2.3 Ultrasonic flaw detection
The forging of the mould will be ultrasonically tested as per JB/T1581-1996, and the grade of the detection is in the following:
A: Without bursts, crack, shrinking hole and other defects.
B: The defect with size within OD2mm can be ignored.
C: Individual defect with diameter of φ 2~φ 4mm is permitted, and the distance of the neighboring
Defects should be more than the 10 times of the bigger one's. For 100cm2's area, the quantities of
The defects with diameter of φ 2~φ 4mm should not exceed 3.
D: There should not have compact district.
