    Ni-cads... Nickle rods any time that you weld hard or two different kind of steel together.

    It will take the heat treat out of the gear.

    Er312 is your friend. Lincoln used to sell it as their "All Purpose Maintainance Filler". You can also find it now labeled as "SuperMissileWeld".

    I use it on gears and bearings. The high ferrite content and fast freeze attributes help prevent cracking. Tensile is above 100ksi which is a better match to the gears. You can find it as Tig filler or stick electrodes.
    Weld like a "WELDOR", not a wel-"DERR"

    Thank you I thought it would be different welding the too parts together I will read up on the nickel rods
    This is where I want to weld the housing slides over it so if it doesn't work or it breaks I can take it apart

    Re: Welding a atv rear axle to its ring gear

    A lot of axle material and even the gears have a teeny bit of vanadium. Increases toughness and corrosion resistance. Do a search with 'axles crankshafts vanadium' .. Don't know that an atv would warrant a more expensive alloy but still it is pretty much standard practice.

    Re: Welding a atv rear axle to its ring gear

    Id be worried about the axle wanting to break at the weld if that's a one piece axle like on a sport model.

    I think I would do a couple of good tacksmaybe 1/4 to 1/2' long 180* apart.

    The mentioned er312 or, since I have them on hand, I would use er308l, either will get the job done. Just don't cook the axle to much.

    Probably don't need much.

    Also, if I didn't have any super duper NASA missileweld, I'd probably use 7018, cross my fingers, and call it macaroni. I've gotten away with a lot of things I probably shouldn't have with 7018.

    Re: Welding a atv rear axle to its ring gear

    Would you do a couple of tacks or weld all the way around? Does it need to be heated first ?

    Re: Welding a atv rear axle to its ring gear

    I would do a couple of tacks, this will minimize heat input which will help with warping
    , the gear at least will have some heat treatment and the axle as well, if you don't know what you are doing then preheating may affect the heat treat. a couple of tacks with the 312, quick & easy, don't overthink it, make sure you get it cleaned of the gear oil, whatever you do, DON'T USE A CHLORINATED SOLVENT OF ANY KIND, you can use non chlorinated brake cleaner, spray carburetor/fuel injector/throttle body cleaner etc. I think the key is to minimize heat input, thus the 2 tacks, the first tack is going to try to pull the axle, and the second will pull it back, hopefully the gear is not sloppy loose on the shaft, if it is then maybe 4 tacks working to make sure the gear is straight and the backlash is right. Honestly I think 2-4 1/4" tacks will be just fine. Lotsa folks tend to overweld things like this.

    Try searching for 312L-16.

    https://store.cyberweld.com/hobart-3...80630-rdp.html

    https://www.ebay.com/itm/Stainless-S...-/323155709819

    Certanium 707SP is also 312L-16 as far as I know but very expencive.

    And the Super Missileweld Shovelon mentioned.

    In Europe Lincoln has the Limarosta 312 but I can't find that one on the Lincoln USA site.
    I have 312L-16 rods from Lastek, but those are probably not available in the USA.

    If You really can't get some 312 rods, 309 will do it.
