99% of TIG Welding Beginners Don't Know This Trick

This was a trick that I WISH I knew as a beginner when I started to Tig Weld my own projects. But when you don't know, you don't know! So join me on this episode, and then you'll know!

Many years ago Porsche took the vent hole idea a step further. They put all of the vent holes inline to another tube when they created their "bird cage frame" On the 917. Then they would purge the whole frame as it was welded with Argon. After that they would purge and pressurize the frame with nitrogen and seal the frame off. Then they put a presssure gauge on the frame and if the pressure had dropped, they then knew the frame had cracked somewhere.

Fantastic., , this makes sense. It also explains that hole I always wondered about on my BMX frames. Great vid as always. 🔥

I’ve encountered this on not just aluminum but also stainless and mild steel. Thanks for confirming what I had suspected was going on!

The way I prevent this is to wait 15 seconds before closing. As the whole container is cooling its gas is shrinking. Then I quickly nail it shut. My heating is less than the containers cooling.

Your videos have been super helpful but I haven't been able to find a video on welding aluminum tubing. Specifically at work I weld aluminum plumbing for tanker trucks and it is pipe with angle fittings. The biggest issue is I have long pipes in a vise. So not only do I have to walk a circle around a pipe there is rarely a spot to rest my hand so I'm always hovering. I'd really appreciate a video trying to help me and it maybe some new content for you.

Better and easier to drill the vent hole in the end cap. It’s easier to place, easier to close up, and easier to finish off for aesthetics later.

Called Welding a Vessel. I have TIG welded 4130 Chrome Moly Aircraft motor mounts and under the manufacture's repair procedures, Drill a hole, do the welding, have it tested, fill the mount full of boiled Linseed oil, move the mount all around to "coat" the inside, then drain all the oil out through the drill hole, and finally install a spiral drive rivet in the hole. I have never had bad TIG results from any excising oil left inside previously.

Mig weld production we call these volcanoes, they spew out and spark just like a mini volcano. 😂

[flyinpolack]

spot on.
I have a 2" square cube that I welded full of water 25 years ago. Still full.
Snow was the key

always like your videos full of tips thankyou

[patricksalmon]

Incroyable astuce et pourtant si logique.
Merci Dusty pour ce partage.

I saw a hole in my frame, it made me weep.
😆

Learned this in the 80's when I started tig welding...when you weld aluminum tube always fins a spot that won't be seen and drill a small hole...if not you'll get blowback at the end of your weld.

Nice trick, one thing though, dont push so hard on your drill. the fact that you have markings on your project from the drillbit holder is just ugly if you are not going to hide it.

[michaelbigelow]

Another great tip Dusty. Thank you! My question is can I use the LaYZr green tungsten T3327GTM for mild steel aswell as aluminum?

[aguilao]

I give this tip to others at work, but it's hard to give a tip to someone who doesn't want to understand

[Kakydanou]

Leave the spot where you build your button free... let it cool down and then close it! No weep hole needed!

I would manufacture mobile platforms everywhere there was Joint I would drill a hole once it has been welded you don’t see the holes.
Aluminium welding of tubes and hollow section require that you drill lots of holes leading into an open tube that is sealed with a cap, or is going to be used for other things like an attachment of a latch.
Never mind if it happens drilling the hole where the expanding air has escaped from use cool air to keep the tube cool and you can easily repair it.
Depending on the type of conditions the job will be used in example the food processing industry we cannot have holes where insects and bacteria can buildup inside the tubes.
Sometimes even baseplates require a drill hole under the baseplate, unfortunately sometimes it doesn’t work.
Drilling a hole just next to the weld joint to allow escaping air to flow back into another area.
Often the baseplate will have a small hole for escaping air and these holes are sealed with a weld after cooling.
For industrial applications where the platforms are to be used in high heat areas such as near a Furnace we would drill holes in every tube to avoid weld failure while in service.
Hot gases will expand and contract your Aluminium tub and you will find that your welds fail after six months in service.
Hopefully this information will help people to trouble shoot I was self taught and I have my own business where I subcontract my welding services and skills in a number of industries
I’ve always been a tradesman who likes to share my knowledge and experience and feel a sense of pride knowing that I have helped a young fella or lady to become a great tradesperson.
