Performance of the microstructure cast iron joints with different material was characterized after applying the thermal welding cycle. For the metallurgical joint in cast iron plates 10 millimeters thick and V preparation at 60 °, E 309L-16, UTP 8 and UTP 86 FN electrodes were selected. With E 309L – 16, the solidification is of a Widmanstátten or acicular austenite morphology with presence of carbides and with UTP 8 a ferritic matrix is obtained with formation carbides inside. Both are prone to cracking; for the UTP 86 FN an austenitic structure was obtained with a small amount of delta ferrite and a better solidification. |
