Specification: EN760 SA AR 1 88 AC H5
AWS A5.17/5.23 F7A0-EL12 F7A2-EM12K
Applications:
Butt and flat fillet welding of miniature LPG tanks, ships, vehicles, agricultural implements, machinery,
boilers, bridges, structural steels.
Characteristics:
TY-SJ501 is an agglomerated aluminate-rutile type flux.
Metallurgical behavior: High silicon and manganese pick-up is obtained.
Grain Size: 10-60 mesh
Basicity: 0.7 (B||W)
The welding performance is excellent.
Slag detachability is very good, especially at high speed.
Welding porosity scarcely occur.
Its welding speed can travel up to 120cm/min. It is particularly useful for welding tube-web-tube joints of
finned tubes.
TY-SJ501 is useful for welding thin plate in single pass and limited pass.
The flux has low moisture pick-up and granular stability. As the bulk density is low, so is the consumption
rate.
Damp flux should be re-dried at 300-350ºC for 2 hours. Rust, grease and moisture on the weldment
should be removed before welding.
