Ok, I thought about it and I had decieded to go with a 3" pie cutted downpipe from 2 1/2". I know everyone says its overkill, but i think it shows some talent involved in creating it. Im 17 and I have some experince (4 Months(2-3 hrs/Day).

I have a Miller Synowave 180 Sd, Gas~ 20%, 3/32 red tungsten.

Lmk What you think! Also Ill Update As I Progress.

My Equipment:




First Day:

 

Not bad....it's mild steel which looks pretty shitty welded as is. The pie cuts are o.k., but they could definitely use some work. I think it hurts it a bit because the spacing from cut to cut varies...makes it look sloppy.

The good side is your only 17, by the time your 19 you'll be bangin stuff out with the best of'em, so your ahead of the game.

So for now, not bad, not great. The pics are blurred so its really hard to see your welds enough to have any input there. Keep workin man.

 

Is that aluminized steel? It kinda looks like it, but I hope not man....

 

Actually it is, Is there anything wrong with that?

 

It'll make you woozie....

worse it can kill you from the fumes.

jealous. when i was 17, i couldn't afford a soldering iron.

 

thats why i buy mild steele now.. After reading about aluminumized steele

 

I didn't know that...but I did know that i had to get that aluminized coating off before i welded.

Thanks!!

 

solid work

 

When I weld aluminized steel, I have several fans set up to move all that air out quickly. I weld, fog the place up, then jump outside after the fans are on. It goes w/o saying I strip the coating off the 1st 1" on either side, inside and out. Usually its just the normal gases, so its more of an irritant than a toxin.

I just wish I had a nice TIG.

 

UPDATE!!!!!!DAY 2

I only had about an hour and a half to work on today....

 

Ah ****! I didnt know welding aluminized is bad.

Well, with a welding hood on and a somewhat open area it isn't going to kill you. It definitely makes you woozie though.... I woke up in the middle of the night feeling like *** the time I welded that crap.

 

Aluminized steel will not kill you. It's galvanized that can do that.

 

With all due respect to the welder, why do you people keep wasting time with pie cuts? You can buy a Donut with 360 degrees of bend. You can get any angle you need. It will cost a little more but it isn't worth the time required to make all of the pie cuts and then weld them back together.

 

I know what i couldve done, but if i have the time to make it, and make it look better than a mandrel bend...

Its a project of mine for my car and i will learn alot if i try something harder than a Mandrel bend...

Thanks for all the COMMENTS!!!

 

you always want each face of the elbow to be a TRUE PERPENDICULAR cut. Each INNER joint needs to me the CHEATED cut at the same degree each time.

 

it's okay he is only 17 his lungs can handle it.. lol.

 

UPDATE!!!! DAY 3

Well as you can see i got my tig gloves, Also i invested in getting a wire wheel, It looks better than i had expected.

 

Not bad.
Props for getting in there and just trying it.
Any welding will kill you, wear a respirator/filtration device.
"Galvanized steel is killer, but go ahead and suck fumes off of 2800 degree steel, it's good for you.."lol

 

As you can tell i got way better toward the end, Thanks for everyone commenting!!

 

I felt a little woozy after doing some aluminized. Could someone suggest something I could wear that would make it safe? I figure just a mask like you would have a doctor wear isn't going to cut it.

good job man, im just learning to weld.. my younger brother is a little older than you and took welding every year of highschool and is amazing.. I might get some steal pipe and do my downpipe this weekend like you did.

Looks like those japanese tuning shops that did all of their stuff like this.

 

Are you just welding straight on galvanized, because you need to clean off that coat before you weld.

I don't have problems after i weld, but who knows, my lungs can take it...lol

 

I got a 3" stainless vband, one 3" stainless 180, 3 feet of 3" stainles for the downpipe and the 2.5" mild steel intercooler kit + 3ft 2.5" straight from race solutions. hopefully mine turns out as good as yours.. I might have three hours of welding experience.. and it was all aluminum.
