    Hi everyone
    What type of welding electrodes are always hand to have in storage?
    I have 2.5 and 3.2mm 7018(packages)
    2.5 and 3.2mm 6013(packages)
    3.2 6010 (package)
    I would like to have something exotic like stainless and special rods
    What you would recommend to pickup?

    If you got 309L and Inconel 625 you could weld just about anything.

    Either a 1.6 or 2mm 6013 rod is useful to have if you need to weld something you cant get to with your mig. If your welder can burn them 4mm is great on heavier stuff plus they are longer.;)

    I've a box of murex special metals rods that can weld any ferrous or s/s metal, different grades of steel, etc. Can't remember the name of the rods but they have got me out of a pinch a few times when something just won't weld with std rods.
    They are idiot proof & produce a perfect weld every time. Unfortunately they are quite expensive, probably £3 per rod now! :(

    1.6mm 6013 I have 20 of them I don't like this size ,are too springy , control almost nothing
    2mm 6013 definitely something to have I used a lot of them to stitch weld thinner section box tubing when I build a gate for my neighbor
    4mm 6013..... Isn't better go with 7018?
    About the special rods ,I think that they was somesort of stainless steel, maybe 309L or even 312L but 312L is not too expensive
    I found the other day on eBay 326L but I never heard about

    This is quite interesting Al. I take it you are referring to MMA electrodes but what about Tig? I always thought that Inconel wire was only good for fabricating Inconel components or is this wrong? Can you, for instance, weld stainless to mild steel using an Inconel wire?

    Inconel 625 will weld mild steel, stainless, nickel, cast iron, even Copper......it may not be the best choice but it will produce a sound weld. There is a stick available, and unlike some alloys the Stick, TIG, MIG are basically the same composition. Different manufacturers call it different names because Inconel is a trade mark of Special Metals. Just look for the AWS NiCrMo-3 specification in whatever form.

    6013 - 2.5 and 3.2
    7018 - 2.5 and 3.2
    316L - 3.2

    Should probably get some dissimilar metals rods, but TBH we don't have many cast iron failures... at least none that I'd like to repair.

    So 6013 and 7018 ok I have the general sizes needed
    316L I can get a free package but they are 2.5mm I believe it's not a major issue
    I love use those electrodes but I never used for the intended application
    Dissimilar steel rods ,can you give me the aws designation?
    I know that 309L and 312L could be good for the task but I can get easily 312L
    I read somewhere that 312L can be used to make a cushion pass before to use hardsurfacing rods
    Those last ones I've found eBay that are not to expensive and I can get them in small quantities .

    29/9 dissimilar metal rods are always handy to have

    Thank you for the clarification, I will get a couple pieces Inconel in for those "difficult" jobs.
    Having said that, they are all Bl**dy difficult at the minute!

    Just checked & those rods I have are Eutectrode 690sf.
    http://www.ceweld.nl/en/node/1929

    According to that site they are a 30/10 or a 312 rod. This box has lasted me years as I use them sparingly due to the cost but in certain situations nothing else will work so when they run out I'll certainly buy another box.
