critique my welds!

[punkfreerider]

Every morning when i go into work i lay a couple warm up/practice beads on a couple pieces of scrap, I brought one of them home the other day, and figured id post a couple pics so you guys could critique them! so lay it on...whats right/wrong with it? haha

heres a couple more...fyi...my goal with these welds is to have no bleed through whatsoever...most of what im welding is parts that go on the inside of an oil pan, so having bleed through isnt acceptable for asthetic reasons, and its all TIG

What are your settings? Gas flow, amperage, tungsten size, filler size, etc etc?

I won't say I'm the greatest expert, but if I had to critique, I'd say your filler wire is a lil thick for the heat you're running on that thin material.

gas flow is at 15 cfh, i believe, but im not sure, tungsten size is 3/32 thoriated, i set the machine at 135 amps and do the rest with my foot

hey thanks though! i appreciate the input

The pics look pretty good; if there were one thing I would do a bit, it would be to do your dips more frequently. The beads are spaced a bit far apart. They can be smoother with closer dabs, and maybe less pedal pumping, and more constant dabbing of filler. It will also help the slight undercut you have in a few spots.

Other than that, it's going decently.

looks like your torch angle is off, thats why there is more metal deposited on one side of the puddle. Also seems like your moving really fast. Turn your heat down and move slower.

I would have to agree with most of what has been said so far. Smaller filler rod, dipped more often, and fix your electrode/torch angle so the top doesn't get undercut.
Not sure I would turn it down, the smaller filler rod will force you to speed up.
If that's 11ga plate, then anywhere form 120-130 is what I would usually run.
I'd be using 1/16" filler to make it look a little nicer to the eyes.
It also looks like your filler rod hand is the unsteady one, make sure you cut the rod in 1/2 before starting to give better control. Make sure you are adding filler as close to parallel to the bead as possible. If you run a few practice beads everyday, stack up the week's worth of trying different settings and hand positions etc, and destructive test them on friday after work.
Lets you know what is working on the outside and the inside.:drinkup:

weld looks good, but i think the end of the weld is a little weak and sloppy looking, should end as good or better than the rest of the weld, but the end looked a little thin

SINNER!

This spot welding (stacking the dimes) does my head in. Your working with metal when it's fluid, so make the weld look more fluid.
