Two disputes about the metallographic testing of welding joints of the high alloy steel on-site installation welding of the current power plant boiler are discussed. This thesis analyzes the reasons for the two dispute. On this basis, the accordance for the detection, detection method, qualification assessment standard and the ratio of detected parts to quantity are defined. This paper can provide reference for strengthening the quality of welding joints for high alloy steel installation welding of power station boilers.
