Product Description

Product Description

SJ301T
Aluminum-alkali neutral sintered flux; Alkalinity 1.0; Granularity 10-40 mesh; Loose load ratio: 1.2-1.25g/cm3. Single-pass butt welding or fillet welding for carbon steel, can be used for both AC and DC. This flux provides outstanding welding process properties, including stable arc, excellent slag removal and weld formation. Especially suitable for ring seam welding, but also suitable for high-speed welding.

Meet the standard:
AWS A5.17F7A2-EM12K

Scope of application:
With appropriate welding wire, it can be applied to the welding of conventional pressure vessels, shipbuilding, steel structure Bridges and pipeline steel.

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.
