What does tinning mean?
Tinning means applying a thin coating of tin to another metal, either to protect the underlying surface from corrosion or to make it easier to solder. The word may name the process itself, the resulting coating, or the action of carrying out the work as the gerund of the verb 'tin'. Tinning was historically important in the manufacture of cookware, vessels, and other iron or steel products, because the tin layer helped keep moisture away from vulnerable metal beneath it. It also remains important in electrical and electronics work, where wires, terminals, and printed circuit boards are coated so that solder will adhere readily. In modern usage, the term has a mainly technical character and is less common in everyday speech than the more general word 'coating'. It is most often encountered in metal finishing, sheet-metal work, soldering, and the preparation of electrical connections.
The coating of a metal surface with tin, or the process of applying such a coating.
"The tinning of the containers was completed before they were shipped."
Normally used in technical or industrial contexts; it may name either the process or the resulting coating.
To coat a metal surface with tin.
"The technician is tinning the wire before soldering it."
In this use, 'tinning' is the -ing form of the transitive verb 'tin'.
Tinning is normally a mass noun naming a process or coating. The plural 'tinnings' is not standard.
"The tinning of the metal was completed before assembly."
Before stainless steel, a thin layer of tin helped protect iron cookware from rust.

Where does tinning come from?
Tinning was formed in English by adding the suffix '-ing' to 'tin', following the ordinary English pattern for process nouns and gerunds. English 'tin' continues Old English 'tinn' and belongs to Germanic; it is related to German 'Zinn', Dutch 'tin', and Swedish 'tenn', although its ultimate origin remains uncertain. The '-ing' formation is especially productive in English for naming industrial and manufacturing processes.
