Product Description

Product Description

SJ-101
Product Description:
Fluorine-type high alkalinity sintered flux, the alkalinity is about 1.6, the flux is a round particle size of 10 ~ 40 mesh, the bulk ratio: 1.2-1.25g/cm3. It has excellent welding process performance, stable arc combustion, excellent slag removal performance in groove, beautiful welding forming, and high low temperature impact toughness of deposited metal. Suitable for DC welding, welding wire to the positive electrode.
Meet the standard:
AWS A5.17 F7A4-EH14
AWS A5.17F7A2-EM12K
Scope of application:
With the appropriate welding wire, it can weld a variety of low alloy structural steel, such as hull, bridge, boiler pressure vessel, pipeline and so on. It can be used for multi-layer welding, double-sided single-pass welding, multi-wire welding and narrow gap submerged arc welding.
Welding position:
Horizontal and horizontal welding
Note:
Prior to soldering, the flux must be baked at approximately 300-350 ° C (572-662 ° F) for 2 hours.
Before welding, it is necessary to remove rust, scale, primer and other impurities on the surface of the base metal to obtain excellent welding deposited metal.
In the case of multi-layer welding, the bottom welding of groove welding requires a small current and welding speed.
New flux is added regularly to prevent flux defects and poor bead surface forming caused by flux reuse.
