Product Description

GUJIN® is Welding flux SJ101 manufacturers and suppliers in China who can wholesale Welding flux SJ101. GJ.SJ 101 is a kind of fluoride-al kaline-type sla g-serial sintered flux, mesh 10-60(2-0.3mm).it has great capacity of sulphur removal,phosphor removal and anti-rust. The technology has good d performance, easy to desla g and with fine appearance of weld,even in the narrow gap of deep slope entrance. The metal weldin g seam has good plasto-toughness, with low diffusion of hydro gen and fine cold and heat crack resistance.

Usage:

It can be applied to different we'lding wires and is fit for welding of low-carbon steel and low alloy steel. Moreover, it can b e used for fast welding of pipeline steel and for welding of thick waffstructures of different high-tensile steel.

Cautions:

1.The oil soil,moisture,iron rust and other foreign substances must be removed from the welding joint.

2.It is better to use direct arrrent.

3. The welding flux must be baked under 300-350℃ for 2 hours.
