6.11 Preheating for welding hull steels at low temperature 7. Alignment 8. Welding Joint Details 8.1 Typical butt weld plate edge preparation (manual welding and semi-automatic welding) 8.2 Typical fillet weld plate edge preparation (manual welding and semi-automatic welding) Q345 Steel Specification and Equivalent StandardQ345 steel specification:Q345 steel belongs to 16Mn steel grade, usually it is produced in hot rolled state, hot rolled steel plate, hot rolled steel coil/sheet, it has comprehensive mechanical and welding property, as it shows good performance in structural purposes, it is widely used as welding structural part in manufacturing of ship, railway and vehicles, bridges, boiler, pressure vessel container, steel oil tank, etc. Yield point of Q345 steel plate decreases as plate The importance of welding quality in ship construction - TWI1 Introduction. Welding is one of the most critical operations within ship construction. When welds fail, often the whole structure fails. [Apps et al. 2002] Over the past sixty years of developments in welding technology, the current expectation of weld quality has never been higher.
