700 Celsius? that's hot, possibly a typo??
700F is 370C,
Be that as it may, a rose by any other name is still a rose.
[Soft] soldering with metals like Sn Pb runs out around 300-350C, then you
can have [hard] soldering if you prefer with other metals up to 700, and
different metals again and call it brazing from there on.
I thought welding was when you don't have any metals.

Mike

The American Welding Society www.aws.org has established the magic
temperature of 700 ° C as the separation point. Below 700 ° C is soldering,
700 and above is brazing/welding.
It's pretty hard to imagine a soldering tool/tip combination nearing 700 °
C. But I'll admit that I've used tungston tip resistive soldering tweezers
with just a bit too much abandon and I've made solderable connector cups
glow bright red. Well, I guess I kinda just wanted to see how hot the
tweezers could get it. It's an easy way to turn a good connector into scrap.

Interesting post Mike,
At the risk of going a little off topic I've never quite understood the
distinction between a solder and a braze. Is there a clear cut difference in
the metallurgy of the different joints?
Regards,
