I can lay a pretty good bead down on flat stuff, but for the hell of me I can not weld a flange to a pipe.... I can't even tac the damn thing, puts a hole right though.

The flange is 1/4 the pipe is 18 gauge. Any help would be very appreciated!! Thanks.

 

you have to go up on the pipe and down onto the flange all while not over heating the material. it takes practice, and if i were you id practice on something a lil cheaper

 

That's the wrong sequence of learning how to weld. After learning how to lay stringers on a flat piece of metal, you don't proceed to making a header.

Practice some tee joints now. See, the flange is thicker than the runner. The heat from your torch should be more concentrated on the flange than the pipe. You can't really hold the torch in the same position and maintain a nice puddle. Move the torch up and down along the seam accordingly to maintain a nice and even puddle. This is something that you'll only get down with practice. Get a hold of some cheaper material or scraps and practice some tee joints.

Thanks again for your help. This is a T joint i have done I got that pretty much down too. I guess the fact that I have never welded 2 different in thickness materials together is messing me up.

And the stuff is just a lot of old stuff I have laying around.

Thanks again.

 

After some more practice this morning...

No more holes at least

 

aim your torch at the flange...and then let the filler rod creep up the tube to weld them together when you dab.

 

man, I wonder why I can't do that "stack dime" pattern on any piece I do...I try to do a circular motion, but idk.

 

mig or tig? also, is this a turbo manifold or na header? just wondering why your using 18 guage for a manifold

It's TIG (syncrowave 200 to be exact) and it's not a manifold at all, just stuff I have around I am using to learn how to weld.

 

dam me and you are opposite. I can not make my welds look good on a flat piece but they look half decent on a round piece. Your flat piece looks nice.

 

as mentioned earlier, concentrate your arc on the flange and edge it closer to the pipe, then add filler when it starts to pool and then start moving around the pipe, but keep the majority of the arc on the thicker material.

 

Thanks a lot for all your advice guys!

That's the trick with this piece. Agreed.
