The surface tension is one of the parameters that describes the thermodynamics of an interfacial reactions and the structure of newly created joint. The parameter of surface tension is playing an important role in many industrial, engineering processes with the contribution of fuild phase. The article is focused on the surface tension measurement methods - the laying drop, maximum gas bubble pressure and immersion. The measurement stands - computerised system for high temperature measurement of surface properties Thermo WET and integrated platform for automatic wettingforce and surface tension measurement at high temperatures - are presented. Example results of the experiments on L-Ag5P braze are shown and discussed.
