This was discussed over in SED. OT? Welding, Soldering May Be Obsolete Two of the materials are a lot more expensive than tin or lead.

I've run into Indium before for soldering glass and wanted to have a go
but when I looked into it in small quantities the stuff seemed to be
about the same price as gold so was a non starter for what was
potentially a bit of fun.

There have been a lot of developments in adhesive assembly, but don't
think that welding is becoming obsolete. Laser welding is really
taking off, for example, along with friction-stir welding and all
kinds of robotic welding systems. Of our three magazines, Welding
Productivity is the one that's growing the fastest.

That's a metal I've never encountered. This process sounds like
contact cement for metal, with 1,500 psi joints. It could be an
efficient production process. Assembled cure time is a major limiting
factor for adhesive assembly for metals.

It looks to me like a metal velcro: the metal nanorods from both sides
interleave when the surfaces are pressed together, and tangle up. Except
of course real plastic velcro pieces don't melt together, and in the
Northwestern metal process some sort of intermetallic alloy develops.
