Soldering is one of the most accurate methods of fusing pieces of metal together. It is used in extremely localized operations and when visual appeal is more important than strength. Bolting and riveting metal do not create a complete seal and may spoil an objectÕs appearance. Direct welding may damage the metal and alter the dimensions of the metal component by melting its edges. Soldering fuses pieces of metal by introducing a separate substance, or flux, that can be melted at a temperature lower than the host metal. The solder material may be of the same type of metal as the host metal with an alloy of a second metal such as tin to reduce the melting point. Because of its accuracy, soldering is popular among artisans in the creation of jewelry, dinnerware and small statuary. For larger works of...
