Tig Welding Cast Aluminum With Helium Mix

[Altprophet]

Should drill the ends of the cracks otherwise the cracks will reform at the stress points and the welding can chase the cracks further into the material.

People allways told me its to hard to weld aluminium but when I started doing it, its actually easy and up today i have never gotten any problems and I have done it for years.

Love how you capped everything after filling it in that’s a cool trick

[EquitySolutionRayRaz]

Wow, someone actually showing a skill and not some bullshit method of garbage ! Nice ! I was always told to drill holes at the end of cracks in aluminum to prevent further cracking and cast iron etc but I believe if you just prep deep like you did it’s satisfactory!

My 1st TIG weld in my life was case aluminum motorcycle cases. I learned a lot and made it work. It was not nearly as pretty as that, but it held oil for the rest of the bikes life.

Heli arc is called this because helium was originally used in this welding process, it cools the base material and weld puddle more efficiently preventing overheating that can cause more stress cracks

[jefferp]

That looks like a good casting. Welded really good.

In the early days, this was called Heli-Arc welding. Origin of TIG. Came from aerospace. Now argon is often used. I am no pro welder but I love my vintage, analog gage miller welder with a tig torch cooler.

Did the helium bring out more pin holes or impurities than straight argon

Where did the giant hole at 0:11 come from💀

You need to find the end off the crack an drill a hole
So as the crack doesn’t want to carry on regardless
But good work

I've done hundreds of repairs like this but this video doesn't do it justice what a pain in the ass it can be. Sand cast aluminum has so much junk in the metal it can take doign this process 5 times before you get good results. I do enjoy the process though and make good money doing it. Saved lots of rare parts too.

A Crack grows faster the pointier the Crack tip is. Drilling the Crack tips into circular holes slows the Crack tip propagation down

[ChaseFrancis-ldeg]

I mean, it’s technically capped but repaired aluminum is just inherently shit

[johnbelwell]

It's just an oil pan, it will be alright, but i feel like the weld should have been hotter and the aluminum ground further.

Does this work with concrete foundations? Asking for a friend

[foxxnight]

how do you start with cracks and end up with a giant hole holy sht man it must cost an arm and a leg to get something repaired by this guy lmao

[waymenlawrence]

Helium vs Argon what's the difference?

. me an soldado un múltiple de escape y Soy testigo de la avilidad del qué me arreglo el trabajo fue espectacular y no se notaba nada
