Submerged Arc Welding
Butt and flat fillet welding of H-beam steel structure, spiral pipes,etc.C
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 40 mesh
Basicity: 1.0 ( BIIW)D
: Why more and more Customers choose our products:
1. Regularly shaped welds
are deposited without reduction of area or interface
2. Slag detachability
is good. A short slag
thus allowing circumferential welding on small- diameter workpieces without the risk of uncontrolled slag.
3. The production of large pipes( especially spiral pipe welding) i
s a typical application for this flux.
4. Relatively high manganese pick-up
is obtained, thus allowing the flux to be used with wires
with a low Mn content
5. As the bulk density is low, so is the consumption rate.Good efficiency!E
Damp flux should be re-dried at 300-350 ºC for 2 hours
.It could influence the welding bead!!
Rust, grease and Moisture on the weldment should be removed before welding.F:
