Introduction

 

WD-SJ301 is an agglomerated calcium-silicate type  flux with a basicity index of BIIW 1.0. The flux is spherical granular, grain size is from 10 to 60 mesh. It has excellent welding technology properties. Regularly shaped welds are deposited without reduction of area or interface notches. Slag detachability is good. A short slag is produced, thus allowing circumferential welding on small-diameter cylinders without the risk of uncontrolled slag. WD-SJ301 can be welded with AC or DC at up to 1200A (single-wire process). The production of large pipes (especially spiral pipe welding) is a typical application for this flux. Relatively high manganese pick-up is obtained, thus allowing the flux be used with wires with a low Mn content. The special production method ensures that the flux has low moisture pick-up and granular stability. Flux shall be capable of meeting the applied requirements. As the bulk density is low, so is the consumption rate.

 

Applications

 

Flat butt and fillet welding for steel frames, bridges, spiral pipes, pressure vessels and ships.

 

Characteristics

 

It has excellent welding technology properties. Regularly shaped welds are deposited without reduction of area or interface notches. Welding defects such as pits and blowholes scarcely

occur when steel plate is thin. Bead is smooth with beautiful appearance. It is suitable for welding of less than 20mm steel plate.
