Gas shielded flux cored wire with high strength steelSHJ807Description: SHJ807 is a metal cored low alloy high strength steel welding wire. When welding, the welding wire is connected to the positive pole and 80%Ar+20%CO2 mixed gas or 100%CO2 is used to protect the welding wire. The welding process has good performance and high welding efficiency. Deposited metal has good crack resistance and high toughness. The workpiece should be preheated in the range of 250~350 centigrade before welding and be treated by tempering at 620 DEG C after welding.Application: it is used for welding high strength steel of relative strength grade, and can also be used for surfacing of ordinary wear-resistant parts or for transition layer of hardfacing parts.Typical chemical composition of deposited metal (%)Ingredients C, Mn, Si, S, P, Cr, MoThe measurement value of 0.065 1.63 0.3 1.05 0.48 0.025 is less than or equal to 0.025Typical mechanical properties of deposited metal: (690 * 1H tempering)Tensile strength (o b) Mpa yield strength (by 0.2) Mpa (5)% elongation impact energy of Akv (-40 C) JMeasured value 8207601838Recommended parameter: (DC+) (1.2mm)Welding current (A), welding voltage (V), dry stretch length (mm), gas flow (l/min)200~260 28~32 15~25 20Matters needing attention：Remove rust, oil stain and moisture before welding.Remove welding slag between welding layers, and avoid slag inclusion.When welding, preheating and post heat treatment are carried out according to process requirements.Welding wire should be kept in a cool and dry place. It can be used up in time.
Simply stated, the tensile strength grade is a low hydrogen sodium structural steel electrode at a rate of 800 kg per square millimeter! Mainly used for welding of steel of the same strength grade! Generally used for low carbon quenched and tempered steel welding!
