Document Summary
Soldering is a process by which metals are joined together using a metal filler material melted between the work pieces. The metals to be joined are heated by a torch or soldering gun and the solder material is allowed to melt and bond the work pieces. The soldering process differs from other metal bonding techniques, such as welding, in that only the solder filler material is melted to form the bond. This process however is the exactly the same as brazing except that brazing uses a filler material with a higher melting point which requires more heat for the process. The soldering filler material is typically a soft alloy such as a tin-lead or silver alloy. These alloys are used for their distinct properties such as low melting point and high ductility. A general rule for soldering is that usually the lower the solder material melting point, the weaker the bond.
