Explanation: HJ250G is a smelting type low manganese silicon fluorine flux. It is a light yellow to light green jade like particle with a particle size of 2.0-0.45mm (10-40 mesh). Using a DC power supply and welding wire connected to the positive electrode, the welding process has good performance, easy slag removal, and beautiful forming.
Usage: Suitable welding wires, such as H08MnMoA, H08Mn2MoA, H08Mn2MoVA, can be used to weld low-alloy high-strength steels, such as 15MnV, 14MnMoV, 18MnMoNb, etc. Cooperating with H08Mn2MoVA welding wire to weld 09Mn2V steel at -70 ℃, it has good low-temperature impact toughness.
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
Strength
We have 18 technical personnel, a complete quality assurance system and experimental testing capabilities, chemical analysis, welding, mechanical performance laboratories and testing equipment, and close connections and cooperation with multiple universities, research institutes, and research institutes
