About Resistance Brazing


· resistance brazing,brazing

In resistance brazing, the joint to be brazed is made part of an electric circuit in which the local heat developed by the resistance to the passage of electric current melts the brazing filler metal and joins the elements. Resistance brazing is therefore suitable for applications where rapid and localized heating is required and where electrodes can apply the pressure required to establish electrical contact. The heat is generated in the workpieces, in the electrodes or in both, depending on the dimensions and on the resistivity of the respective materials.

There are two basic resistance heating techniques:

- For brazing high conductivity work pieces, the heat, generated in low conductivity (e.g. graphite) electrodes, will be transferred by thermal conduction to the joint through the base metal.

- For low conductivity base metals, high conductivity electrodes are used and the heat is developed electrode/work piece interface.

Resistance brazing is ideal for joining small components, e.g. small temperature sensitive electronic or electro-mechanical metal components. In addition to working well with brazing alloys, this technique also works well with many lower temperature solder alloys. It can be performed in manual mode or in various degrees of automated modes, depending on configuration and production requirements.
