Hello people!

We have just has some air conditioning installed at work.
When they wanted to join two pipes together, they used a tool to
stretch one of the pipes so the other pipe then fitted inside it,
then they brazed it.

Can this sort of thing be done for normal copper water pipes for
soldering?

Am I correct in thinking this just spreads the very end of the
pipe, rather than stretching 2cms or so for another pipe to fit
inside?
If so, where can I get the appropriate tool, or what is it called
so I can try to find one if they exist!

Sparks...

If you haven't access to a lathe, bung a bit of iron railing or mild
steel rod into the chuck of an electric drill and use a file to
reduce about 15mm at the end to be just over the diameter of the
pipe and dome the end. Bang that into the end of the copper pipe.
Voila!

Makes a nice neat looking join

For the benefit of the tape, Raden is stumped.

Even i can decipher what MrP is proposing.

For the benefit of those who had too much pop last night

Take a suitable piece of material to make the tool from. Turn it down
to just over the diameter of the pipes to be joined (a method for those
with no access to alathe is given), for about 15mm along it length.
Round off the end a little. Take one of the pipes to be joined and use
the tool just fabricated by whacking it into the end of the pipe with a
hammer thus stretching the diameter of the pipe so that it will fit
over the other piece to be joined.

Quite simple really.
