Removing a broken bolt using a welder

August 13, 2019


often a ball to a store or shear off and you’ll end up we just slightly prowler the surface like that and a lot of times this will be on a machine is something where you can actually get to the back of it so I’ll just rig this up is a bit of a demonstration really there are several techniques for getting a broken bolt out lout but one of the easiest ones and certainly one of the quickest ones is to get a knot of the correct size put that on there and weld the knot on the inside and that likely sticks at a book and stored at a broken bolt and then it’ll help you get it out another important point is you’re far better off doing this with a MIG welder if you’ve got one I’m gonna be using an arc welder here which is a bit more difficult but it’ll still work all the same but it’s just a bit easier with a MIG welder saw this video assumes that you already know how to weld if you don’t know it so well that’ll be coming it alerted err so hopefully so we’re going to put the nuts on there now what we’re gonna do we’re gonna get the welders I actually switched on right now what we’re going to get it we’re just going to all the knots and then we’re just going to tack a bit of a weld on the inside as soon as we’ve got a bit of a weld on we’re going to start running devolved around the inside now an arc weld it’s not ideal for this because it creates a lot of slag which is going to be included in the weld bought for this it doesn’t really matter because all’s we’re concerned about is getting the damage ball to the damage thought outs of that all so what we’re gonna do is we’re just gonna wall that I’m gonna switch the welder on and we’re going to whack a bit of weld in there and till there’s enough well then source a little old and then we can just get our spanner and we can undo it when we remove the block and stored one thing you must do when you’re welding is of course where you correct PPE so I’m now going to put my visor on and you should also ensure that you’ve got adequate ventilation whenever you’re welding so it’s a little bit difficult for me welding here because of the position of the camera and the light but hopefully we’ll be able to get a decent shot of the actual weld going into the actual not so as well as welding something to the top of distort that’ll help as we move it the actually generated during welding is also going to help loosen the stored so it’s important that you get you not exactly over the stud where you want it so we’re now going to switch the welder on and we’ll just run a bit of a weld on the inside of the knot [Music] and you can say that that was actually glowing red out there was that much eating it so that will hopefully help us to remove the stud – I’ll take our spanner should now be able to move to stored and as you can see it has firmly welded and not to the store well as you can see that’s the actual weld on the inside of the knot so that’s one way to remove a broken stud

    How does the weld work,does it just melt the two together?

  • Reply benny bennys November 17, 2011 at 10:31 pm

    Thanks i must get one,look forward to your welding videos.

    just a warning for others, do not weld around galvanised metal! its toxic as the zinc fumes are generated!

    Thank you for another great video. I do hope you keep making videos and welding would be a great topic.

    Great idea. I was planning on using a welder to get a bolt out, but I couldn't think of what to weld onto it.

    I need help mate! I broke one of my 8mm screws in one of my oil filter holes. But it broke off a cm in the hole. What should I do?

  • Reply Joachim Osmundsen September 27, 2012 at 6:05 pm

    In my opinion bolt extractors might be a worse off option. They break so easily, which causes a bigger problem. Use a chiesel and try to hit the bolt in the direction you disassemble it. In theory when the head is off the bolt its not pulling on the threads, which means it should be easy to remove. Try this before you do something more drastic. If you spray in some wd40, and hit the bolt with a hammer and chiesel it might be removable.

    I welded a nut to my cars oil sump plug since (hex socket hole rounded off) it was made of steel and my sump was made of aluminium and they had corroded together (technical name for this escapes me!) I had to weld upside down while under the car, not fun but it worked. Holding the nut in place with a piece of wood just cut to the right length. mig welder was ideal since it allowed for small precise tacks

    Dissimilar metals can suffer from galvanic corrosion – essentially they set up a small battery with the moisture present and one of the metals gets dissolved and deposited on the other. In the olden days they used to use zinc nails to fasten the copper sheets onto warships – I think this is how they figured it out initially. The saltwater and dissimilar metals caused the hole to increase in size until the plates fell off.

    Galvanic corrosion! I knew there was a technical name for it!!
    Thanks

    Very nicely done.

  • Reply St Pauli May 3, 2013 at 4:57 pm

    using this method is difficult to do because a lot of times you hit the rod on the nut and don't get a good weld;I cover the rod with shrink tube to help as my vision and steadiness have gotten worse over the years.I like the superglue cheat!great advantage

    its cool that u can kinda c thought the nut while he's welding

    I need you to come to my house and help me with this old truck I have and a couple of bolts. I wonder if paying your airfare to and from and all your expenses is cost effective? LOL.

    Great video man! Thanks!

  • Reply Dan Kennett August 15, 2013 at 12:00 am

    No, No, No, Weld a flat washer to the broken stud and then weld the nut to the washer. If it is really stuck, also weld the nut hole.

    Ive be using this metod for many years but i start making some points and clean the slag, one in the top of each other until i have grown a stack of weald at least the heigh of my nut then i make a final weld, that help to prvent th nut of moving and the temperature helps removing the bolt

    theirs nothing bad about arc welders vs mig really. some may call it old fashioned, but its built many bridges, and similar things where sheiding gas is not practical or gets blown away. theirs a rather nice feeling once you take a 7018 rod to something its going to stay put with minimal hassle.

    Interesting technique. I bet this has saved your hide a few times. I will give this a try with my everlast welder.

    Could you not have just drilled it out?

  • Reply Lester Garcia July 17, 2019 at 10:57 pm

    @Ultimate Handyman can this technique also remove a wheel stud that has been overtorqued? my wheel nut has split off from its ball seat base when i used a breaker bar to remove it and now all thats left is the wheel stud & ball seat portion of wheel nut

  • Reply Chris McEvoy July 22, 2019 at 11:16 am

    Can I do this with a Flux welder or will I have issues?

  • Reply GUY Fitzsimmons August 1, 2019 at 9:58 pm

    Put a washer below the nut first to raise the nut up from the surface giving extra clearance from the surface and also protection from weld running out on to the work surface fusing the stud to piece your trying to remove it from defeating the whole object as the molten metal will always take the path of least resistance so if theres any gaps it will find them. Then put the nut on top of the washer then push the welding rod straight down vertically into the centre of the nut onto the broken stud so your penetrating into the top of the stud and then just fill the centre of the washer & nut with weld. Then let it cool right down before trying to undo it as when it cools it will retract /shrink making it even easier to remove. You can also drill down the centre of the broken stud as well to get even better penetration on really stubborn studs and repeat the process as above.
