juotetuista

Juotetuista is a Finnish term that translates to "soldered" in English. It refers to the process of joining two or more metal items together by melting and putting a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal. This process is distinct from welding, which involves melting the base metals themselves.

Soldering is commonly used in electronics to connect components to printed circuit boards and to create electrical connections in wiring. The low temperatures involved in soldering make it suitable for delicate components that might be damaged by the higher heat of welding. In plumbing, soldering is used to join copper pipes and fittings, creating watertight seals. Other applications include jewelry making, stained glass work, and the repair of metal objects.

The solder alloy is typically made of tin and lead, though lead-free solders are increasingly used due to environmental and health concerns. Other elements like silver, copper, or bismuth can be added to the alloy to modify its properties, such as increasing its strength or lowering its melting point. The success of a solder joint depends on several factors, including proper cleaning of the surfaces to be joined, the correct application of flux (a chemical cleaning agent), and the application of sufficient heat to melt the solder without overheating the components. A well-executed soldered joint should be mechanically strong and electrically conductive, depending on the application.
