Have you ever welded something so thin and worn out that all you do is blow holes in it? Did you want to learn how to work around that and deliver a solid repair? We have the technique! In this episode, Justin the Fabricator shows you a few techniques on bridging gaps and filling holes on an old worn out Harley exhaust pipe.

Hear, hear! This is basically all the welding I have done, except usually rusty steel with a flux core MIG! All I care is did the damned stuff stick together and can I grind it down enough to be presentable if necessary? I've stuck a lot of dead exhaust systems back together that held for years.

@KathrynLiz1 4 жыл бұрын

Yes... the experts make it look so easy..... I'm still learning to control my puddle size properly and get the filler in there at the right time. I have a job at the moment that is quite critical and involves laying on some edge beads on metal less than 1mm thick (about 30 thou actually)..... So far so good, I haven't burned anything but I'm using less than 20 amps..... For really small stuff I have used .8mm Mig wire for filler.... works a treat. Hopefully I can develop the skill before I fall off my twig (nearly 78 now!)...... Great video. As other have said it's nice to know that the experts bodge it up on repair jobs.....

@nauroticdax 4 жыл бұрын

something I didnt quite realize until someone pointed it out really, when I finally got a decent mig I was really pushing to stack dimes and have amazing welds every time just like dad did (he is however a sheet metal fabrication engineer and has been for 30 odd years...the last time i saw him with a torch in his hand i was 10 so....yeah...) i was making jigs and frames and all sorts of stuff that i had big plans for and scrutinized every single weld. It wasnt until my lovely wife pointed out to me that I am NEVER going to see any of these welds again unless i look for them so surely its far more important to get a weld that is solid rather than pretty to look at. From the mouths of babes right? remember penetration over perfection at first and if it's something you're doing for yourself (or favor for a friend i guess) you can always just grind it down anyway

This has been so helpful in letting me know what I am doing has been in a way correct. I work in a factory that has given me a crash course in TIG and I have to patch mig welds that leak in pressure testing. A lot of my burnthrough patches look terrible but will hold. Using that bridge technique I think I can make them look much better. Thank you.

Sometimes you can use your chinese cold welder and a bit of 308 rod to tack this kind of stuff. Also you can use bass guitar strings that contain high quality steel core and nickel wounding. It forms quite strong weldings.

Good job Justin, talk about making a "silk purse out of a sow's ear ". You succeeded ! It is right up there with doing a plumbing repair on an old house. No matter how careful you are, once you touch a section, the next is likely to break or leak. At least that pipe will see more service. The scoot probably has other issues. Even Harley dealerships usually refrain from working on older bikes because of the probability of CRAP happening. RIDE ON ! J K

I did the same thing welded up a 1970's motorcycle exaust left it on the bike to insure it would fit. Pipe broke off at the reduction like yours. I did not use tig, I used 6011 on a busbox at 45 amps like you, you weld on the previous weld untill the gap fills in. That was about 2 years ago and is still working. As for the heat cycles it kills everything over time. Cheers

I was trained as an oxy-acetelene gas welder which is great for those sort of jobs but I now tend to use MIG on a low setting with 0.6 wire. As TIG is so similar to gas welding, I must get around to doing it. My welder has both MIG and arc terminals so i really ought to get to grips with it. Great little vid!

The other magical thing, is if the customer is willing to pay (or if it's your own project) welds like that can be ground or sanded down to look like they were never there- thats the beauty of TIG, it really blends the filler into the base material (especially on aluminum and mild steel). Awesome work showing how quickly this job can get done!

Nice work … Love the collection of Welding Machines. Have used most , Fronius, CIG, Lincoln, Liquid Arc etc. My Favourite was a Thermal Arc Inverter … It was a small unit similar to the ones behind you. It could do everything including Tig, Stick & Mig. 200 amp with minimal duty cycle restrictions. Smooth as silk to work with. Fronius Mig only were the standard in our workshop. 25 x 400 amp 40% Duty cycle. Great machines. Just the TA was tiny but could do the same work plus more.

I was thinking Co2 just cuz thats wat i do with gas tanks i weld. Usually usually because theres spots like that paper thin and rusted out. I dont purge them tho i keep it running in the tank when i weld it hoping it displaces the gas fumes. Idk that it helps the weld any, but i havnt blown one up “yet”. Lol. But i use that stuff to shrink bearing races too. But try not to cuz i need it for the kegerater. Hahahahaha

i did a repair on some dirty leaf thin stainless with 1.6mm sticks on a stick welder. it was crazy difficult, mainly cause i really couldn't see what i was doing due to where the hole was situated behind an electric motor. i was about 1 cm thinner than the hole i crawled in to to reach the rupture and i had to burn the sticks to about 10cm to be able to reach the part i was welding. i personally love these jobs, the challenge keeps me on my toes and because the equipment is important do i have about as much time as i want to ensure a good repair.

Welding rusty paper is a pain. I don't have a tig machine and my first mig is from Harbor Freight. But I still was able to weld up cracks in the exhaust header on my s-10 twice. I also had to make a patch for a quarter six hole. Thanks for the tips and commentary advice. It will help even on heavier stuff because almost all ranch repairs are on extremely rusty and rotted through metal. And most of my welding is done with a 20 year old Miller stick machine and 6011 rod.

If it's breaking in the same spot, put a sleeve inside to re-enforce it. Welding very thin metal cooks the material to a point that it heat treats it and make it harder but brittle.

10/10 backing sleeve. It’s just going to break again. You can tell by how it is. Use a small sanding drum to remove bumps/ buildup inside the pipe, cut a piece of new exhaust pipe, maybe 1” or 1.5” slip it inside, weld away!
