    Product Description

    Classification :

    • IS : 814 - 2004 : EB 5426 H3 JX
    • AWS/A 5.1 : E 7018

    Description :

    A heavy coated low hydrogen, iron powder type electrode ideally suited for producing tough and ductile welds of radiographic quality in boilers, pressure vessels and heavy structures subjected to dynamic-loading. The smooth, soft arc, easy slag control, all positional welding, low spotter and excellent slag release provide maximum weldor-appeal. The electrode has a metal recovery of minimum 110%. GM 18 has very good impact values down to minus 30oC. Typical hydrogen content is 3 ml/100 gms of weld deposit.

    Applications:

    • Boilers : Earth moving machinery
    • Pressure Vessels : Storage tanks
    • Pipe lines : Penstocks

    Recommendation :

    Retry the electrodes at 350oC for one hour or at 250oC for two hours. Keep the re-dried electrodes in a holding oven having 70o to 100oC temperature. Use electrodes directly from holding oven. Use electrodes within recommended current range.

    Welding Positions : F,H, V-up, OH
