|This standard covers the common tests for the mechanical testing of
welds. They are defined and
illustrated in five parts related to testing of groove welds, fillet
welds, and stud welds. The
tests include: bend tests, tension tests, fracture toughness tests,
soundness tests, shear tests,
nick-break test, hardness tests, stud weld tests, and selected
This document extensively uses American Society for Testing and
Materials (ASTM) Standard Methods
and specifies how to use these methods when testing weldments. It
takes into consideration the
variations in properties that can occur between different regions
(base metal, heat-affected zone,
and weld metal) of a weldment.
Methods of hardness testing and mechanical property tests for base
metals are covered by ASTM
standards or the individual material specification. The joint tests
for brazements are covered in
ANSI/AWS C3.2, Standard Methods for Evaluating the Strength of Brazed
Joints in Shear.
This Foreword applies to all five parts. Additional information on the
mechanical testing of welded
joints may be obtained from the AWS Welding Handbook, Volume 1.
The values stated in U.S. customary units and used throughout this
document are to be regarded as
An expanded section on weldability testing is included in this edition
of B4.0. Selected
weldability test methods are described.
Safety Precautions. Safety precautions shall conform to the latest
edition of ANSI/ASC Z49.1,
Safety in Welding, Cutting, and Allied Processes published by the
American Welding Society.
