What's the difference between a solder and a sauter?

In North America, solder is a metal alloy used to create a permanent bond between metal objects.The Latin word for "to make solid" is what the Middle English word soudur means.In order for solder to adhere to and connect the pieces together after cooling, it must be melted in order to have a lower melting point than pieces being joined.Over time, the solder should be resistant to oxidation and corrosive effects.Favorable electrical characteristics are required for solder to be used in electrical connections.

Soft solder has a melting point range of 90 to 450 C and is used in electronics, plumbing, and sheet metal work.Most of the time, ALLOYS that melt between 180 and 190 C are used.The term "hard soldering" refers to the use of alloys with a melting point above 450 C.

Some alloys can become eutectic, that is, their melting point is the same as their freezing point, and the alloy's melting Point is lower than that of either component.A paste of solid particles in a melt of the lower-melting phase can be found in non-eutectic alloys, which have markedly different solidus and liquidus temperatures.In electrical work, if the joint is disturbed in the pasty state before it has solidified completely, a poor electrical connection may result; use of eutectic solder reduces this problem.The pasty state of a non-eutectic solder can be used in plumbing to mold it during cooling.A "wiped joint" is a result of ensuring a watertight joint of pipes.

For electrical and electronics work, solder wire is available in a range of thicknesses for hand-soldering (manual soldering is performed using a soldering iron or soldering gun), and with cores containing flux.It is also available as a paste, a preformed foil shaped to match the workpiece, more suitable for mass-production, or in small "tabs" that can be wrapped around the joint and melted with a flame, for field repairs where an iron isn't usable or available.Lead and tin are still available and are great for hand-soldering.There are health and environmental benefits to avoiding lead-based electronic components.Bars of solder are used more in consumer electronics than in electrical applications.Thin solder sheets are used by jewelers to cut into snippets.

Tin and lead are commonly used to mend, coat, or join small metal objects.

In analogy to solder that joins metals, circumstances or emotions that strongly bond things together are figurative.

A low-melting alloy is one based on lead and tin or brass or silver, used for joining less fusible metals.

A metallic cement is a metal or metallic alloy that is melted.

To join by means of metallic cement, when a more metallic alloy is applied when melted.

To fry lightly and quickly, as meat, by tossing it over frequently in a hot pan with a little fat.
