Welding Flux is a material that make the weld seam stronger and cleaner. It can protect the weld seam from the influence of substances such as oxygen and moisture in the air, which will weaken the weld seam.

Welding Flux also can maintain the stability of the welding process and remove dirt or impurities from the metal.

Product Description of SJ-101: Fluorine and alkali resistant neutral sintering flux, with an alkalinity of 1.4. It is a light gray, round particle with a particle size of 10 to 40 mesh, and the bulk density is 1.2 - 1.25 g/cm³. With It has excellent welding process performance and high welding speed. The arc burns stably, slag removal is easy, the weld shape is beautiful. Due to the use of special manufacturing techniques, the metallurgical reaction is fully carried out during welding, the deposited metal is pure, and it has high low-temperature impact toughness. With the appropriate welding wire, it can be used to weld various low-alloy structural steels, such as ship bodies, bridges, boiler pressure vessels, pipelines, etc. It can be used for multi-layer welding, double-sided single-pass welding, multi-wire welding and narrow gap submerged arc welding. Compliance with standards: GB/T 5293-2018 S 49A 4 FB-SU34

GB/T 5293-2018 S 49A 2 FB-SU26

SJ-301 Product Description: Silica-calcium type active sintered flux, with an alkalinity of approximately 0.8, particle size ranging from 10 to 40 mesh, bulk density: 1.2 - 1.25 g/cm³. Excellent welding process performance, stable arc burning, easy slag removal, and beautiful weld formation. The physical properties of the slag are short slag.

During short arc surface submerged arc welding, the slag does not flow. It is particularly suitable for welding ordinary steel structures, steel pipes, welding of grade A and B pipeline steel, and the slag has the characteristic of short slag, especially suitable for circumferential welding.

Complies with standards: GB/T 5293-2018 S 43A 2 CS-SU26

GB/T 5293-2018 S 43A 0 CS-SU08A

Product Description of SJ-101G: Special sintered welding agent for fluorine and alkali resistant spiral welded pipes, with an alkalinity of 1.6, it is a light gray circular particle, with a particle size of 10 to 40 mesh, loose bulk density: 1.2 - 1.25g/cm3. It has excellent welding process performance and high welding speed. The arc burning is stable, slag removal is easy, the weld seam is beautiful in shape. When combined with H08MnMoTiB, H08MnNiTiB etc. welding wires, it can be used for welding spiral welded pipes and straight seam welded pipe joints of oil and gas pipelines; when combined with H08C welding wire, it is especially suitable for welding X65, X70 grade spiral welded pipes, and the welding speed can reach above 70m/h. Conforms to standards: GB/T 5293-2018 S 49A 4 FB-SU34

GB/T 5293-2018 S 55A 4U FB-SU1M3TiB

1.The amount of flux consumed is small, and the production cost of welding is low.
2.The weld seam is uniform and is less likely to produce pores and slag inclusions.
3.Deoxidizers and alloy elements can be added to improve the mechanical properties of the weld seam.
4.The formulation of sintered flux is scientific and flexible, and the welding process has strong adaptability. It can be used for welding under various working conditions, with excellent slag removal performance and good weld formation.
