Technical requirements: The sulfur content of the flux should not exceed 0.050%, and the phosphorus content should not exceed 0.060%. The flux is granular and should be able to pass freely through the flux supply pipe, valve and nozzle of the standard welding equipment. The particle size can be represented by different codes.

Submerged Arc Welding (SAW) is a highly efficient, automated arc welding process primarily used for joining thick sections of steel, especially in flat or horizontal positions. Its name comes from the fact that the welding arc is completely "submerged" or buried under a blanket of granular fusible flux material.
roles of the flux (shielding, slag formation, deoxidation, alloying, arc stability) are very important.
We supply high quality SAW flux for you.

Sintered flux is also called brazing flux, which has a very broad definition, including molten salt, organic matter, active gas, metal v***r, etc., that is, except for the base material and brazing filler metal, it generally refers to all substances used to reduce the interfacial tension between the base material and the brazing filler metal.

Application:

With appropriate welding wire (H08A, H08MnA), it can be used to weld boilers, pipeline steel and ordinary structural steel, etc.

Product precautions:

1. Oil, moisture, rust and other impurities should be removed from the welding area.

2. The flux should be baked at 300-350℃ for 2 hours before use.

The product is an important material to ensure the quality of the weld during submerged arc welding and electroslag welding. During welding, the flux can melt into slag (some also have gas), preventing the invasion of harmful gases oxygen and nitrogen in the air, and transitioning beneficial alloy elements to the molten pool, which plays a protective and metallurgical role on the molten pool metal.

Welding Flux SJ101

SJ101 TECHNICAL DATA
(1)Standard:
AWS A5.17/5.23 F6A0-EL8 F6A2-EM12 F7A2-EM12K F7A4-EH14
EN760 SA FB 1 65 AC H5
(2)Description:
SJ101 is an agglomerated fluoride-basic type flux. It is gray and round grain, mesh 10-60. it can be operated with AC and DC. ,the welding electric current can up to 1200A.It has excellent weldability, the welding bead appearance is beautiful and the slag is easy to remove. The diffusible hydrogen content in deposited metal is less than 5ml/100g,so it has very good toughness at low temperature, therefore, crack resistance is extremely high. It is suitable for submerged arc twin-wire, tandem and multi-wire welding as well as for welding with the two-run technique.
(3)Applications:
It can be applied to different welding wires(such as H08MnA,H10mN2,H10MnSi,H08Mn2MoA,H08Mn2SiA etc.) It is fit for welding of low-carbon steel and low alloy steel. Such as oil storage tanks, pipeline steel, ships, bridges, pressure vessels, penstocks, boilers and H-beam structural steels.
