Here is something to try. Just like you would do a lay-wire on carbon try it on some Aluminum. I have never heard of anyone doing this. For fun I was playing around with this new 4943 and was trying to lay-wire. It actually worked fairly well. Anyone ever done this before or used it for some specific purpose?

I was just trying it the other day as some practice on 1/8in aluminum doing some fillet welds. I did notice if I didn't push it in hard enough it would melt the rod back farther than I liked.

i use it all the time on build up on castings. obviously it has to be really clean for this to work. i find a weave pattern works best.

Off topic;
Do pipe welders weld aluminum with an open root?
We used copper plate backing on a push pull gun for a mig test, But I am clueless to how it is done with TIG. If it is ever feasible to be welded with an open root, Say something 1/4 with a 35 Deg bevel 6061

It can be done open root, easiest on the bench when you can roll the weld. It takes a lot of practice in overhead postions.hacadacalopolis wrote:Off topic;

However, I built a cold-box (several miles of 6061 T6 in several sizes) that was 10% x-ray sampling, and all the butt joints had backing rings machined to taper-fit the joint. This meant no issue with suck-back or sagging root for out-of-position welds, and frankly made 100% tie-in easier.
