If we're still working on the box tomorrow, I'll try to weld a SKULLY on it.

This is TIG welded or O/A? Man, this is IMPRESSIVE! I am amazed!! My stick skills are inexistent compared to this.Everytime the instructor tells me anything, it starts with "Don't you do it like this." or "Don't tell anyone else."
I haven't turned in my projects. If we have free time, I can always try a do-over. Just need to turn them in before the last class.
Learned on the Outside Corner project not to stay to long on the peak, and to bring the puddle farther down on the sides for better penetration. Didn't understand that when I welded these coupons. Have better penetration now.
Not cleaned up.

Nice! 👍 Crazy about the dirty torch, but glad you sorted it outMade a box tonight. Cut the coupons and welded them together. Not even in the syllabus. Instructor wants everyone to move on at the same time. Says we're not going to weld with filler rod until Monday.
Burned a small hole in my box. Instructor told me to use a little filler rod. "Don't tell anyone."
He said we we're going to test them for water-tightness. Guess he forgot. Maybe tomorrow.

Instructor told us to finish the Box project tonight. Mine was done last night. I could do another one, but I'd rather do something new.
I go into his office and ask him if I can try to weld a skully into the side of my box. He stared at me for a good 3 seconds, and said- FUCK YEAH!!! I'm guessing no one ever asked him that.
It was fun because I didn't move the box. I welded forehand, backhand, up & down without changing the torch position. Fusion welding, no rod.

In this class, all projects come from the syllabus and instructor. So, I can't start cutting other metal, or bringing in my own stuff. He won't even let me jump ahead to the next project. Easier to teach everyone at once.
Only 14 more days in this class. Then, 2 days per week in the open lab where I can do what I want.
Already have a good sized box of aluminum and steel coupons for TIG practice. Got plenty of sheet, steel tubes the same thickness as the RZ frame, and steel pie cuts similar to expansion chamber tubing.

Also noticed at school they have a large supply of .063" 6061. I'm sure they cut it into coupons for practice. Just wondering if it would work well for a custom fuel tank.👍

Yeah, I thought of that, too. But, I wouldn't be using an O/A heating torch at home. I should learn with the tools I'll be using. I'm thinking propane or MAPP gas only.just hold the torch further away ?
stainless that's went pretty colours when welding is, as far as I know, more inclined to rust, does simply colouring it with a torch have any similar affect ?
To my knowledge, color anodizing doesn't noticeably affect corrosion resistance. When applying heat, the colors start with straw, and end with purple, then blue, then light blue. If you go past light blue, the polished metal turns dull gray. Dull gray is too far and will reduce the corrosion resistance. It can still be reversed by re-polishing off the burned oxidation. After repolishing, heat anodizing can be repeated.
Good luck, bro. I'll try to post any good tips I find.
At the last class, I still had some time. I wanted to cut a hole in my box and weld on a steel tube. Fireproof. Heavy enough to not fall over. Perfect Bottle Rocket Launcher. Thought the teacher would get a kick. Couldn't find the steel tube, though.
Was just thinking that I'll be teaching myself TIG, too. My next classes are just open lab for practice. I'd better start getting my TIG stuff ready.
Got plenty of aluminum & steel sheet coupons, steel tubes the same thickness as the RZ frame, and steel pie cuts similar to expansion chamber tubing. But, I'll try to use school materials as much as I can to recoup costs.
Already thinking about welding titanium. I'll try to talk to the instructor tomorrow to start getting info.
I'm guessing that they don't teach Ti welding at all, even in the occupational welding program, due to costs. When I mentioned Ti welding before, he said something about me buying my own coupons/supplies.
Looked around online. Only titanium coupons I could find were .040 flats and they're sold out. So, none. Plenty of pie cuts available, ready to weld, but around $10 usd EACH. Okay if I'm making something, but that's too much for practice. I'll probably buy a sheet & tube and cut my own coupons.
Tubing & pie cuts are nice, because the back purge setup is easy. For sheet/plate, I'll probably need to make a purge cup. I saw a small one for sale, I think 4" x 4" for around $300 usd. So, fuck that. Will probably need to make my own. Still won't be cheap. I think the box can be stainless, but the top might need to be perforated titanium sheet which is expensive.
I'm not talking about an argon chamber, which would be awesome, just a low profile box for the coupons to sit on top of. Could also be used for stainless, with another stainless perforated top. Even if they have a purge box at school, I'll need one to practice at home.
Thinking I should do mostly titanium and stainless welding at school, because it probably uses twice the argon vs. welding aluminum or steel.

Here's a tip I just learned. Using chill bars. Like a heat sink.

Hey Pete, take this for what it's worth, which isn't much ... 
I'm fully self taught with TIG. You saw in the build-off thread I'm welding titanium. I would say it is exactly the same as stainless with the exception that it has to be shielded for a little longer, so I just weld a few inches at a time and let the post flow cool the part before moving on. Stainless is exactly like mild steel except it has to be back purged. See what I am getting at? Once you can weld mild you can weld titanium. The only difference in feel is that titanium seems to be slightly gummy, not sure how else to explain it. The filler rod wants to stick to the puddle. It certainly could be my technique though.
Don't buy a back purge, make your own out of stainless and fill it full of stainless steel wool. You already have the machine, use it to make exactly what you need. I don't think the screen needs to be perforated titanium. The videos I watched said just don't make it out of mild since it can contaminate titanium.
I bought a pack of these, they are not long, but the price seems reasonable. 4 pcs. Titanium Ti Gr.2 Gr2 Grade 2 ASTM B265 Plate Sheet 3.5" x 1.02" x .040" | eBay
I have some cutoff and scrap pieces I'd be happy to send your way if you want some to practice on. PM me your address if so.

Thanks, my dude. Definitely appreciate any and all input!Hey Pete, take this for what it's worth, which isn't much ...
Planning on making my own back purge. Been looking at all kinds of stainless baking and utility trays. Need to find the right size, but should cost $10 - $15. Weld in a couple of pieces for the top to sit on, holes for argon tubes, etc.
Honestly, I'm sure I'll be able to weld pretty quickly. But, it's only going to allow me to tack my projects together. To do finish welding on my bikes, the beads should be very high quality. And, they all are- because they were done by Roger the master welder.
So, there is my challenge. Could I get good enough in a short time? I don't need to do every kind of welding on every kind of material, like Roger.
So for now, I'm all in. That's why I'm pushing hard & asking lots of questions. Let's see how far I get.
If I have to pay someone to do the finish welding, it's okay. If I had someone like Roger or Dimestak around, I wouldn't even think of doing the finish welding myself.
Thanks for offering up some Ti. Not quite there, yet. Where did you get the Ti tubing for your exhaust? What tool did you use to cut it?
