I'm also a fabricator and on joints like that, what I do is flip the whole thing over on my fixture table, and put a spacer under the joint and pre-bend the joint the opposite direction, so the weld pulls it straight, the amount of pre-bend takes a little while to get a feel for it, but you can get something that's basically dead straight without the heat shrinking steps (and more importantly for the jobs i've used it on, it leaves no marks on the surface) but joints where you can't do that, this is a great option

Yeah it was called back-breaking when I learned it. I don't think the take away of "just let it warp and flame straighten at the end" is a good paradigm to work from. Even when it goes well, and sometimes it really doesn't, you're going to wind up wasting time, gases, energy, and end up with embrittled zones or places where your finish is going to be compromised. Mitigate everything you can, use thermal processes to fix the rest.

@MrPaulviles24 күн бұрын
It pulled more because of the weight as well. Eg. If you weld something with a strongback on it the welding pull is minimal but if a piece of metal is unsupported and you weld the side in compression it will shrink more then the side in tension. That is why you needed more welds on your benchtop because the ends were not supported and the side you wanted to shrink was in tension. This is why pipe welders typically only weld 1/4 of the pipe’s diameter at a time so they can check for welding pull. Why they normally do the side in tension first. It pulls because the grain structures of the steel are changed, rapid cooling causes weaker grain structure then even extended cooling. Eg why cast iron has the entire piece preheated then the entire piece is cooled evenly over a extended period of time to prevent stress.
@ohane125 күн бұрын
Cool work. As an engineer (welder too), I spec weldments stress relieved to avoid the results you're seeing. In your case, it'd need to be held flat & in a big oven. What you made is weaker than perfect, but fine for it's purpose.

Hey great tip, I believe the cooling does not make it bend more but just makes it happen faster. We actually tested that using wet cool rags and the same piece was bent the same and allowed to cool naturally and the same result. Nice work.

Glad you discovered this. I did it with an Oxy/Acetate torch in the late 1950's (I was a farm boy in high school) because that's all Dad had. Worked a treat it did. Using compressed air to cool the metal which has been heated red hot may not be a good idea because while it's a mild form of quenching t could affect the metallurgical properties. On your project that wouldn't matter, but where the properties count letting it air cool is may be a better idea. the reason it works: The hot metal expands but the expansion is constrained by the rest of the tube so some of the hot metal is displaced.. When it cools displaced metal leaves less metal where it all was before. That shrinkage is what causes the bend to straighten.
@charlesvernon9590Ай бұрын
Tay, a shame it took you so long to learn something so basic. I've never used the TIG torch to heat the metal. Apparently it works well on thin material, I'll try it, thanks. I have a suggestion: If you continue to use compressed air for cooling, put an air connection on the air output of your plasma table. That air should be much colder than ambient temperature compressed air. OR: Use the old school method Clamp a straight edge to your work and after heating, repeatedly touch the heated metal with a cool, damp sponge until the desired level of shrinkage occurs. This method offers more control and works more quickly. Love your channel, keep up the good work.

Works on heavy solid stock too. Used to work for a father/son situation and the son assembled a big table for a church pulpit thing. I was occupied making all of the wrought iron details to go in there. Every face was as square as you could measure diagonally, but the whole structure was twisted as hell. Because it was heavy stuff we put tension on it strategically with straps. After I got them to stop fighting about it long enough that is... We used heat from the MIG to burn a line just like you did. A few spots required a tiny notch to be filled with a hot bead. It straightened right out without incident. And just like your setup it was way bigger than the biggest fixture in the shop, so there was no forcing it straight from the beginning. Think. Work smarter not harder.

@thebicyclesafarisАй бұрын
If you let the heated area air cool, it will still shrink the same amount, it will just take a little longer, but you'll maintain more of the metal's original properties. When you speed up the cooling process, it makes the metal harder, and more brittle. Not necessarily an issue with a table frame, but a serous consideration for any kind of structural work when employing flame straightening techniques. I use a rose bud for bigger stuff, or even just a cutting torch head does the trick if you're not depressing the oxygen lever.

I had that exact issue when fillet welding a 1/4" thick (stainless) flange to the end of some tubing for a hand rail. Shrinkage caused the flange to curl up like a bowl. I flipped it over and ran an autogenous bead on the back side of that flange right over the HAZ (heat-affected zone) and it fixed my problem very nicely. In your case, I think you will find that the edge welds induce some of that distortion in addition to the transverse ones you addressed. I built an automatic driveway gate from square tubing and put a row of mounting tabs along one corner of the top and bottom tubes to affix wood facing. This warped the entire gate like a banana. It was not enough to affect its function, but sighting down the edge reveals well over half an inch of bending over the 10' width of the gate. Stainless is really horrible in this; MUCH worse than normal carbon steel due to the low thermal conductivity and high coefficient of thermal expansion in stainless. I have a love/hate relationship with it. Mostly hate. LOL

I'm a boiler maker and when welding certain nozzles and pipes we have to keep them within .5 degrees of tolerance. When you weld a circular object it will tend to pull wherever you start/stop. So if you need to pull something to the right, start on the right side, weld around and end at the same point you started and it will pull that direction. Works best with Inconel and Stainless but carbon steel will behave but it shrinks less. Never thought of this trick though! Metal is a cool thing.

The best way to heat straighten is to constrain the material when heating so it can’t bend. Then remove the clamps quickly as soon as you finish heating and it will shrink . If you don’t, the metal will stretch away from the heat, then shrink back to where it was, pretty much.

Tay, if you really want to blow your mind try this. DIY Collector/Reducer. Take some exhaust tube and mark a starting point. Start your runs from the line moving the length of the tube and work in this order. Top run, rotate 180 degrees to the bottom. Run, rotate 90 deg. Rotate 180 run. So you are working in 1/4's. EG; top, bottom, left, right. Next you half the remaining gap between your welds and repeat the top bottom left right. Keep doing the step and you will see the tube end reduce in size as it cools. If you want a compound radius, start running your welds along the circumference remembering the more you overlap the runs the tighter the radius becomes. I have a 316 ss hourglass in my shed that I made sanded and mirror polished. It's about 12 inches tall with 1/4 plate for the ends and 3/8 bar connecting them and looks sick AF. Took me about 6 months to make as it was my "test piece" for setup.....lol

I'm not a metallurgist, but I think this works because during the manufacturing process (rolling, etc.) the individual grains of metals get stretched slightly beyond their preferred static shape. Then when heat is applied the grains expand of course, but then in cooling back down they return to their preferred shape. I think of it as taking a round balloon with some air in it, stretching it out, then heating the air within which makes the balloon expand, then as it cools it wants to return back to it's round shape. JMNSHO... your mileage may vary.
@notanymore9471Ай бұрын
Stainless is a bitch because it expands a lot and doesn’t conduct heat. Flame straightening is an old technique to fix distortion which is what you are demonstrating. Typically if you quench it with a wet rag you get more pull. Also using mechanical force helps quite a bit. Pre stressing it while you weld also reduces the overall warpage and if you get it right will prevent any distortion however it takes a good guess to get it right.
