Description
Moisture resistant hydrogen controlled basic coated electrode for producing tough and ductile weld of radiographic quality in Boilers, Pressure vessels, Medium carbon steels, Cast steel and problematic steels. The weld metal is clean and has low level of impurities, thus having unique properties. The electrode can be used in all conventional positions of welding. It is ideally suited for welding carbon steels used in the construction of equipment subjected to heavy dynamic load, impact and severe service conditions in sour gas service.
