20.500.12556/DKUM-27037 Effect of vibration on weld metal hardness and toughness Vibration of welded parts is usually applied to achieve effects similar to thermal stress relief. With vibration, it is not only residual stresses that are affected. Using two different welding processes, the influence of vibration on hardness and toughness of the weld was measured. For each weldingprocess, two series of Charpy specimens were made over the temperature range from -60 to +20°C. The only difference between the two series was in performing welding with or without vibration. Slight differences in weld metalhardness were observed. Toughness measurements show an increase in impacttoughness and a significant increase in fracture toughness in samples which were vibrated during welding. welding welded joints residual stresses vibrational stress relief hardness toughness steel varjenje zvarni spoji zaostale napetosti vibriranje trdota žilavost jeklo true false false Angleški jezik Angleški jezik Neznano 2012-06-01 09:41:10 2012-06-01 09:41:10 2022-04-15 03:43:17 2019-07-10 12:10:53 2005 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.791.05:620.178.3 9701654 1362-1718 URN:SI:UM:DK:SOD6DQGF http://dx.doi.org/10.1179/174329305X40651 1 https://dk.um.si/Dokument.php?lang=slv&id=36273 Fakulteta za strojništvo 0 0 0
