| Abstract: | The performance characteristics of SA335 - P92 steel of boiler main steam pipes for uhra - supercritical generating units was presented, and its weld ability was also analyzed. To obtain welding joint which meets performance requirements for ultra supercritical generating units, welding processes adopted were introduced in detail. Practice shows that welding joint which meets performance requirements can be ensured by performing strictly the welding processes and controlling the environment of construction site. |
