Product Description

Solder flux

TY.SJ301

Quality system: ISO9001:2008
Certifications:   ABS

Specification: AWS A5.17 F6A0-EL8 F7A2-EM12K


Applications: 
Butt and fillet welding of minature LPG tanks,Structural steels,Gas bottles,Pipeline steel,especially Spiral pipes welding.

Characteristics:

1. TY.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 ºC for 2 hours.Rust,grease and moisture on the weldment should be removed before welding.

Spiral pipes welding:
