Characteristic Evaluation of mock-up Structural Welding between casting and pipe for USC TPP
$621^{\circ}C$ 급 화력발전용 소재 실기규모 Mock-up품 구조용접부 특성평가
Abstract
In this study, actual scale welding were conducted at the USC thermal power plant turbine and main steam pipe casting candidate mock up material 9Cr-1.5Mo-CoVNbNB steel(CB2) and 9Cr-0.5Mo-MVNbN steel(P92). And to evaluate the welding process for the actual production, mechanical property testes were conducted for the weld metal. The Mock-up welding condition successfully led to an excellent structural welding joint between casting and pipe material.
