forrasztástól

Forrasztástól is a Hungarian term that translates to "soldering" in English. It refers to a joining process used to bond two or more metal items together by melting and putting a filler metal (solder) into the joint. The filler metal, which has a lower melting point than the base metal, is heated, typically with a soldering iron, until it melts. The molten solder then flows via capillary action into the gap between the closely fitted surfaces of the parts to be joined. Once the heat is removed, the solder cools and solidifies, forming a strong electrical and mechanical bond between the parts.

Soldering is commonly used in electronics manufacturing to connect components to printed circuit boards (PCBs). It is also employed in plumbing to join copper pipes and in jewelry making. The choice of solder and soldering technique depends on the materials being joined and the specific application. Different types of solder exist, often alloys of tin and lead, although lead-free solders are increasingly used due to environmental and health concerns. The process requires careful control of temperature to ensure the solder flows properly without damaging the components being joined. Flux is often used during soldering to clean the surfaces of the metals and prevent oxidation, which can hinder the solder's ability to bond.
