Description:
SJ103 is a type of fluoride-Alkalinity and low-hydrogen sintered flux, with its alkalinity approximately 2.5.
Its grain is like light grey ball, size 10-40 meshes ( 1.7mm-0.38mm ). Direct current should be used while
the welding wire is contacted to the positive electrode. The ampere of SJ103's current carrying capacity
can reach 1400A. SJ103 is one of the few Chinese-produced big current cattying capacity welding flux. It
can be used for single-way or muti-way welding of 490Mpa grade steel, from which deposited metal
gained is of properties of high impact tenacity and crack resistance with extreme low harmful elements.
SJ103 can also be used for muti-way welding and narrow-gap welding of 590Mpa grade steels.
Usage:
Matching with corresponding welding wires of different grades, SJ103 can be in these areas: normal steel
structures Q345 and Q390; steels of boilers and pressure vessels, 19Mng, 16MR and 15MnVR; steels of
bridges-building Q345q and Q370q; pipeline steels X65, X70 and X80, etc; ship hulls steels A32, A40 and
D40, etc.

Cautions:
1.The welding flux must be baked for 2 hours at the temperature of 300ºC before build-up welding.
2.A sieve of 10-40 meshes is needed to screen out broken slags and delicate powder, when in recycle-
use, to use ensure the welding quality.
3.some foreign substances such as rust, greases and moiture on the weldment should be removed
before welding.
