Welding flux: TY. SJ301
Certification: ABS, CCS
AWS A5.17 F6A0-EL8 F7A2-EM12K
EN760 SA CS 1 89 AC H5
Butt and fillet welding of minature LPG tanks, Structural steels, Gas bottles,
Pipeline steel, especially Spiral pipes welding.
1. SJ301 is an agglomerated calcium-silicate type welding flux
2. Metallurgical behavior: High silicon pick-up is obtained. When the
manganese content in wire is less than 1.5%, also a manganese pick-up.
3. Grain size: 10 to 60 mesh Basicity: 1.0(BIIW)
4. Regularly shaped welds are deposited without reducion of area or interface
5. Slag detachability is good. A short slag is produced, thus allowing
circumferential welding on small-diameter workpieces without the risk of
6. The production of large pipes(especially spiral pipe welding) is a typical
application fo this flux
7. Relatively high manganese pick-up is obtained, thus allowing the flux to be
used with wires with a low Mn content.
Necessary process before welding:
Damp flux should be re-dried at 300-350 º C for 2 hours. Rust, grease and
moisture on the weldment should be removed before welding.
The flux is fit for the submerged arc welding of low carbon steel and low alloy
steel, as well as the fast single-way and double-surface welding of thin steel
sheet. And it is usually used for the sumberged arc welding of liquefied gas
storage tanks, gas bottles, and pipeline steel.

1. The welding flux must be baked for 2hours at the temperature of 300-
350ºC before build up welding
2.Some foreign substances such as rust , grease and moisture on the
weldment should be removed before welding.
