Given the test program of thermal fatigue resistance overlay welding materials for repairing the casting pipe model by analyzing the material, serving condition, failure modes and failure mechanism of casting pipe model. Using the self-constraint thermal fatigue test method to study the effect of overlay welding material of heat-resistant steel with different alloy scope on the thermal fatigue properties, so that make a foundation for the research of grain refinement on surfacing materials used in casting pipe model. Studies have shown that low-alloy heat-resistant steel surfacing materials are suitable for repairing the casting pipe model.
