Introduction
WD-SJ101 is an agglomerated fluoride-basic type flux with a basicity index of BIIW 1.8. The flux is spherical granular, grain size is from 10 to 60 mesh. As weld metal is very purity, the diffusible hydrogen content in deposited metal is less than 5ml/100g, so has very good toughness at the low temperature, therefore, crack resistance is extremely high. WD-SJ101 assures excellent weldability, bead appearance is beautiful, slag is extremely easy to remove. WD-SJ101 is suitable for submerged-arc twin-wire, tandem and multi-wire welding as well as for welding with the two-run technique. 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 of mild and high tensile strength steels for frames, bridges, pipes, pressure vessels, rolling stock, offshore structures and ships.
Characteristics
It has excellent welding technology properties for fillet welding of thick plates. Regularly shaped welds are deposited without reduction of area or interface notches. Blowholes scarcely
occur. Satisfactory weldability and mechanical properties are obtained with heat input.
Main Constituents (%)
Typical mechanical property of deposited metal
Typical chemical composition of deposited metal (%)
Notice:
1. Flux should be redried at 300~350°C for 2 hours.
2. All dust, oil and rust should be removed.
