Pyongyang, November 4 (KCNA) -- Pyongyang University of Architecture in the DPRK has developed a new electroslag pressure welding method of great economic value.



The new welding method based on flux made with raw materials abundant in the country makes it possible to save lots of reinforcing bars in construction and shorten the period of construction.



It takes only one minute to butt-weld two bars 32mm in diameter and 30 seconds to join together two bars 16mm in diameter.



The new welding method is highly appreciated by users for speeding up construction, raising its quality and being easy to weld with low power consumption. -0-
