Beschreibung
Zusammenfassung:	The invention provides a gas shielded welding technology of steel for a Q960 ultrahigh-strength steel structure. The gas shielded welding technology mainly comprises the steps that a certain weight proportion of welding wires made of alloying elements are adopted, and input quantities such as preheating temperature, voltage, current and welding speed which are matched with the thicknesses of different steel plates are correspondingly set. The quenching degree of a steel plate welding joint is reduced, the plastic deformation capacity of the welding joint is improved, and generation of cracks is reduced.
