| Abstract: | The paper analyzes weldability of new heat-resistant HR3C steel and its substitution welding wire--Thermanit617 （ ERNiCrCoMo-1 ）, then GTAW welding process is used to weld HR3C steel pipe joint with Thermanit617 as fillet. Inspection and analysis for mechanical properties, antiintergranular corrosion properties and structural features of test pipe joint are carded out. The test results show that it is feasible to weld HR3C steel with Thermanit617 nickel base welding wire substitution for welding material YT-HR3C. |
