TH·SJ501 AWS A5.17 F7AZ-EL12
SAW Agglomerated Flux GB/T 5293 S49A 0 AR-SU11
Applications:
It can be used in single-pass and multi-pass submerged arc welding for a carbon steel and low-alloy structural steels with appropriate wires (such as EL8, EL12, EM12 etc.).
Characteristic:
TH·SJ501 is a Aluminium-Titanium type flux, the grain size is 2.0mm-0.3mm (10-60 mesh), the basicity is about 0.8. Can be used welding steel that have little rusty or dirty surface, especially for the welding pipeline steel sheet with high speed.
Attention:
1. Before using, the flux shall be re-dry for 2 hours at 300℃-350℃.
2. Remove rust, oil, water and other impurities in the weld zone is suggested before welding.
3. The mechanical properties of all weld metal be decided by heat input, normally the small heat input will better than larger one.
