Oxy Acetylene welding..Good for exhaust/charge pipe work? Manifolds??

Oxy Acetylene welding..Good for exhaust/charge pipe work? Manifolds??
Ok well my neighbors got an oxy acetylene torch laying in his garage it's just taking up space. I was talking to him and he's only asking 65 bucks for it. It sounded like a good deal and I'm thinking about picking it up.. I know you can do brazing/heavy soldering with one..It's possible to use one for exhaust work and for charge piping too? I'm guessing it's not adequate for manifold work though? I've been researching welding ALOT but have zero hands on experience with it. (Well maybe in 8th grade shop class 6 years ago)..
Sound like a good deal? I think the tanks are filled.. Anyone have input?

torch with full tanks $65 bucks is a good deal... even if you don't use it for welding. you can do everything with oxyacetylene. it just won't turn out as pretty and as strong as mig or tig.
if you're a low budget do-it-yourselfer, oxyacetylene is cool.

I wouldnt trust brazing to anything that physically needs to be strong, or that has some fuction with heat. A&O is good for cutting metal and making metal maluable... thats about it.

Thats what I (thunk) but they were asking so I figured I would to

"I wouldnt trust brazing to anything that physically needs to be strong"
actually, brazing is quite strong. A lot of brazements have a higher tensile strength then the base metal, so for mild steel or whatever its just fine (not for high temp though). I've seen a car transporter with the 2nd level car racks (inside a semi truck type for race team) all brazed.

oxy / gas welding is not bad at all and for someone who can gas weld when it comes time to tig it will be so easy you can gas weld just about anything like exhaust chargepipes ect and when you get good at it it will look like tig welds

So are you saying it is the same techniqe as Tig welding? Cause im pretty damn good at brazing silver soder. once every 10-15 times i will find a leak. So what will i need to use to weld with my A&O torches? Welding rods?

Im taking a gas course @ a local welding school. taking the course as a prelude to A comprehensive TIG course. Im doing 45 hours of oxy acetylene welding before i move onto tig..Im about 20 hours into the course and can lay some beads that my friends though were tig welds . A few of the pieces i welded together really came out nice looking. I can't wait to move onto tig (never touched a tig welder before ). Should it be alot easier to pickup now that im able to gas weld easily?

Well maybe you can answer my question. What do I use to weld with?

Re: (eLUDEnu)
A&O and TIG have some similair processes and ways to manipulate, but arent "if you can do one, than you can do the other"... but they're related.
Brazing having high tensil strength can only go so far. Tubular steel has higher tinsel strength than solid steel stock... but the tube will crush when a peice of stock will bend. (just making a point)
Brazing should (in my opinion) left as a last ditch fix until a prper weld can be done.
Brazing isnt physically bonding the two metals together, its a "glue" so to speak. With MIG, TIG, etc, you're getting the two to fuse together.

Re: (SJcivic)
I don't know the name of the thread, I think it's the old welding thread from the tech forum, there's some pics of some good gas welding. Oxyacetylene welding is perfectly strong and capable imo, just not maybe as fast or as easy as using a mig for example. If you're good with the torch and you can get both metals you're joining and the rod all liquid real nice like, don't worry about anyone saying it won't hold up to the heat, isn't strong enough, etc...
You need anything that will work as a filler rod (the same or higher grade metal) and maybe a different tip / torch if you only have a cutting torch. Good luck
