Product Description
Welding flux:   TY. SJ301

Certification: ABS, CCS

Specification:

AWS A5.17 F6A0-EL8 F7A2-EM12K

EN760 SA CS 1 89 AC H5


Applications:

Butt and fillet welding of minature LPG tanks, Structural steels, Gas bottles,

Pipeline steel, especially Spiral pipes welding.


Characteristics:

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

notches.

5. Slag detachability is good. A short slag is produced, thus allowing

circumferential welding on small-diameter workpieces without the risk of

uncontrolled slag.

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.


Usage:

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.


Package:

25kg per kraft paper bag; 1000kg per Jumbo bag


Cautions:

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.
