      The A36 steel developed by ASTM international is one of the popular and widely used carbon structural steels which is mild and hot rolled. ASTM A36 has ultimate welding properties and it is perfectly suitable for punching, grinding, drilling, tapping and machining processes. Unlike higher performance alloys, these structural steel plate properties allow the steel to be used in many applications.See more on octalsteel[mask]A combined computational and experimental study on [ppe]Vibration stress relief (VSR) is an effective and economic method for reducing residual stress in various welding components. Compared with other methods, it costs much less time and energy. In this study, finite element method (FEM) was used to assist VSR treatment of large DH36 steel welded tube by determining the 1st order vibration mode of the tube and the natural frequency of the tube in
