High Frequency Solid State Induction Welder

Solid state high frequency welding pipe equipment's Solid state high frequency welding pipe equipment uses the common structure of frequency conversion such as AC-DC-AC. Three phase 380V power supply is sent to step down transformer before it passes through switch cabinet. The AC power supply is around 200V which has been dropped voltage to sent into the rectifier in rectifier cabinet, Rectifier use thress phase thyristor fully controlled bridge rectifier, through control thyristor breakover time delay angle a to achieve the purpose for adjustment output power size.
The rectified DC voltage is sent to the high frequency invertor before pass through the filter link. high frequency invertor to inverter producing single phase high frequency and being send to resonance circuit. Via the matching of load and the adjusting mechanism output high frequency energy to complete steel pipe welding. The comparison with vacuum tube high frequeny, the main diffrence between vaccume tube welder is it's efficiency SSW efficiency is 85% as campair to vaccum tube welder which is 65% and SSW no oscillator valve i s used solid state welder save electricity consumption because off it's 25% efficiency saving.
