Characteristics of MIG braze welding

Abstract

Improvements in brazing technologies are not widely present as in welding technologies. Many artefacts from the encient times show that brazing technologies are in use over 5000 years, what make them older from welding procedures. A long time the brazing was applied on the king courts for making jewels and/or ornamental pieces. For a particular technologies from that time hardly to be said that they are „primitive“, because they are founded in application (as we today use to say diffusion welding/brazing procedure), which are nowdays are in use in changed form (by application of a pressure) in production of reliable components from air or cosmic industry. The application of MIG method is known and widely used in welding procedures, almost for steels (both for common structural or stainless) also in numerous nonferrous metals (aluminium, copper, titanium, etc.), but this method markably less is used for brazing. Here will be shown couple of examples of MIG brazing of some complex structural shapes.
