Product Description

sj301G
comply with standards ( Standards)

• • GB/T 5293 S 49A 2 AB-SU26  AWS A5.17: F7A0-EM12K

illustrate:

• aluminum-alkali type sintering flux, alkalinity is 1.36, particle size is 10-40 mesh, loose packing ratio: 1.2-1.25 g/cm3. recommended ac or dc reverse connection. mainly used for ordinary structural steel, X42,X46 grade pipeline steel welding, this flux has excellent welding process performance, is suitable for high current welding, the weld shape is beautiful, and the weld metal has good mechanical properties under high heat input conditions.

use:

• with appropriate welding wire, it can be used for single-wire and multi-wire welding of ordinary pipelines and steel structures.

  • Precautions:

  • Before welding, the flux must be at about 300-350 ºC(572-662ºF)Bake at room temperature for 2 hours

    Before welding, be sure to remove rust, scale, primer and other impurities on the surface of the base material to obtain excellent welding deposited metal.

    In the case of multi-layer welding, the root welding of the groove welding requires a small current and welding speed.

    Add new flux regularly to prevent flux defects and poor weld bead surface formation caused by reusing flux

  • package style:

  • 25Kg/Bag, 25 Kg/Barrel, 400 Kg/Ton bag
