Concept:

  • Soldering is a brazing type of operation where the filler metal has a melting temperature below 450°C.
  • In soldering, the strength of the filler metal is low.
  • Soldering is used for a neat leak‐proof joint or a low resistance electrical joint. Soldering is not suitable for high‐temperature applications.
  • During soldering the joint area should be clean and closely fitted to avoid cracks.
  • Binding wires are used to support the joints are usually made of soft iron.
  • The most commonly used material is stainless steel.
  • Another advantage to using stainless wire is that it doesn’t end up accidentally soldered to the workpiece.
