Practice

[camdigger]

I did a small job a couple weeks ago, and it was bitterly obvious I needed more practice.

I cut some coupons out of 1/4" x 3" and did some open root multi pass welds. 1/8" 6010 root, 3/32" 7018 fill and cap. Flat position. 3/32" land, 1/8" gap. More practice required.....

Might use a narrower gap next round. Like 3/32".

Some of them look like my bad days.I quit and come back later .

When you come here next week, let's go to the shop and try something.

Sounds like the sandbox will see some action!

Up the amps and run it faster. If you're not already doing it... push, so can see where you're going.

I am actually more concerned with the root than the cap. With the settings and root factors, I had trouble controlling the keyhole. That would need a narrower gap, or less amps, not more.

Watched a Weld.com video again. They were using a narrower gap and smaller land with the same rod size and type with similar amperage (1/8" 6010 at 90 amps). That might be this afternoon's project.

Still not perfect, but a lot better. Reinforcement on root and cap both less than 1/8", so should be within spec. Seems a bit rough coming off and running onto the tacks. I need to feather them better.

Not sure what caused the porosity in the cap. Could be moisture in the rods as I do not have a rod oven and the rods are over a year old.

Much better now.

Looks like some quality rust pitted steel from the inventory pile! May be getting some issues from that too.

That and not cleaning up the surrounding area of rust and mill scale. It's pretty forgiving, but that looks like it could have contributed. Of course it could just be the photo though. I have rod that is several years old, and has been wet, it doesn't usually cause a (visible) problem.
