ActiveWelding procedure qualification test for tubes to tube-plate joints
管与管板的焊接工艺评定试验
Application Summary AI generated
This standard specifies the test methods and acceptance criteria for qualifying welding procedures used to join tubes to tube-plates in heat exchangers, condensers, and similar pressure equipment. It is applied in the manufacturing and quality control of shell-and-tube heat exchangers, boilers, and nuclear power components where leak-tight and structurally sound tube-to-tube-plate welds are critical. The standard ensures that welding parameters produce consistent, defect-free joints under specified service conditions.
