Explanation: HJ257Z is a smelting type low manganese silicon gas flux, which is a brown or black glassy particle with a particle size of 2.5-0.45mm (8-40 mesh). Using DC power welding wire to connect the positive electrode, the welding process has good performance, and the thick plate with narrow gap is easy to remove slag, resulting in a beautiful shape. Purpose: In conjunction with pure iron welding wire, it can weld pure iron structures. Such as galvanized pots, galvanizing, etc.
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
