Description
[technical field] [0001] The invention relates to a method for predicting mechanical properties of welded joints, in particular to an interface system method for predicting mechanical properties of welded joints based on computer technology. [Background technique] [0002] Since there are many process parameters that affect the mechanical properties of welded joints, the change of each important parameter, such as preheating temperature, heat treatment temperature, and welding heat energy beyond the specified range, must be tested for welding procedure qualification; From the test to the test of the mechanical properties of the welded joints, the welding procedure evaluation involves several departments in the factory; at the same time, a lot of manpower, material and financial resources are invested to complete these tasks, which not only cost a lot of money, but also take a long time, often causing delays in production . [0003] In order to solve this problem, for a long...
