Destination of set.

 

The set is destined for demagnetization and compensation of residual magnetic fields while welding of pipelines and other metalwares butts.

 

It has high efficiency for performing of welding works at trunk gas and oil lines.

 

It can be used for demagnetization of parts, constructions and machinery made of ferromagnetic steels.

 

Modes of magnetic fields removing in welding gap are demagnetization and compensation.

 

Gear supplied with set (elastic solenoid) is intended for demagnetization and compensation of con-structions with diameter from 400 mm to 1440 mm and with value of magnetic field induction in welding gap up to 3000 Gs.

 

Operation mode of the complex is set by remote-control board which can work by twin-lead line and radio channel.
