SJ101 is a kind of fluoride-alkaline-type slag-serial sintered flux,mesh 10-60. it has great capacity of sulphur 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.
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 current.
3.The weldng flux must be baked under 300-350℃ for 2 hours.
