Some info before viewing: Sync 200, 1/16th red tungsten w/ gas lens, no pulse, around 100-130 amps. Plz comment / critique















Here's an exhaust I'm almost finished with, hard to see since all pics were taken with a camera phone..

 

The beads are quite consistant.
The colour is a bit mixed and charred from start/stops.
Overall,very nice I think.
The melting of the flange on the underside looks like fit-up,
but it may have served you better to let-up a bit there on the heat.
Only thing I would ask is if there was a groove there on the
pipe attaching ot the flange?
If there was fine, if not, the welds are a little concave.
Easy fix though, just feed a little more filler into the puddle
each time.
Exhaust looks cool...

 

I like it.... can you show some pics from the back side.

 

alittle undercutting, i would run a second bead.

yeah it's not so much fit up but since the ports are oval I just punch out the material and it has a tendency to seperate from the flange leaving a small gap to fill.

 

you need to clean the metal and prep it alot more. Run a wire wheel over it all and some good cleaner before welding.

 

yeah definitely clean it better.

Also, the black sootie areas with orange in some of the pics usually mean a contaminated tungsten. Did you accidentally hit the puddle with the tungsten and keep going? That black area is definitely contaminated.

Your consistency is pretty good though...couple little things to address and it'll be baller status.

Thanks! Yeah I usually end up forgetting to prep everything 100% until it's too late lol. I'm working on my aluminum right now, it's getting pretty good, but not as good as my brother I'll try to find some pics of that too.


Here's a couple more pics of my friend Tim's recent work! It's an E36 M3 I believe.

 

that look FUC*ING miserable to make!!!!!!!!!!!1

 

Doesn't look bad at all...push more filler in though.

 

what filler is being used?

 

Whats undercutting?




Is this a 6-3-2-1?

 

1/16th 308L I should be using 309L though.

 

undercut is at the edge of the bead where it looks like some material is missing.
caused by too much heat or not enough filler.
