No Mixing, No Welding
Posted by Geoff Weisenberger on October 1, 2007 at 9:37 AM.

I would like to augment the answer that was given to the first
question in the August Steel Quiz, which asked about the difference
between “filler metal” and “weld metal.” The term filler metal refers
to the chemistry and physical properties of the welding metal by
itself. The term weld metal refers to the chemistry and physical
properties of the weld deposit. This metal is a combination of the
effects of the welding process, the chemistry of the filler metal, and
the chemistry of the base metal. The answer, as given, did not include
the effect of the base metal. If there is no mixing of the filler metal
and base metal, the joining process is either brazing or soldering, not
welding.
