those collectors are pretty trick.

turbob16ef · 12-21-2013, 10:53 PM

Just ordered the ahp alpha. Hopefully a decent first tig/welder. Welded couple things, exhausts, diffs, random bits with Lincoln mig, with no argon. Really shitty. Lol. Hopefully will use this alot more, with argon. Lol.
Pretty much bought it for future employment and finishing up my car.

Will add some pics when I get it up and running.

You welded with no shielding gas? I really hope nothing structural, I wouldn't want spongea holding my stuff together. But good luck with your ventures with tig welding.

i really hope it was at the very least flux core.

The ahp is an awesome machine, good features much better choice than the Eastwood or other comparable tig welders in that price range. If you can't get a miller or htp than the ahp is a good choice. I love the damn thing

1 1/4" piping with .120 wall (easy to work with but its all I have currently because its normally the only piping I work with.

In this photo, there is some blue on the weld which caught me off guard. These photos were taken by the end of the day so a lot of times I was trying to figure out how I got the blue in the weld but couldn't replicate it. Couldn't find anything online either, there isn't much information online for tig welding without everything going off subject or covering a hint of something.

At the beginning of this one, forgot to turn on gas and started with too much angle on accident. Clumsy.

Looking good taunt!!!!!

turbob16ef · 12-22-2013, 08:05 AM

Yes was using fluxcore. But still was pretty shitty. And no nothing at all structural. Other than I guess the diff. I didn't use it that often and always just asked my neighbor to weld anything I was sketchy of. And I was just to cheap to buy/rent a tank of gas.

I have heard alot of good reviews with the alpha. And once it's in possession I will be taking my time with that and the mig. With gas.

Yes gas is a must 100% argon for the tig

I know that. Was more just stating because of what I said with the mig.
Hopefully within the next couple days I will have some pics of my new project(s).

using a filler thats too big will cause all sorts of issues. plus you can't get your tungsten close enough to get any good arc focus so your haz will be huge and zero penetration.

Like the idea of that Tee fitting on the wastegate tube, looks pretty good, wonder if it'll flow enough to keep that turbo in check.

I appreciate the tip. Very helpfull. Just had time to pick up 1/16 filler and seems to work out a lot better.

I would appreciate some comments on this manifold, praise or criticism. It was not welded by me

GabeS14 · 12-24-2013, 04:29 PM

I dont like the welds between each piping, but I am not a fabricator just an admirer of the work on this thread...

That almost looks worse then that 500pnd piece of shit sidewinder RB2X manifold that one guy made awhile back. If that answers your question.... Would love to see the inside of those runners. Prolly looks like a coral reef.

aga · 12-25-2013, 03:20 AM

i also am not a welder, but i gotta ask the knowledgable people in this thread, welding along the runners like that doesnt it make it prone to cracking?

ultimateforce · 12-25-2013, 10:23 AM

It makes it prone to being a piece of junk.

McRussellPants · 12-25-2013, 04:17 PM

What a mess

also lol at that egt bung on number one.

ultimateforce · 12-25-2013, 05:29 PM

I think that would be number 6, which on RBs is the cylinder that goes lean and gets the hottest.

Edit: Just another reason why V8s are better.

McRussellPants · 12-25-2013, 07:55 PM

That's a bottom mount? Wastegate top punching a hole through the hood. Haha.

codyace · 12-25-2013, 08:02 PM

The welds along each runner are what scare me the most there. Yikes!

Slims · 12-29-2013, 12:11 PM

Hey guys, i have a project going and wanted a little advice from a seasoned fabricator.
below is a new frame rails i sectioned in and im looking to support the joints. Fishplates were my only idea, but since all of the joints are at a bend im not sure if it will provide it with adequate support. I've also seen debates on which surface the plates would provide the most support (top/bott-sides) i always assumed the sides were the general rule. the only reason i bring this up is because the only good, somewhat straight joint surface i have are on the top and bottom. thanks for the input.

ultimateforce · 01-15-2014, 07:50 PM

Just some dump tubes for our turbo kits we make in-house. Nothin' special.

ka-titties · 01-16-2014, 01:30 PM

das purty.

how do you do such a long weld on a pipe like that without stopping?

unwtdhero · 01-16-2014, 02:03 PM

Rotating table^

runners are all supposed to be equal in length. That's why they have to be bent and curve all "snaked" around each other for the single reason of all the runner being equal to one anothers length. Those welds along each runner has heat hardened the steel as well and will result in it being brittle which is prone to cracking like someone previously said above. Only car I know of top of my head that doesn't have equal length headers is are subaru's boxer engines. Honestly idk why they aren't equal and i don't know why they would want so much turbulence in the exhaust flow. Must be something to do with those flatties.

Who is down to build this full wrap around drift bash bar ??

Sounds like you don't know much in general, most stock manifolds are not equal length, SR20/Evo4G63/DSM4G63/SRT4 manifolds are all unequal length and tend to produce more TQ down low than equal length manifolds. Even a number of aftermarket manifolds are not equal length, such as the Tomei SR20 and KA24 manifolds.

kingston240 · 01-16-2014, 07:59 PM

Cool idea.

I will likely use that!

tauntdevil · 01-16-2014, 08:08 PM

If you have a spare house fan, put a controller in between the wires and a plug, then place a plate on the top of it so you can control the speed it spins at and weld on it.
