Soldering is a process that joins two or more types of metals through melting solder. The first soldering iron was developed in 1896 by Richard Schneider and August Tinnerhol and was called the “First Electric Heating Apparatus”.<\/p>\n

Soldering is commonly used in electronics, as it is simple and safe in joining sensitive materials. Likewise, the process is also known for metalworking, plumbing, roofing and joining wires<\/a>. Let’s take an in-depth look into soldering to find out more.<\/p>\n

\n Key Takeaways<\/span>\n
    \n
  • Soldering is a process that joins metals using a filler metal<\/strong>, typically an alloy of tin and lead, which melts at lower temperatures<\/strong> compared to the base metals.<\/li>\n
  • The three main types of soldering are soft soldering, hard soldering and brazing<\/strong>, each varying by the temperature required and the strength of the final joint.<\/li>\n
  • Soldering is widely used in electronics, plumbing, and metalworking, offering precise and reliable joints, especially for small and sensitive components<\/strong>.<\/li>\n
  • While soldering is simpler and safer than welding<\/strong>, it produces weaker joints<\/strong> and isn't suitable for high-stress and high-temperature environments.<\/li>\n <\/ul>\n <\/div>\n \n

    What Is Soldering?<\/h2>\n

    Soldering uses a filler metal with a low melting point, also known as solder, to join metal surfaces. The solder is usually made up of an alloy consisting of tin and lead whose melting point is around 235\u00b0C and 350\u00b0C, respectively.<\/p>\n

    But when tin and lead are mixed then the melting point of the mixture is reduced to 183\u00b0C. The alloy is melted by using a hot iron at above 316 \u00b0C (600 \u00b0F).<\/p>\n

    As the solder cools, it creates a strong electrical and mechanical bond between the metal surfaces. The bond allows the metal parts to achieve electrical contact while it is held in place.<\/p>\n

    Note that lead-free solders are increasingly used as an alternative to environmentally harmful lead-based solders due to regulations.<\/p>\n
