Cold Metal Transfer ?

Well????

A lot has been tried but nothing yet as far as I have heard passes NDT, DT, Dye and X-ray. Cold transfer is used for non critical apps, but controled explosive bonding is the only process I know that is used for critical apps and is of a proprietary process and from what I have heard is very very expensive.

My guess??

From what I can compile process involves "tinning" the material with bronze. then followed with silver but i can"t seem to find anything else on it.

My guess is that the application is soley ment for decorative purposes, but would appreciate any other info

Cold transfer? Explosive?

[tacmig]

I would too..

This process is way out of my ball park and have only read about it will passing the time in the growler I'm not even going to take a shot at it. I will try to find the mag and send you the info if I can find it, I do know or perhaps better said, I think explosive bonding is a process of shape charging the Al to the steel in a controled enviroment??

The shop I used to work at (temp. layoff) had a trailer division. One of the guys I worked with showed me a piece of Aluminum somehow bonded to Steel that acted as a sort of weld in adapter. I'm not really sure how they were joined, but you could clearly see the line of speration between the two metals. I'm going to go out on a limb and say theat the strength of this join was very high as it is used on load bearing transport trailers on public roads.

Its called cladding like the nickle and copper in coins. It is done underground outside Pittsburg with explosives. The force of the blast seals the different metals together....Bob

I know what your talking about, I was also shown this on a drop deck trailer, didn't believe it until I saw it! I also was shown a coupon of 18ga cold rolled welded to a similar thickness aluminum coupon using a Fronius machine. It's cool to see constant devolopment in this great trade!

wow, thanks guy's, does anyone have any sort of references to this stuff???

I'd really appreciate it

Try this out..

I think you might get some more info from here.

A few months ago while I was healing from surgery I watched a show about this process( Explosion } welding on the discovery channel, you may be able to contact them and buy the episode and as I remember the process was very successful.

Hope this helps
