WTA informs: The art of soldering in industry and electronics

Soldering is a proven technique for joining metals securely and permanently.

· 2 min read

This process plays a crucial role in electronics, the automotive industry and many industrial applications. As your expert partner in cable assembly, we would like to explain the basics and important aspects of this technique.

What is soldering?

Soldering is a process in which two metal components are joined together using a metal alloy (solder). The solder is melted under the influence of heat without melting the base materials themselves. This results in a material-locked, non-detachable connection that is both mechanically and electrically conductive.

Soldering has a wide range of applications:

  • Electrical connections in cables, circuit boards and assemblies
  • Joining copper pipes and metal sheets in installation technology
  • Manufacturing components in the automotive and aviation industries
  • Jewellery and handicrafts for joining precious metals

Soft soldering vs. hard soldering – what is the difference?

The choice of the right soldering method depends on the area of application:

  • Soft soldering: Temperature range between 180 and 250 °C. It is preferred for electronic components, copper wires and delicate work.
  • Brazing: Temperatures from 450 °C. This process ensures particularly strong joints that can withstand higher loads, such as in sanitary, air conditioning and heating technology.

Important factors for a successful soldered joint

To ensure that a soldered joint is durable and reliable, the following aspects must be taken into account:

  • Selection of the right solder: Soft solders often contain tin and copper, while hard solders often contain silver or brass.
  • Use of a suitable flux: This removes oxide layers and improves the wetting of the solder joint.
  • Use of the appropriate soldering equipment: Soldering irons, soldering guns, soldering stations or gas soldering irons, depending on the application.

Which metals can be soldered?

Soldering is suitable for many metals and alloys, including:

  • Copper (Cu), brass (Me), bronze (Br)
  • Nickel (Ni) and nickel alloys
  • Steel, ferrous materials, stainless steel
  • Aluminium (Al) with special fluxes
  • Precious metals such as silver (Ag), which is particularly used in jewellery making
