This section covers the bend testing of groove welds in butt joints and the bend testing of surfacing welds. The standard gives the requirements for bend test specimen preparation, test parameters and testing procedures but does not specify the bend radius requirements or acceptance criteria.

The base materials may be homogenous, clad or otherwise surfaced, except for hardfacing.

This standard is applicable to the following, where specified:

(1) Qualification of materials, welding personnel and welding procedures

(2) Information, specifications of acceptance, manufacturing quality control

(3) Research and development

When this standard is used, the following information shall be furnished:

(1) The specific location and orientation of the specimens

(2) The specific types of tests, for example, face bend, side bend or root bend and number of specimens required

(3) The type of data required and observations to be made

(4) Bend radius or percent (%) elongation

(5) Postweld thermal or mechanical processing treatments

Safety Precautions. Safety precautions shall conform to the latest edition of ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes, published by the American Welding Society.

Note: This standard may involve hazardous materials, operations, and equipment. The standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user to establish appropriate safety and health practices. The user should determine the applicability of any regulatory limitations prior to use.
