Steel pipe welding line made by Chaochang adopt Germany brand IXYS MOSFET and Fast recovery diode, using 
Induction heating as heating method, water cooling system and PLC control system. Until now we have made many succesful 
for pipe factory customers.

•  

• Application: Used for straight seam welding of carbon steel tube, galvanized pipe, aluminium tube etc. 

Advantages of Steel pipe welding line 
1. Is much more efficient compared with vacuum tube welders.
2. Solid state welders have a compact and modular design.
3. Vacuum tube welders have a lifetime span. Solid state HF welders have semiconductor components, 
    which has no life limit. so high frequency welder is more reliable compared with vacuum tube welders. 

Configuration of Steel pipe welding line 
1. Switch Rectifying Cabinet 
2. Inverter Output Cabinet  
3. Operation Console 
4. Water-Water cooler or Air-Water cooler 
5. 2-D adjustable bracket 
6. Optical fiber
