Yea..........................................you need some practice tig welding aluminum. Your welds look like someone blew their nose and snot came out and stuck to your metal. Don't expect it over night. It's going some time. Did you weld it on AC with argon gas?
|
Welds were done with AC and Argon.
Yeah man, the square stock and angle stock came out good enough, it penetrated. The flat stock was atrocious. End of the day, it was still worth a try. It 100 percent makes me appreciate good welds. It's an art. Sent from my SM-G975U using Tapatalk |

For aluminum. I use a mig gun at home. I have a Lincoln 180 Pro with the aluminum mig gun. I want a Lincoln Precision TIG 225 with a water cooled torch. Welding aluminum, the torch gets FVCKIN' HOT! |

Wow, I found out why my last welds went from bad to impossible. The argon gas ran out... So yeah, that was a problem. I was getting so pissed at the end because I kept taking off the part, cleaning the metal, cleaning the tungsten, lightly grinding the metal and putting it back on just to keep shooting Zeus's lighting bolts at the flat stock murdering what I had JUST cleaned up.
The more you know. ORB fittings for the valve breathers were at the shop for over a week. Pretty cool... Those were put on and it was very gratifying, and it was such a simple thing too. Probably because the breather system is a completed system where as everything else is in the middle of incomplete. Best part was, that it was really simple to do. I needed that. Easy wins are welcomed every now and then. After that, the arts and crafts has begun for the air box. I'm starting with paper because it's cheap and easy. The sheets of aluminum I bought were 30 dollars a piece... maybe 25. Something like that. Point being... I don't feel like buying a whole bunch due to mistakes OR trying to flatten out a mistake. After everything is cut to shape (and figured out), the aluminum sheet will go on the underside of the flat stock. I'll then drill holes and rivet the aluminum together. The sides of the box will be held down with threaded rivets and screws. Well... that's what I'm thinking so far. Sometimes things change as I'm doing it. https://b55dag.dm.files.1drv.com/y4m...&cropmode=none https://b55gag.dm.files.1drv.com/y4m...&cropmode=none https://b55eag.dm.files.1drv.com/y4m...&cropmode=none https://b55bag.dm.files.1drv.com/y4m...&cropmode=none https://cj5gag.dm.files.1drv.com/y4m...&cropmode=none https://cj5fag.dm.files.1drv.com/y4m...&cropmode=none https://cj5iag.dm.files.1drv.com/y4m...&cropmode=none |
Metal gets $$$$$$ quick. Try pricing a sheet of 8'x4', 12ga. 316, 2B stainless..................$800.00. Someone wants me to do a project for them. Once I add up the material. I think they will change they mind.

To add a comment to the aluminum welding. The running out of argon will definitly make a difference, but It looks like you are also doing a horrible job on cleaning the part. There's the stock stickers still on some of the pieces and adhesive under one of the welds. You need to actually clean it, with a wirebrush or abrasive that has not been used on stainless or mild steel. Then you need to scrub it with acetone or some type of aluminum degreaser.
It also looks like you are using too large of a filler wire maybe. Thats the only thing I can come up with for those globs. For aluminum the filler should basically be melted and jump to the puddle, if you are having to plunge it into the puddle you have too large of a filler. |

My need of getting it done way out paced my skill set there. I'm ok with the glob welds considering where the bar is located. I think I'm going to cut the flat stock off and re do the section from the front of the radiator to the angle stock. Honestly, It's all learning to me and there have certainly been lessons learned. I'll get there, it just will be a bit painful off the get. The good news is that the aluminum stock used there wasn't terrible expensive. Thanks for the feed back man! Good to see a new name on the thread. |
Also when wire brushing aluminum. Use a stainless steel wire brush. Use it for aluminum only. If you use a carbon steel brush. It will leave rust marks in the aluminum after a few days. If you use a stainless steel brush that has been used on a different metal. It too will leave rust marks. The particles from the brush will imbed into the aluminum. That what causes the rust.

Re-do on the box frame. Used new aluminum that is wider and actually cleaned it properly with acetone this time. Most importantly, the weld was done with a full tank of argon as apposed to the tank running out. I couldn't figure out why my welds were not working at all last time. The more you know. ---------------------------------------------------------- https://cj5bag.dm.files.1drv.com/y4m...&cropmode=none https://cj5cag.dm.files.1drv.com/y4m...&cropmode=none https://cj4qag.dm.files.1drv.com/y4m...&cropmode=none https://cj5aag.dm.files.1drv.com/y4m...&cropmode=none https://bz5hag.dm.files.1drv.com/y4m...&cropmode=none |
I can't say last night was incredible productive. As always, something is better than nothing. I put the front clip on to get some measurements of the bottom of the tray and transferred the dimension to paper. Seeing the paper stock on the car helps visually so much. The paper cut out ended up being exactly the right measurement to the bottom of the bumper; but, I noticed rivnuts can be used to fasten the sheet if I extend the aluminum/paper 1". Actually, I may extend it a bit more than that so I can fold the metal back onto its self for strength. .... I need to look that up to see if that's a thing.
For grins, the A2W intercoolers were set in the position to mate up with the turbos and intake plenum. They fit perfectly there as an option. I might angle them upwards towards the plenum later. The big deal here is that there are options. TBH, I kind of like them flat. https://bp5dag.dm.files.1drv.com/y4m...&cropmode=none https://bp5fag.dm.files.1drv.com/y4m...&cropmode=none https://bp5cag.dm.files.1drv.com/y4m...&cropmode=none https://bp5bag.dm.files.1drv.com/y4m...&cropmode=none https://bp4qag.dm.files.1drv.com/y4m...&cropmode=none https://bp5aag.dm.files.1drv.com/y4m...&cropmode=none https://a55hag.dm.files.1drv.com/y4m...&cropmode=none |
Coming along :tup:
You gonna mount your water tank in the rear & plumb 3/4-1” cooler lines Up & through the intercooler? :ugh2: |
Yup. Water pump, 1" hose, heat exchanger and fill will all be in the rear. My buddy did the same thing on his car with zero issues. Besides, the front is getting cramped.
