New Kind of Welder Developed in DPRK
Pyongyang, January 23 (KCNA) -- A new kind of mobile rail butt-welding machine was developed by the Railroad Construction Institute of the Branch Academy of Railway Science under the State Academy of Sciences in the DPRK.

In the existing methods, rail butt-welding needs a great deal of power consumption as it is based on the contact electric resistance welding.

But the newly developed welding machine depends on spark discharge welding, thus preventing oxidation of weld zone and increasing the welding quality with lower power consumption.

It can be used for butt-welding any kinds of rails.

The welding machine is well received by users for its serviceability.
