or we could just add them here. I registered on there and plan to discuss all my fabrication work there as well as here. While I would love a fabrication forum on here I can't fault the admins for doing what they do. It is afterall not a democracy. I would venture to say that perhaps some of the higher ups on here also think it is a good idea but say no based on principle and for good reason. Can you imagine what would happen if all you had to do was complain over and over to get what you want?

I understand that. I was thinking more of a branch of the Tech forum or the Forced Induction forum. Kind of like other websites have a "Not Work Safe" sub-section as part of their picture forums.

 

as far as a fab. forum... as in welding.. just fabrication in general.

IE. the aluminum lic. plate brackets... basicly a sheet of alum bent 90degree to hold a lic. plate..? thats fabrication.. and a forum for that DIY, or discusion would be wonderful.

im sure someone one day would love to create something? maybe a new tripod stand for a onboard camera for a drag race.. great fab topic.. you get the picture..

Right, I don't think any of us advocating this are looking for something specific. More of anything that falls under the genre to be in one place. In any case it doesn't seem to be happening so hooray for http://www.fab-forum.com

Understood. Back to welding, I just had some stuff welded for a school project by this guy who is a sick aluminum welder. It's pretty much all he does for the whole day from what I understand. I should be picking up everything tomorrow, so I'll get some pictures of it. I can't weld for **** right now, and we definitely needed strong welds for the project.

what kind of project is it, that you need strong welds.. but use aluminum? wouldn't steel be stronger? or keeping the weight down?

now im interested in this project.

Right now we're using 5/8" aluminum rods with around 0.075" wall thickness, but we'd like to find a stainless steel rod with comparable strength, less overall weight if possible and smaller outside diameter. I keep mentioning titanium but nobody takes me seriously. We used aluminum on the prototype because our advisor thought steel would be too heavy. The two biggest priorities are keeping the weight down (the whole thing has to float) and maintaining maximum strength.

EDIT: Heres the pictures. Some of the pictures of the welds didn't come out that great (stupid flash) but you can see a little of them. I have some other stuck at home like my oil pan that the same guy also welded.

well yall might rember me from earlier on this post (i am more comenly known on homemadeturbo.com for my manifolds and flanges), i ended up buying a miller syncrowave 180sd tig and have had it for a little over 2 weeks now. well i am finially starting to make really nice welds. here are a couple pics of a half done stainless steel log manifold for a d series i am working on right now. rember i am only 17 and i am pumping out these welds.

Constructive critism to bmc racing -

Good welds if you just started tig'ing a couple weeks ago. There is a lot of undercut on the flange though (also on the outer two pipes connecting to the inner two where they face the flange). My guess is - wrong torch angle, too much heat, or too long of arc length (bigger puddle). Tig'ing takes a bunch of practice. Good luck.

i agree. too much heat, not enough filler. im sure if you try to bolt your flange up to a head its not gonna fit ,.

 

Any tips for mig welding stainless pipe to mild steel flanges?
I am using 309 wire with 75/25 mix gas.

also the wire keeps getting stuck to the contact tip, am i using too much power or am i just welding too close.

 

i had mine stuck a few times (wire in tip on MIG) i think thats from getting too close.

im gone for a day or two and this thread got like 2 pages longer in no time.

Got a Miller maxstar 200 dx cool little machine ill let you guy know how it goes, im going to be getting a 220 in the garage this weekend. Ill also be using the 110 in my fab-shed since this Tig welder can use that also, kinda cool, its also like 37lbs, has this little strap on it so iv been carring it all around like its cool or something. haha

still didnt tell me what the hell your making... lol

 

well im tring to get my setup to work good but the welds dont look to good, i want them pretty...

miller maxstar 200dx
3/32 tug
75/25
this was at maybe 60-70amps

use ARGON!!

you use pure argon for pretty much everything when Tig welding. I would say that is your problem if that's what you mean by 75/25. Also higher flow rates at the torch don't mean better shielding you can acutally end up drawing air into the gas flow if it is moving too fast. In a calm environment you can turn your flow down, I use around 12 cfh when welding inside. How thick are those elbows? 60-70 amps won't cut it if they are schedule 40. You should be using approx 1 amp per .001" of thickness of the material you are welding.

use a tri mix for anything to do with stainless....it'll turn out better. I've gotten away with 304 to mild steel with 75/25, but it will turn out better with tri-mix

 

what mix is that tri mix..

ya i seen on my little Miller calculator is said argon but i thought sheilding gas was sheilding gas.. i was soo wrong, with argon it looks great! thanks

and with that ratio of .001 = 1 amp i think 1/8 (close to sch 40) i might want to try around 125 amps... im at 90amps now and it works great, and its only on a 110v line. I love my miller maxstar thanks again you guys

 

is it recommended to use filler or not... like when there is no gap or butt weld to butt weld? to use filler or not to use filler, that is the question?

 

keep this up. some loser tried to start a 'newer welding thread'.

I was reffering to Matt B...lol

you need straight argon

 

tri mix is 90 percent helium/8 percent argon/2 percent CO2 right?

 

hey welding ppl how thich in inches is the 40 sch piping from mcmaster.com? trying to figure this out before it comes in so i can set the welder using some of the same thickness steel

 

close to if not 1/8" in thickness

 

it says when you order. each size as in I.D is a different wall thickness. theres also a chart on mcmaster.
heres dug it up for you.
http://www.mcmaster.com/param/html/Schedule/

 

Not sure if im soppose to ask or put this in this furom but,
Are there any good and clean welders in washington that i can get my stuff welded and junk. will pay for helping.
Thanks, Please PM about it, dont really keep up with this posts. thanks
