Welds in thin materials: Ultrasonic examination (NT NDT 013)

Abstract

  This Nordtest method specifies procedures for weld examination in thin materials by manually operated ultrasonics. The method is limited to ordinary carbon steel, aluminium alloys and austenitic steel with commonly accepted qualities for conventional ultrasonic testing. The thickness range covered is from 7 mm down to 3 mm, i.e. below the ranges covered by ordinary procedures for ultrasonic weld examination which often apply a lower limit of around 8 mm.
