Abstract：In view of T92 steel and Super304H steel dissimilar steel welding joint abnormalities found the hardness testing, the samples were tested by microhardness test, impact test, bending test and microstructure observation and heat treatment process analysis According to the reason that the high temperature tempering process of welding joint was not strictly enforced, the hardness of the joints of the joints with abnormal hardness was two times of heat treatment, and made the hardness value is in accordance with the design requirements.
