I fusion welded my dump pipe and wastegate pipe pie cuts 1mm tubing. No back purge and colorless on the top. Check it after every race holding up so far haha.
Cp2 ti from monkey fab. I used 304 16ga stainless for the pre turbine side. Im kind of debating redoing it in ti. Im a huge weight savings addict. Already well into the carbon and titanium rabbit hole.
Odd question but what do you do for haircuts and styling. We have pretty much the exact same hair. Also if you have any extra tips. We’re welding 1/2 tube .035”/.062” thick trying to get full pen and avoid the blueing on the bottom half of the tube. I know you said it gets harder on smaller tube but was wondering if you’ve learned any new tips since the video?? Thanks!
When the tube is that small its hard to get the heat to dissipate enough to prevent bluing or coloring. If I was you -- I would turn the post flow up to like 15 seconds and just let it cool with post flow for a while. Then wait a bit in between welds to let the tube cool down just a bit. However, welds are completely fine with color!
Great video mate, super tidy and very professional! You didn't mention keeping the filler in the gas coverage area and noticed a few times you quickly pulled the filler away, I've seen with stainless this can put oxidised filler back into your weld pool. Is this less of an issue with titanium? Cheers.
Thats a great point thank you for mentioning that! To be honest, I should prrobably get better about that myself, Its not really something I think about. I pull it a away quickly quite often and I dont really see a difference... but I can always improve! Cheers
@@KULLYCO Various ti alloys are sensitive to scratches. They can set up fracture planes that can cause the ti to suffer fatigue failures along the scratch. Like putting a scratch on glass to cut it. Sensitive to the stress riser presented by the scratch. This is why, back in the day, the FIA disallowed ti for suspension components.
I've never heard anyone else mention waiting at the start with pulse. Just ran outside and tried it, helped a lot.
Haha right on man! Glad I could help:) thanks for watching
very interesting and instructional video as ever, thank you a lot!!
Thank you man! I appreciate you watching - I’ll try and keep the content coming !
You’re a pro. Looks awesome! Thanks for the video.

Fantastic
Thank you! Appreciate you watching

Haha right on! well that is encouraging to know:) Next project you should try purging! Then you wont have to worry at all !
Bud did You use titanium or stainless?

How do you decide what diameter fill rod to use?
A good rule of thumb is use the same thickness filler as the material thickness your welding. But it’s not always accurate . In this case it is

Strong, light, notch sensitive
What you mean notch sensative !?
@@KULLYCO It's not really a concern for exhaust systems but more so for structural (i.e. suspension/chassis, etc.)
@@butziporsche8646 Right on! What do you mean, though- notch sensitive? Just curious. Also- I've built some titanium frames as well! Kinda neat

Thank you for sharing your knowledge.
Didnt know Timothée Chalamet was such a good welder
Haha yes turns out he is pretty handy with the torch!
“O-taw-genous” not auto genius
My apologies:) well noted ! Thanks
I was like….what? lol never heard anybody say it like he did
