China wholesale Hard-Facing Manual Electrode Welding Makings Supplier - Hard-facing Flux cored wire weld fabrication accessories – Honest Metal

Application & Standard

Item number GEH-507Mo this hard surface wear-resistant hand electrode is mainly used in metal wear and by water vapor, weak acid, cavitation and other parts, such as valve sealing surface (working environment below 550℃), shaft, mixer pulp, screw conveyor blade surfacing. If used with D577 electrode, it can obtain good abrasion resistance. And the surfacing process is simple, no preheating before welding, no heat treatment after welding, using DC reverse connection.

Features

GEH-507Mo is a low sodium hydrogen type high chromium steel hardfacing strip, good operation, less splash, easy slag removal, beautiful shape, easy to carry out mechanical processing; The surfacing layer has the characteristics of air quenching, high medium-temperature hardness, good thermal stability and corrosion resistance. This type of hand electrode needs to pay attention to several matters before welding, so as not to cause unnecessary mistakes to the welding work. The first point: it must be dried at 300-350℃ for 1 hour before welding. Second point: the base material surface moisture, rust stains, oil to be fully removed. The third point: pay attention to the way of arc and arc, arc after the arc back burning, remelting arc point, arc to fill the arc pit.
