Any experience with Ferobide?

    i have some Ferobide tiles to weld and onto some soil engaging agricultural machine parts for a friend.
    Has any body ant experience welding Ferobide.
    The advice is not to exceed 130 amps due to heat input. I assume Pukse mig might be useful in this situation and help to keep heat input as low as possible

    Heat input isn’t just about amperage.

    Current x Voltage x 60
    ———————————- = Heat Input
    Travel Speed x 1000

    Being pedantic (:whistle:) this is actually a calc for arc energy.

    Actual heat input is arc energy x process correction factor. So what you have up there x 0.6 tig 0.8 MMA/mig or 1 SAW.

    Edit only winding you up mate.
    When I explain heat input from an effect POV I leave half the calc out anyway and use AxV/T. The rest of it is irrelevant unless you need to know the heat input figures.
    From a what changes what POV axvxt explains it all

    Sorry mate lost you a bit there. I think “heat input” is a bit of a misnomer as the below article from TWI explains.

    https://www.twi-global.com/technica...difference-between-heat-input-and-arc-energy/

    BS/EN Standards:
    Arc Energy = Volts x Amps x 60 divided by travel speed x 1000 = kJ/mm

    Heat Input = Arc Energy x K Factor (PCF) = kJ/mm

    AWS/ASME Standards:
    Heat Input = Volts x Amps x 60 divided by travel speed = J/in

    Yeah I understand that mate I’ve worked it to both standards lots of times. I had to as the drawings we used were often in either standard and as you know very different from each other from certain symbol layout meanings.
    I prefer to where possible to use the bs/en standard for Hi as using the pcf makes more sense imo. Aws can be calculated in j/inch or kJ/inch.

    You’ve both lost me with the calculations / formulas! Although I think I get the gist of what your saying! I.e. that a slower potential travel speed with pulse could increase heat input!

    Although the link to the Ferobide is pretty helpful

    Thanks james
