The increased awareness of environmental problems has resulted in changes to many industrial manufacturing processes. The soldering and brazing world has coped with changes to fluxes and brazing alloys by developing new materials and methods of performing soldering and brazing operations.

One of the more important indirect effects of this environmental awareness is related to the need to conserve energy. The automotive industry is Increasing its use of aluminium, not only in vehicle body construction, but in "vehicle climate" control field. and developments in other industries has dramatically increased the requirement for brazing aluminium "tube and fitting" assemblies.

Although the advances in Power electronics have made the control of electrical heat sources, such as Induction and Resistance, more sophisticated in terms of temperature profile programming and recording, these sources are not always suitable for brazing.
