I am working on a project where I need to weld a flange for a disc brake to one of these Spicer brand pinion yokes for an ORV. I have lots of experience welding with TIG and MIG, but no experience with Nickel rod, stick welding or welding to cast for that matter. I can't confirm this to be cast steel or cast iron. I have doubts that it is cast iron due to strength needed on a standard 3rd member/rear end, but I don't want to base my decisions with my hunch. Is there a welding process I can rely on with this unknown material, or would have to be cast steel for this strength needed? Attached ImagesLast edited by YFZ; 04-16-2007 at 09:17 PM.
Reply:I believe those are cast from Nodular Iron which can be readily welded with TIG or MIG using ER70S-6 with no problem.The ends that I buy for the 9" Differential housings I build are cast Nodular iron and I weld those with either process and regular ER70S.I'd try to contact SPICER (DANA products) before you weld it to verify it's construction but I know that the ends and yokes from Currie are all Nodular Iron.- PaulLast edited by ZTFab; 04-16-2007 at 09:37 PM.http://all-a-cart.comWelding Cart Kits and accessories
Reply:Those are Nodular..No worries.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:I forgot there were different types of cast iron and didnt know the ductile type was weldable. Thanks, Ill look into the TIG with ER70S-6
Reply:I Would Guess It Is Cast Steel,you Could Use Mild Rod 7018lh Or Wire, If Is Cast Iron I Would Use Nickle Cast Rod Only,works Better Than Wire
Reply:well, we used the ER70S-6 wire and did a weld test by breaking the weld in half. Then we were able to break some of it off of the casting with a chisel. I haven't used a nickel rod before, so I am clueless with it. Is that meant for filling cracks in castings or does that a wire have a strength like the ER70S-6?From what I understand the ER70S-6 has 70,000KSI of tensile strength. For the casting, I just need about 40,000KSI.One more dumb question...Is there only one type of nickel rod?
Reply:No, there are 2 types that I know of - Nickel 55 and Nickel 99. Nickel 55 - for cast iron, high strength, stronger than nickel 99, machinable. Nickel 99 - for cast iron, light to medium weight castings, higher ductile strength than nickel 55, easier to machine than nickel 55.John - fabricator extraordinaire, car nut!- bleeding Miller blue! http://www.weldfabzone.com
Reply:Do the spark test. Hit ist on a gringing wheel. Small almost nonexhistant reddish (sp?) sparks mean cast iron. Bigger yellow sparks mean cast steel. Cast steel welds great with 7018 OR ER70S-6.DavidReal world weldin. When I grow up I want to be a tig weldor.

Reply:________________________________________NICKEL 99 ENi-Cl / AWS A5.15-90 ELECTRODE FOR GREY CAST IRON REPAIR FULLY MACHINABLE AC/DC WELDING PROCEDURES: NICKEL 99 heavily coated electrodes are designed for welding cast iron in any position using direct current, reverse polarity, or alternating current. the electrode consists of a nickel core rod coated with a flux to produce dense machinable welds on cast iron. The edges of the casting to be welded must be free from skin and oil. The weld metal is deposited in short beads and may be peened lightly with a blunt tool to assist in relieving stresses and preventing spread of cracks. Preheating to 200ºF is useful in relieving stresses.

These electrodes are used to repair cracked or porous castings and to weld cast iron parts together or to steel. The weld metal is machinable and has approxi- mately the same color as cast iron.

Reply:The above is the info I found on the two nickel rods. One thing I didn’t mention is I will be welding these to C1018 steel. I notice the 55 mentions it can weld to nodular iron and the 99 says it can weld to steel... Would one electrode/TIG wire be suitable for welding mild steel to nodular iron?Last edited by YFZ; 05-01-2007 at 12:55 PM. |
