[TheForge] soldering v brazing v welding (fyi)

[Justin Fellenz]

Folks,

A while back there was a discussion about the definitions of soldering
v welding v brazing, to which I added some confusion. Here's something
that just showed up on the metalshapers list.

Hi Bill & Alan:
    Just to clarify the differences of Soldering and Brazing 
http://www.jwharris.com/jwref/faq/#def gives the following definition. 
Further information is availble at the Harris site and from the
American Welding Society website.  

Definitions

What is the difference between soldering, brazing and welding?
 
Soldering - The AWS defines soldering as a group of joining processes
that produce coalescence of materials by heating them to the soldering
temperature and by using a filler metal (solder) having a liquidus not
exceeding 840ºF (450ºC), and below the solidus of the base metals.

Brazing - Brazing joins materials by heating them in the presence of a
filler metal having a liquidus above 840ºF (450ºC) but below the
solidus of the base metal.

Welding - In welding, fusion takes place with melting of both the base
metal and usually a filler metal.

    BTW,  Nice looking work Bill.  Thanks for sharing it with us.
