First Time Welding Aluminum

I though I would post some pictures of my first attempt at welding
Aluminum. I had allot of help from a friend. I was surprised at how
much filler I was using, is this normal for Aluminum? Seems like I had
to crank up the heat to get the puddle to flow then add lots of filler
to keep it from burning through. I kept the current just above
melting. I was using a near verticle torch position.
Materials: 3/32 plate, 1/8 Tungsten, 3/32 filler, 15lb Argon.

This is the picture of my friends bead.

I noticed mine had more heat around the weld.
I tried to do a butt weld and it came out similar but penetration was
not that great. I tried to add a little more current to increase
penetration but the width of puddle got out of control.
Feedback appreciated.
Thanks,
Dave

Re: First Time Welding Aluminum
I'm going to try the smaller tungsten and see if I can crank up the
heat and get more penetration. I was keeping the current as little as
possible because the puddle was too wide.
Maybe a little more gas and heat will help with the porosity I'm
seeing on the underside when joining two plates.
Thanks.
Re: First Time Welding Aluminum
the idea being that the ball would form at the point appropriate for the
current in use. If I want more penetration, I go slower and add filler at a
slower rate, I don't increase the amperage. No idea if that's proper, be
glad to hear some more comments.

Re: First Time Welding Aluminum
allot. I was able to slow down and got more penetration.
I was getting a little bead on the underside but it had a split going
down the middle. No matter the penetration this split was present and
would follow the seam. Also I was not able to get rid of the crud on
the backside.
I called my friend and he said "when working with alloys and
stainless, for butt welds and pipe you have to back fill with gas to
get a clean weld." Makes sense.
I still don't understand the split. Must be the crud not bonding and
then cooling.
