Ultrasonic Testing Waveform Analysis of SA-335P92 Steel Welds in Set Box Cover

The paper undertook a detailed analysis and research for the field of ultrasonic inspection of the reflected waves in the outlet header Platen cover of the millionskilo-watt of ultra supercritical thermal power generating units. Deducing the defect shape of the cover and the principle of the defect were produced was useful for future quality control of cover producing process.
