Welding flux SJ101 is a kind of fluoride-alkaline-type slag-serial sintered flux, mesh 10-60(2.0-
0.3mm).It has great capacity of sculpture removal, phosphor removal and anti-rust. The technology has
good performance, easy to deslag and with fine appearance of weld, even in the narrow gap of deep
slope entrance. The metal welding seam has good plasto-toughness, with low diffusion of hydrogen and
fine cold and heat crack resistance.
Application:
This flux is alkaline flux, which belongs to the metallurgy neutral, It hardly increase Si and Mn on
weld bead. High impact toughness at low temperature. The flux has excellent welding performance,
excellent slag removal, and good bead appearance. With different welding wire welding a variety of low
alloy structure steel, for example pipe, boiler, pressure vessel, bridges, ship etc.
Horizontal welding of oil storage tanks, ships, bridges, pressure vessels,
penstocks, boilers and structural steels.
Characteristics:
SJ101 assures excellent weld ability, and the welding bead appearance is
beautiful and the slag is easy to remove.
The diffusible hydrogen content in deposited metal is less than 5ml/100g, so it
has very good toughness at low temperature, therefore, crack resistance is
extremely high.
It is suitable for submerged arc twin- wire, tandem and multi- wire welding as
well as for welding with the two- run technique.
Damp flux should be re-dried at 300-350ºC for 2 hours. Rust, grease and
moisture on the element should be removed before welding.
Attentions/Cautions:
1. Flux must be re-dried at 300-350 °C (572-662°F) for 2 hours before welding.
2. Remove all rust, scale, paint and etc., so as to obtain excellent weld material.
3. In the multilayer welding, groove welding of baking welding demand low welding current and speed.
4. Adding new flux regularly in order to avoid causing welding defect and bad welding bead appearance
when using flux again.
