Wire speed?

admin

I have a stud that broke off in the head on my motorcycle.  A guy suggested that I get a washer that is just a bit smaller(inside hole of washer) than the stud and weld it onto the stud.  Then weld nut onto washer and back stud out.  This is a brand new stud that I broke when trying to screw it in.  So no problems with it being locked in.  Today I got a welder from a friend.  It is a 110v Clarke welder that I believe has .030 wire in it.  It has a min. and max heat setting switch and wire speed dial from 0-10.  I practiced alot today.  Got what looked like a good weld, but everytime I tried twisting the washer off it would come off pretty easily.  What I did was weld a bolt to a piece of metal and tried welding the washer on top of the bolt to duplicate what I would be doing on the bike.  The stud is a size 6m.  I am not getting penatration into the bolt. It looks good on the washer.  Just wondering if a slower wire speed gets me more penatration?  What else may I be doing wrong?Thanks
Reply:If the part is easily removable why not remove it and use a drill press and an E-Z out to unscrew it from the part.  I am not a fan of heat on exotic motorcycle alloys and if you drill and remove it you risk less damage.  You may even be able to drill it if you have access without even removing it from the bike.  I would use heat as a last resort.  If you just replaced it it should come out pretty easy once you get the E-Z out in it. Just a thought.I'm spending my Kids inheritance, I dont like him that much anyway!!!!!!Enuff tools to do the job, enough sense to use em.Anybody got a spare set of kidneys?  Trade?
Reply:Your machine does not have enough power to get penetration into the bolt, and a slower wire speed probably wouldnt help either.  Only thing you can really do to improve the situation at hand is to use a torch to heat the stud up and then try to weld the washer to it.Have we all gone mad?
Reply:Tried the easy out  with no luck, it broke.
Reply:sn0border88 thanks for the suggestion.  I will try this tom. on my practice piece.  Am I right though, a slower wire speed will give me more penetration?
Reply:No, slower wire speed will not give more penetration, just less amps and less fill.  Increasing the voltage (heat) will give greater penetration.  It's a small machine, crank it up!MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:I do this a lot. I just did motor mount bolts in a semi Saturday and a water pump bolt on a semi yesterday.   My experience is that MIG doesn't give a ductile enough weld for anything but the easiest bolts to remove. Yes it's easier to do but only if the bolt is almost ready to screw out already. The best method that I've come up with over the years is to use a stainless stick rod and butter the bolt with that. Then you can weld it with just about anything after that. I usually use 3/32 6011 for the welding of a nut on due to the fact that the stainless flux makes it hard to get a bond on the side of a hole. This can be a advantage when building a bolt up that's broken of down in the hole but it makes putting a nut on there hard.Millermatic 252XMT 304'sDynasty 280DXHypertherm PowerMax 1250Miller Trailblazer 302 EFIOptima PulserXR feeder and XR Edge gun and more athttp://members.dslextreme.com/users/waynecook/index.htm
Reply:Well I am about to give up.  I tried practicing tonight by heating up the bolt first.  Still unable to get enough penetration.  Guess I am going to have take it to a shop that has an EDM.  Irish I assume when you talk about the SS stick you are talking about using a stick welder?  All I have is the mig welder, and it is my buddies.
Reply:can you post a picture of the stud in the place where its in? can you get a nut on the stud even a thread or 2? i would and have put the nut on as far as you can, weld it on the inside. also is it a mig or fluxcore welder?what ever the case, crank up the heat all the way, if its a mig with gas, turn the w\s to about 70%, or 7 if it 1 to 10 dial. if its fluxcore wire, turn down the w\s to 1.5 to 2. point the wire right where the threads mate the beat you can. if you have to just tack it all the way around until it welded. then let it cool. when you heat up the stud it will expand, so let it cool completely, spray it with some penitrating oil and let sit a few more minutes, then twist it out. dont crank on it if its not moving. maybe even hit it with a hammer, not too hard, just a few taps. you could also take a cutting blade for a grinder, .045 thickness, and put a cross on the top of the stud and use a phillips screw driver. if you have one with a square shank, put an adjustable wrench on it while pushing down with your other hand to keep it in there. hope this helps.
