Models of following testing beds have been developed and made namely the stand for research of wetting contact angle of firm surfaces by low temperature liquids drops and the stand for research of wetting contact angle of firm surfaces by metals melts. Special quartz-metal hermetical cartridges in which it is possible to heat samples up to 1100 C in vacuum have been developed and made. The technique, device for the research of wetting contact angle of solid inorganic surface by the melted metal under imitation action of acceleration great values using by centrifugal forces has been developed and made and wetting contact angle of a quartz glass by melted gold at increased compared with terrestrial conditions gravitation action namely 5 - 15 g nave been investigated. Two techniques for research of wetting contact angle of solid surfaces by low-temperature and high-temperature liquids and technique of definition of gravitation influence on fused solder keeping in wide and high brazing gap have been developed.
