As I understand it, welding is using extreme heat to bind two metals together and soldering uses a third metal to bind them together.

--quote--
Welding: fastening two pieces of metal together by softening with heat and applying pressure
--endquote--

--quote--
Soldering: Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal
--endquote--

I knew the difference in process, but still searched for a good definition and the below is from wisegeek.com

"Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal into the joint."

"Welding is the process of joining metals by melting the parts and then using a filler to form a joint."

In other words So during welding, the metals are joined by melting part of them with filler metal/alloy.

In soldering, only the filler metal/alloy is melted make a joint. So usually soldering occurs at a lower temperature than welding.
