Hard-facing Flux cored wire weld fabrication accessories

GEH-547Mo is a hand electrode corresponding to GB/T984 EDCr-A2-15 of the Chinese national standard, which is applied to all kinds of surfacing and metal surface welding. It is mainly used for surfacing of valve sealing surface whose working temperature is lower than 510℃. The welding operation mode of DC reverse connection can be adopted. The metal for surfacing is 12Cr13(1Cr13) semi-ferritic chromium steel. Through the quality control of the supply of raw materials, advanced production technology and strict, high standard product quality inspection, this welding electrode suitable for 510℃ below the working environment is widely accepted in the market, the market feedback effect is good.

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.
