle removes oxides and equalizes surface condition by passing pre-heat current(parts may be oscillation) Second part of the cycle upsets the parts with a great force, squeezing imperfect metal outside of the joint, creating very strong bond: This equipment is used to weld wide range of parts from automotive rims to knife and spoon handles. Features Pre-heat, flashing and forces are controlled by combination of electro-mechanical, pneumatic and hydraulic, devices for precise control of the process: Microprocessor control and multi-tap arrangement in transformers allows selecying precise parameters for welding various parts. Both types of machines are used in drums, can making along with automotive and other applications:
