Explanation: HJ331 is a smelting type medium manganese high silicon low gas flux with a particle size of 10-60 mesh, which can be used for both AC and DC. Easy slag removal in the groove, suitable for high current, fast speed (1m/min) welding, good low-temperature toughness and crack resistance.
Usage: Used in conjunction with appropriate welding wires, such as H08MnA and H10Mn2, for welding low carbon steel, low alloy steel, etc., such as shipbuilding, bridges, etc. It can also be used for multi-layer and multi pass welding of pipelines.
Advantages
High production efficiency, high weld quality, manual operation, inherent advantages of stable welding quality, high welding productivity, no arc light and minimal smoke, make it the main welding method in the production of important steel structures such as pressure vessels, pipe sections, and box beams and columns
Application
The product is widely used in marine engineering, nuclear power industry, shipbuilding, boilers, chemical equipment, bridge construction, metal structures, oil pipelines, pressure vessel manufacturing, roll welding, construction industry, etc
