Soldering is a common way of joining metals. An inseparable connection is formed. Various equipment can be used for soldering, such as electric soldering irons. The brazing process is used for copper pipes that form gas or water installations.

The metal is held together with what is known as a solder, i.e. a binder. Soldering is slightly different from welding. The ends of the pipes are heated. The soldering iron itself is small and easy to use.

Soldering is divided into soft soldering and brazing. Precision is very important in brazing

Soft soldering

Easily fusible solder is used. The binder is an alloy of tin with cadmium or lead. Soft soldering is the most common type of soldering. Both experienced professionals and amateurs can solder. Soft solder takes various forms, i.e. a wire, a stick or a plate.


Soft and hard soldering

The high temperature of brazing is approx. 450 degrees Celsius. Industrial soldering is quite complicated. In this case, an ordinary soldering iron will not be enough. When brazing, the following are used:

  • blowtorch
  • blacksmith's fire
  • oxygen-acetylene burner
