Welding Tips and Tricks

I have a job possibly coming my way to weld up pieces of 954 aluminum bronze. Does anybody have an idea of what it takes to weld this? I need to do some test pieces as samples first. Also FYI for everybody this is only decorative. It will be screwed fast to a wooden cabinet and will not hold any more than its own weight so if I can use fusion welds that would be great but if I need to buy filler I will. An alloy of filler would be good to know as well if anybody knows that

Try nickel al. bronze welding filler wire. If you try fusing the metals without using filler wire, you will probably have a cracking problem.....ron

OK thanks for that little tidbit. I am planning on tigging this is it an AC tig or a DC tig job?

Our 1 and 2 dollar coins here in AUS are made from Aluminium Bronze. Just another tidbit.

My guess would be DC, but someone else will hopefully know for sure.

If the filler is aluminum then you have to use AC like you would on all AL alloys.
It just doesnt weld right on DC.

Yes I tried (not intentionally).

You can use the DC if you move to silicon bronze which has been the one i have been using since the AL Bronze is hard to find in my neck of the woods.

I think Jody did a video not to long ago about aluminum bronze, iirc he said it is normally ran on dc but running it on ac with cleaning action turned all the way down makes it really easy to run and leaves a very good looking "weld"

I think he did that as a TIG braze on steel though @dsmabe
