Welding Flux For Submerged ARC Welding, Agglomerated Flux

Description:
lh-sj101 is a kind of fluoride-alkaline-type slag-serial sintered flux,mesh 10-60(2.0-0.3mm).it has great capacity of sulphur removal,phosphor removal 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 of low-carbon steel and lowalloy steel.moreover,it can be used for fast welding of pipeline steel and for welding of thick wall structures of 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 direct current.
3.the welding flux must be baked under 300-350âºc for 2 hours
