Was it really necessary to weld the inside? Seems like more hassle than just working on penetrating more. Just my 2 cents.
650 for what? there are pin holes all over the edges of your welds on the plenum floor plate at the runners. your welds are cold. there are sharp edges on every transition on the inside. i wouldn't pay more than $50 for that so i could cut the head flange off it and start over.
- Please take one of the pics and circle the pin holes, because I don't see any. maybe I am missing something?
- only cold welds would be the one inch spot in the center where the 3 edged met at the T.. and that was a second pass cover because I had ****ty fitment at that point. The rest are 185 amps, 350+ temp on the entire manifold, if anything the beads are too wide and spaced, I somewhat rushed my work I will admit it on this one. You photobucked failed on the other few posts I saw you made so i cant see any more of your work... but http://forums.vwvortex.com/showthrea...nifold-i-built from the far away pics your welds are just about the same as mine. Mine like i said on this are a little farther spaced, but not cold all over the place. I would trust this thing up to 60psi easy.
- Sharp edges on the transition inside? again I must be missing something, kindly point that out too. The runner entrances are smooth, see bellow for another pic. The only sharp transition edge is the TB plate bore dumping into the plenum... not much I can do about that.
not even going to fight back on the $50 comment.
nice work TIGNinja... did you bend that on a break yourself? what thickness material?
that stepped one looks cool, but i would think with the drop down on each step its going to create a circle of air falling off it, just looks rather turbulent in there thats all. air flow doesn't like edges bends or steep drops.
what do you use for ac settings for 1/8th if you dont mind sharing? I usually crank the freq up high to keep a stable arc no pulse and about 28% cleaning, 3/32 #8 gas lenses gold tungsten around 125 amps about continuous the whole time.
Yea about 125 amps. I use regular cups for aluminum and usually whatever size is closest to the machine im using (im lazy ). As far as settings goes I dont really care. Whatever the machine is set at
I know all the welding nerds think there is some sort of magical machine setting for everything but if you know how to weld it will turn out good no matter what the machine is set at.
totally a left field question, but is there any particular reason nobody smooths the welds on their custom manifolds? I'm not aluminum fabricator by any means, but that's the first thing I did with mine. but that's probably because my car will never be fast, so I make it pretty instead.
