A Welding Data Dictionary

 

Abstract

This data dictionary specifies data elements that are = used to describe the design, fabrication and inspection of weldments.  It comprises welding information f= rom several authoritative sources.  Data include description of component materials, details of joints and welds, and variables of the welding processes.  The data dictionary provides, in one document, the welding informati= on needed to develop format specifications for digital data that can be exchan= ged by computer programs. 

Keywords

data dictionary, digital welding data, weld inspection results, welding procedure specification, welding terms, weldment design.

Foreword

In 1992, welding information formats were described in= two American Welding Society (AWS) specifications, AWS A9.1- Standard Guide = for Describing Arc Welds in Computerized Material Property and Nondestructive Examination Databases, and AWS A9.2 - Standard Guide for Recording A= rc Weld Material Property and Nondestructive Examination Data in Computerized Databases.  This document expands the scope of those documents and could serve as a core document if = an AWS committee undertakes a new specification project.   Current individual AWS specifications are rich in terms and data items describing materials, design and processes.  This data dict= ionary gathers the information in a single document, to be used by data modelers w= ith specific encoding formats in mind.  Examples of format specifications are STEP and XML.  The ultimate purpose is to facilit= ate exchange of welding data between application software programs developed by different vendors.
