need help trying to find tial wg install pics
Hi guys
Does anybody remember seeing a tial 38mm waste gate being installed on a TII manifold? the thread had pics of the doing, can't seem to find it anymore or maybe it was on an other forum? can't remember
can anybody help me in finding this? even if it was not here you maybe saw it somewhere thank's
j-p

Was it like welded to the stock manifold??
there were a couple For Sale threads that I saw something like that done.
one was by JUST STARTIN(?name on forum).

the guys name is JUST STARTN ..no I...sorry about that.
.Also FS_WTB(Clem) had some sort of Turbo that looked like it had a wastegate Welded to the Stock manifold.(Cdn For sale Section)
...OH,by the way.If you are looking for a T4 Manifold,I have a Good one..and it won't Kill your Wallet..Pm me if interested!

welding cast metal can be difficult. great chance of the weld cracking. if you attempt it, use lots of heats and use a fire blanket to let it cool down as slow as possible. good luck.

TIG or Stick, MIG isn't the best process for Cast welding. PraxAir, or any other welding supply store should be able to point you in the right direction for the proper weld consumables.

Don't listen to this, you'll end up with cracks galore after the first heat cycle. 304L stainless has the closest thermal expansion rate to cast iron. eg: it will move WITH the casting.. Nickel has a thermal expansion rate that more then 10x less then cast iron. eg: it WILL NOT move with the casting..

really? your info is contrary to EVERY welding forum and info page on the internets.
I rewelded my v-band back onto my cast iron snail and raced on it for the second half of the season and it's still on there just fine.
I used nickle rod pre-heating the cast iron to 700*f and buried it in sand to let cool slowly. my only flaw is using 1/8 rod instead of 3/16, spent a lot if time chipping the flux off so i could see the metal and continue welding.

If you go to this one you can see the only selectable option for welding Cast Iron is Ni-CL...

If your nuclear plant design engineers thinks that cast iron and nickel have have the same thermal expansion rates then yes, good luck living next to the china syndrome.. this is basic materials science.
I've had welding 'instructors' come through my shop looking to do some TIG welding on some less common materials.. I wouldn't be overly proud of having an Ontario welding certification..
..why did I just know you were a Union git.
and your first link supports my comments regarding Ni being unsuitable; they use/sell a proprietary rod mix that elongates 300% more then std. nickel rod, for the very reasons I mentioned.
I've been using stainless rod on air cooled engines for aircraft for a long time, engines that stay running at 75-100% max output for hr's on end.. never had a crack occur because of a weld, you may see fit to use a material that is very unsuited to cast iron.. I'll stick with a material that has similar properties..

As a Union Millwright welder, I have NO idea how to weld I guess... Carry on, and prove me wrong. I guess the Nuclear Plant I'm helping rebuild will crack and crumble...

look at the down pipe that doesnt look stock at all maybe a setup like that would work?

Because you are oh so smart.

Yeah if these instructors aren't CWB/AWS certified that means ****, I'm sure you don't share these same certificates either. There is no such thing as an Ontario Welding certificate... It's all Mandated by the CWB in Canada, and AWS in the US, and TSSA for anything containing more than 15psi.

Yeah it does supports it, I posted it because he's trying to sell HIS own product, he would be a moron not to try pushing his own wonder material, it would be like you saying your butt plugs are the best, and not using it on a daily basis, I'm pretty sure everyone knows you have something stuck up there anywho.
Good for you, I am happy for you I really am, how are the 4 rotors you brag about coming along, we still haven't seen any pictures of them.
For your edification, ( only don't tell the other union kids, they may get mad that you know something outside of the dictated union parameters..) 304L rod HAS nickel in it, the reason you want 'some' nickel is that it's one of the few elements that permeates the cast iron crystalline structure to bond with it. Pure nickel rod or even the rod that Lincoln sells for blocks and various engine repairs is not suited to rotary or turbo exhaust housings given the extreme heat levels they see compared to a relatively cool V8 block.
However I do think that muggyweld rod is worth some more investigation.

Doridori People have welded cast iron Syritis is one of them why would you come and argue what it says in a book? Just because you say it's wrong doesn't mean it actually is
I'm pretty sure i saw the guy demoing his welding rod on an exhaust manifold.. may be it was a v8 block i could be mistaken
why are you harping about the guy because he is in a Union? That's pretty disrespectful when you don't even know the guy

the reason you use nickle is not because it isn't expansion rate, but b/c as far as metals go nickle is fairly soft and allows metals to expand at their own rates. ie joining a cast iron turbo to a stainless steal v-band. this is my understanding based on my own experiences, hundreds of other people experience and a couple welding instructors at SAIT.
i just remembered that i have a spare turbo hot side sitting in the garage with a broken off v-band, I know it's not arc welded and not being a certified metallurgist i couldn't tell you exactly what the welding filler is, but it's definitely not soft like nickle.

bwek; where did I say you can't weld cast iron, you can, I do it all the time, my argument is based around the recommendation of a ' pure' nickel rod.
You obviously didn't understand the point I was trying to get across to you about the wheel. In the most literal sense it can be fixed, what I was trying to tell you is the wheel will be, at very least in the area around the repairs, softer then a cast wheel.
buggy; I guess you should stay away from posts that require a modicum of thought, best go watch ' The Hills'..
