Ultrasonic Testing of Welds

Updated: Feb 27, 2020

Introduction

It is not uncommon for a nondestructive testing ultrasonic technician to inspect structural welds according to the American Welding Society D1.1: Structural Welding Code – Steel (AWSD1.1), at least a few times in his or her career, and some inspectors use it daily. Completing a professional AWSD1.1 inspection, however, without the proper code specific training can be daunting. This article is designed to give the reader an introduction to the 2008 edition of Ultrasonic inspection per AWSD1.1 inspection procedure. The reader needs to be aware that some important (but routine) steps such as equipment qualifications have not been addressed here to allow the article to fit in available space. It is assumed that the reader has accomplished those tasks before proceeding on to transducer and wedge selection.
