ASNT Ultrasonics for NDT 2017

Zetec Technology Manager for PAUT, Daniel Richard, will be delivering a training course on Wednesday June 28th at the ASNT “Ultrasonics for Nondestructive Testing” event. The course is open to all attendees and is eligible for a requalification credit.

Full Matrix Capture (FMC) is a data-acquisition process where each array element is sequentially used as a single emitter and all array elements are used as receivers creating a matrix of A-Scan data stream. Once the data of this matrix is collected, signal is processed using the Total Focusing Method (TFM) to produce an image where each pixel is a dedicated and focused focal laws in the region of interest.

This training session will explain the theory behind this technology, its strength and weakness, and explore its capability versus typical corrosion and weld examination. The agenda includes:

Introduction

• Terminology
• Standard phased array beam forming recap
• FMC data collection introduction
• TFM data processing introduction

FMC Characteristics

• Signal characteristics
• Scale factor of FMC data
• FMC versus HMC data collection
• FMC data – How to use
• FMC typical signal explained

TFM Characteristics

• Signal characteristics
• TFM Frame parameters
• Focusing capability
• Coverage capability
• Impact of frame parameters on amplitude
• Use case – Corrosion and Weld examination explained

Information of interest

• Codes situation
• Calibration situation
• Preview of the future
