摘要：

Acceptance criteria and non-destructive testing (NDT) procedures for weldments in liquefied natural gas (LNG) tanks in ships have been established. The significance of welding defects is analysed in the light of safety against fatigue and unstable fracture. This investigation forms a basis for the specification of ultrasonic inspection criteria, and special consideration has been given to the detection of lack of fusion. The choise of type and extent of non-destructive inspection is discussed. Experience in the use of ultrasonic testing for large LNG tanks of 9%Ni steel and aluminium-magnesium alloy 5083-0 is presented, with the advantages and disadvantages of the currently used NDT methods noted.
