AWS D14.4/D14.4M

Abstract

<strong>General</strong> <br>This specification sets forth requirements dealing with the allowable stresses, welded joint design, workmanship, procedure and performance qualification, inspection, repair and post weld treatments of welded connections used in machinery and equipment, subject to static and cyclic loading. It is intended to be used in conjunction with other specifications that provide application specific requirements (such as D14.1, D14.3, etc.). In the event a conflict arises between the application specific standard and AWS D14.4/D14.4M, the application specific standard shall take precedence. The intent of this document is to establish the effect of weld joint geometry, welding practices, and quality control on allowable stress levels. The specification also provides practices that can be used for examination of welded joints used in fabrication of machinery and equipment.
