7.5 mm thick ultrafine grained Q345 steel strip was welded by CO2 gas metal arc welding using solid wire and flux cored wire under heat inputs of 4, 6 and 10 kJ/cm. Effect of welding wire and heat A solid state bonding technology for metal plate by shear Nov 01, 2020 · Two key process parameters, deformation ratio and deformation rate, are analyzed by experiments using Q345 steel from the perspective of microstructure and bonding strength. The main findings are:(i) With increasing deformation ratio, the width of bonding interface gradually decreased and the refined grains on both sides of the bonding interface are found.

Fabrication, microstructures and mechanical properties of

Jun 01, 2018 · The elastic modulus, ultimate strength (UTS) and 0.2% yield strength (YS) of 1.2% ZrO2 particle dispersion-strengthened Q345 steel reached 184 GPa, 441 MPa and 680 MPa, respectively. Conversely, the ductility of as-cast samples decreased with increasing ZrO2 content. 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

welding(Metal Active-Gas welding) is widely used in the Q345 steel welding field, When the shielding gas mainly consists of Ar and a small amount of active gases such as CO. 2, O. 2, CO. 2 +O. 2, etc, this welding procedure is called metal active-gas welding, namely MAG welding [1-3] . MAG welding has the characteristics of the argon
