The use of flaw detector after leveling the weld seam of hydraulic cylinder
After the hydraulic cylinder weld excess height is leveled, a twin crystal straight probe is used for flaw detection. The CS-3-1 comparison test block is used to make the DAC curve (motherline), and the defect equivalent is ≤φ2.


Keywords: twin crystal straight probe, DAC curve, motherline, defect equivalent.
DAC curve is not exclusive to oblique probes, and twin crystal straight probes can also be used.
Note: The flaw detector may seem simple, but in fact, the correct selection of the probe and the selection of the flaw detection test block require pre-sales judgment and accurate selection by professional technicians!
