Joint Laboratory of Brazing and Soldering of the STU MTF Institute of Materials and Institute of Production Technologies deals with the preparation of solders necessary for metallurgic joining of various metal materials. In the laboratory, via smelting highly clean metals in an electric induction or resistance furnaces in a protective atmosphere of an inertious gas (Ar or N), it is possible to prepare various soldering alloys mainly based on Sn. Further on, the development and preparation of Al-Zn based solder for soldering Mg alloys was carried out. It is also possible to execute ultrasonic soldering by UZP 2 Generator. The laboratory equipment consists of two electric induction furnaces, of which one is adjusted for smelting materials in a clean atmosphere of a protective gas. There are also two industrial electric resistance furnaces, of which one is adjusted for smelting, i.e. annealing of samples in a protective atmosphere of an innertious gas (maximum heating temperature 1200 °C). The labooratory has also a vaccum chamber with a heating graphite plate, where it is possible to monitor the diffluence and a contact angle of smelted alloys in dependance on their temperature at its disposal. There is also an installed device for high frequency induction heating which makes cladding of metal powders on steel substrate possible.
