LH-SJ**1 is a kind offluoride-alkaline-typeslag-serial sintered flux,mesh ****0(2.**0.3mm).It has great capacity of sulphur removal,phosphorremoval and anti-rust.The technology has good performance,easy to deslag and with fine appeaeance of weld,even in the narrow gap of deep slope entrance.The metal welding seam has good plasto-toughness,with low diffution of hydrogen and fine cold and heat crack resistance.

Usage:
It can be applied to different welding wires and is fit for welding oflow-carbon steel and lowalloy steel.Moreover,it can be used for fast welding ofpipeline steel and forwelding ofthick wall structuresof different high-tensile steel.

Cautions:
1.The oil soil,moisture,iron and other foreign substances must be removed from the welding joint.
2.It is better to use directcurrent.
3.The welding flux must be baked under ******0Cfor 2 hours
