Abstract

The objective of this work was to determine the best-suited electrode to carry out therecovery of cylinder lids (cylinders heads) of the TGM8K locomotives, by applyingmanual welding for electric arc. The test specimens of nodularcast iron, obtained froma discarded head, which were welded with two types electrodes, ENi-CI (UTP8 ) andENiFe-CI ( UTP86FN ) following a technology of appropriate welding were prepared.The specimens were subject of thermic fatigue tests in an experimental installationcreated with this purpose, in which a process of heating and more severe cooling than inthe head working conditions was simulated. During the thermic fatigue tests, in thespecimens welded with electrodes ENi-CI appeared cracks at the thermic influence zoneafter 145 cycles, while in the specimens welded with electrodes ENiFe-CI, appeared atthe 585 cycles on average. Based on the study results, the authors conclude that ENiFe-CI electrodes are the best-suited for the recovery of the cylinder lids.
