In this study, TIG welding process was used to prepare CLAM steel welded joints under corresponding experimental conditions
The mechanical properties of welded joints at high temperature were tested by high temperature tensile experiment
The results showed that the tensile strength, yield strength and fracture elongation of the welded joints decreased to a certain extent a
