Abstract
A phased array system and the inspection method which is configured to inspect the weld seam of an HSAW for all standard types of flaws located both near pipe's internal and external surfaces in one scan pass, diminishing the need of making mechanical adjustment for the probes during the one pass of scan. The configuration includes the usage of at least one linear PA probe for Lamination inspection right above HAZ zone, at least one pair of PA probes for longitudinal defects inspection and holes detection and at least two pairs of PA probes for transversal defect inspections.
