The composites with interpenetrating networks have good structure homogeneous and performance; also their mechanics, calorifics and tribology arc excellent.
The procedure and characteristic of the arc discharge,feature of ignitron,firing way,structure features and its application are described in the paper.
It has properties of hardening after malleablization,arc welding and impact resistance.It can grind but can not machining demagnitized steel-bonded carbide.
The system uses PLC procedure control, start-up, forward or backward soldering gun, arc starting, workpiece circumgyration, etc full welding process all can complete automatically.
