5.Characteristics
TY-SJ301 is an agglomerated calcium- silicate type welding flux.
Metallurgical behavior: High silicon pick-up is obtained. When the manganese content in wire is less than 1.5%, also a manganese pick up.
Grain size:10 to 60 mesh
Basicity:1.0(BIIW)
Regularly shaped welds are deposited without reduction og arear or interface notches. Slag detachability is good. A short slag is produced, thus allowing circumferential welding on small -diameter workpieces without the risk of uncontrolled slag.
The production of large pipes(especially spiral pipe welding) is typical application for this flux.
Relatively high manganese pick-up is obtained, thus allowing the flux to be used with wires with a low Mn content.
As the bulk density is low, So is the consumption rate.
Damp flux should be re-dried at 300-350°c for 2 hours. Rust, grease and moisture on the weldment should be removed before welding.
