ROFL - love it - so you're saying you've been arc welding
aluminium to stainless?


You're just jealous, cos you can't do it..... )


Damn right I am.

I ain't no metallurgist or chemist, but I was told by a bloke in Nu Fab UK
to use these types of rods. They are called "Indiscriminate" with a code of
"TLD 3.4is" and are not the dis-similar ones you speak of. The don't burn
in like a normal rod, but they sort of melt and pour. All I know is they
work, and work well for what we needed.

We wanted to stop the locking nuts from being un-done on camera housings,
and when we asked around for ideas on what to use, the guys at Nu Fab UK
came up with this idea. The rods are expensive, but when we worked out how
many of the little welds we would get from one rod, the concept was just
what we needed.

The locking nut is stainless steel and the bracket is drop forged aluminium,
so it's quite tough, and the weld is done on two or three faces of the hex
where it touches the bracket. The whole thing seems to melt together quite
nicely and leaves a strong bond so the nut can't be un-screwed. They work,
and we like them.
