Plasma brazing of steels is performed using brazing filler metals having liquidus temperature above 1000 °C. This work shows the possibility of lowering the brazing temperature by applying brazing filler metals having a lower melting temperature. The method of high-temperature differential thermal analysis was used to establish the influence of manganese, nickel and silicon on solidus and liquidus temperatures of experimental alloys of Cu–Mn–Ni–Si system. Empirical data and mathematical processing methods were applied to determine the influence of chemical elements on calculated coefficients of the impact of alloying elements on solidus and liquidus temperatures of alloys of Cu–Mn–Ni–Si system that promotes lowering of melting temperature. The influence of nickel and silicon content at fixed quantity of manganese of 10 and 16 wt.% on the area of spreading over 08kp (rimmed) steel and melting temperature range was studied. Sound formation of brazed joints from 08kp alloy produced by plasma brazing with application of the studied alloys was proved experimentally. Ref. 16, Tabl. 2, Fig. 5
Keywords: plasma brazing, spreading area, solidus and liquidus temperature, high-temperature differential thermal analysis, melting temperature range
