A roll of softer filler metal used in brazing or soldering is called what?

Explanation:
The main idea is the filler metal used to join parts in soldering. A roll of softer filler metal used for soldering is solder because solder is an alloy with a low melting point that becomes liquid at relatively low temperatures and then flows into the joint to form a bond as it cools. Flux is a cleaning agent, not the filler; a brazing rod is specifically for brazing (which uses higher heat and a different filler metal), and welding wire is used for welding processes with much higher temperatures. So the term that fits a roll of softer filler metal for soldering is solder.
