basic-covered electrode for depositing wear resisting overlays on structural members subjected to severe abrasive wear. Weld metal can be machined only by grinding. Suitable for hardfacing applications of crushing and grinding of coal, mineral, soil, rocks, excavator parts, bucket edges and bucket teeth, drilling bits, coal planes, conveyor screws. In case of very crack sensitive base metals, a tough buffer layer, made 307 electrodes, is required, before hardfacing. Preferred to use with DC, electrode in positive (+) pole and also possible to use with AC. |

Notes on usage:
Hold stick electrode as vertically as possible and with a short arc. Preheat heavy parts and higher-tensile steels to 250 – 300° C. Stick electrodes that have got damp should be redried for 2 h / 300° C.
We do hereby certify that; the weld metal deposit, has been tested, mechanically and chemically and all results are comply with the requirements of specifications of Elkadesia for engineering industries and the Specification of ASME II part C SFA 5.01 Class C5 and level of tests in J or 5.
