Localized heating and repeated thermal cycling during thick-plate multi-pass welding can produce a complex residual stress state, which may impair the structural reliability of welded components used in marine engines. This study investigates a 55 mm-thick Q235 steel butt joint with a K-groove deposited in 12 passes. B...

With the trend toward higher boosting and lightweight design of diesel engines, the issue of vibration-induced failure of typical structural components has become increasingly prominent. Rapid and accurate prediction of overall engine vibration severity is key to evaluating and improving diesel engine reliability. To a...
