  • Which is best ?

    My project [ turbo / hybrid] requires I fab my own mild steel headers from flanges and pipe kit. I have two,well actually three options, a stick welder, a wire feed or an oxy/ acetylene . I had a introd. course many yrs ago but feel confident I can do this with a little practice. Which would you prefer the wire feed or the oxy and why ?

      MIG them then grind them down/pressure test.

      That is if you can't get a hold of a TIG.

      Stick would make a mess of it and I don't think you'd get a good enough weld out of gas.

        Yeah, I'm thinking the little wire feed might be the ticket.I will have to set it up and start practicing on some scrap exhaust pipe.

          I would and did gas weld mine. Why would anyone want to do a lot of unnecessary grinding? The only exception would be the weld to the header flanges. Bevel the flanges for the tubes from the gasket side of the flange. Either mig or stick weld the tubes to the flanges in the beveled area. Then face the flange gasket surface on a belt sander.

            Mig expsecially if its a real gas and not a influx wire core. Its easiest and works the best imo unless you have access to a tig welder and can use that.

              So mig if I have the shielding gas,which I do,or oxy / acetylene if I want a smooth weld ? Thanks guys, since I'm gonna have to do some practicing on scrap pipe I'll give both a try, I may find that I prefer one over the other !

                I've done lots with flux core, they usually turn out good after a little grinding.

                  I've been thinking of mig welding up some header for my firebird I just have a flux core lil linkon but would it help (because there is no gas hook up) if I used a separate gas tank and fed that into the capped off header as I welded or is it worth it I've wanted to make some for a while now but I've been waiting till I can get a tig and practice a bit but thats not happening this year so I wanted to just make some bs headers for now till I turbo it later
