Product Description

Welding flux 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.
