Low Hydrogen Electrodes
AWS/ASME ClassE 7016
SPECIFICATIONSFA 5.1 IS 814 : EB 5324H2X
VJ 7016 is a basic-coated low-hydrogen electrode designed for welding restrained joints subjected to dynamic loading. The weld deposit is of radiographic quality, offering excellent resistance to hot cracking and superior notch toughness at sub-zero temperatures. It is particularly suitable for welding mild steel, medium and high tensile steels, low alloy steels, steel of unknown composition, and for machinable welds on cast iron. This electrode is commonly used in a variety of industries, including boilers, pressure vessels, heat exchangers, oil refineries, and chemical and food industries. It is also well-suited for applications in storage tanks, earthmoving equipment, railways, structural components such as cranes, tractors, rollers, shipbuilding, conveyor systems, and pipelines.
