Phased Array Ultrasonic Testing of Discontinuities in Iron Castings

This Industry Standard has been produced by participants in the Innovations Fund Denmark founded project WeldCast and other wind turbine manufactures and foundries in Europe.

Introduction

The scope of this specification is limited to an ultrasonic inspection using phased array on a small part of a casting product. The inspection includes re-inspection and evaluation of an already identified UT defect, conclude to be out of specification. The aim is to establish a more accurate dataset for NC decision by the OEM/design owner. The possible outcome from the OEM evaluation is expected to be one of the following:

a.         accepted as-is

b.         to be repaired by welding

c.         rejected without any repair options (component remains scrapped)

This specification is to be used in agreement between the parties (OEM, design owner, supplier). The agreement must go through non-conformity handling of any defect found out of specification with potential for a weld repair.
