I am working on a 1990 Eclipse 4G63 Turbo and wanted to make my own hard pipes, so here they are. LMK what you thing, I know it's not pretty but I can just grind that down, and it is after all Flux weld.

 

Horrible, at best.

 

looks like zero penetration. Sucks ***

 

Well I am new to welding and there is penetration, you can see it from the inside. If I went any hotter it would make holes.

 

bad, I think you were trying to run a bead around the entire piece all at once which is going to happen. turn up the heat do one spot 1/4 - 3/8" long let it cool and go back around till its done. Ive seen tractors welded up in the field better looking than that

 

ok, well like I said, I am kinda teaching my self here. No one has ever shown me how to do this. So I need to do a weld 1/4-3/8, should that be all spot welds? Then when the first one cools I should keep going till I get all the way around?

 

you can;t get defensive man you asked us to rate your weld. Your wirespeed is too fast or you have too little heat. Either heat up or slow down. and are you pushing or pulling the gun?

 

I do alot of flux work, some help/pointers would be great....instead of the typical you suck replies...

No, I'm not at all. It's hard to tell how someone is being when your typing.
I am pulling, and I think your right I may need to heat it up. I did start going side ways there a little so that is where some of the worst welds are. I'll take all the help I can get. Maybe one day I will mig, but for now this does the trick. I can always grind it down and it will look fine.

 

Flux sucks... Get some gas... much better, cleaner welds

Thats a false statement. Any weld sucks if you don't know what your doing, and you have a shitty machine.

 

Holy splatter batman, keep it closer.

 

I used some spalter spray and that helped a little but I was told with Flux there is not much you can do.

 

that thing will leak!

Is it stainless, don't get penetration confused with surge, I believe its called. Almost looks like boogers, well thats what people describe it as. Cut a piece in half to see how much penetration you are getting. Even though on that piece, penetration is not that big of a concern.

 

I checked it with a light in the dark to see if there was any light shining through, and there was not. I had to make all that even the holder, so I was thinking it was not that bad, but maybe it is.

It is mild steel, I am welding Flux and I was told you can't weld stainless with Flux?

I think I am going to try turning up the heat because I am getting that popping sound, but like I said when I do I burn though. I guess I need to go faster, or just use tacks welds.

I am also not sure of the thickness of the metal sometimes and I know that is what matters when turning up the heat.

That'd be 'sugar' or to be technical... carbide precipitation.

 

put some water i it and close the flange somehow. i'm sure it will leak

 

I also welded the inside too, but I'll try just for you and see what happens.

 

i have a flux core welder and thats what my firsts welds looked like. i would sugguest starting on a thick piece of steel that you wont burn through and work on laying a good consistnant bead. then try welding 2 pieces together 90 degree style to figure out the correct wire speed for you. the amount of heat you will only learn with experience. work on getting good clean even beads before trying something round like you did. and always have a clean surface that is super importaint even if you get better a crappy surface wil make your welds bad.

Thank you, that is the kinda of help I am looking for. I'll give that a try.

 

keep the welder on the thicker piece longer, then just quickly weld it to the thin piece..

keeps from blowing through the thinner piece.

 

What were your settings by the way? Like wire speed and voltage (maybe yours just has HI/LO?)

Also I haven't flux cored yet, but what kind of wire are you using. Even stick welding wouldn't look that rough, so flux has the capability to look good.

The biggest problem I see is that the weld is kind of just sitting on the surface instead of fusing into the base metal. It will have strength because of some fusion and surface tension. But when the motor and exhaust start yanking on that thing day in and day out and you combine hot exhaust gases, I wouldn't trust that in the long term.

Plus you owe it to yourself to improve your skills....don't settle, get good at what you do.

 

I'm sorry if my answer didnt please you, but you did ask how it looks like and I said it looks like theres no penetration. But you can really see that with your own eyes, you laid a tall bead that sticks out. its sort of like a circle, the point where its fused isnt as big as you'd think. Grind that off, turn up the amperage and then slow the wirespeed a bit.
Also welding pipes with spot welds is ok, I did IC piping like that and I pressure tested them that they dont leak.
