Overview
A common application used in the jewelry, dental, medical and electronics industries, soldering joins two separate metal pieces by melting a metal alloy called a solder. The solder is typically available in wire form, made of various metals, with a flux core. Using a soldering iron, the solder is heated to 600 degrees fahrenheit, causing it to melt. Once it cools, a soldering joint is created that joins the two metal pieces together. The flux in the solder helps prevent oxidation during the process.
