The article summarizes the theoretical knowledge from the field of brazing of graphitic cast iron, especially by means of conventional
flame brazing using a filler metal based on CuZn (CuZn40SnSi – brass alloy). The experimental part of the thesis presents the results of
performance assessment of brazed joints on other than CuZn basis using silicone (CuSi3Mn1) or aluminium bronze (CuAl10Fe). TIG
electrical arc was used as a source of heat to melt these filler materials. The results show satisfactory brazed joints with a CuAl10Fe filler
metal, while pre-heating is not necessary, which favours this method greatly while repairing sizeable castings. The technological procedure
recommends the use of AC current with an increased frequency and a modified balance between positive and negative electric arc polarity
to focus the heat on a filler metal without melting the base material. The suitability of the joint is evaluated on the basis of visual
inspection, mechanic and metallographic testing.
