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. 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 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.
