Abstract

The behavior of AISI 4340 steel was established after being subjected to welding process with electrode E 7018 of four millimeters in diameter, electrode E 312–16 and UTP 65 with a diameter of 3,2 mm, respectively. Samples with dimensions of 100 x 50 mm were prepared which, after the thermal welding cycle, were subjected to a non-destructive test (END) such as Barkhausen Magnetic Noise. The microstructural analysis revealed that welding AISI 4340 steel with electrodes of type E 7018 promotes the formation of the sigma phase from the ferrite and introduces a hardness of 498,70 HV causing a fragile bead, with the deposit with the UTP electrode 65 favorable changes in the Barkhausen signals, the ferrite-austenite microstructures and hardness of 315 HV are shown demonstrate the feasibility in welding with the latter.
