ISO 15614-5:2017 is a technical standard that specifies the requirements for welding of metallic materials using arc welding processes. It provides guidelines for the qualification of welding procedures, as well as the acceptance criteria for welded joints.
Scope and Application
The standard applies to fusion welding of metallic materials involving arc welding processes such as gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), and submerged arc welding (SAW). It is intended for use by individuals involved in welding operations, including engineers, technicians, and quality control personnel.
Qualification of Welding Procedures
ISO 15614-5:2017 outlines the requirements for the qualification of welding procedures and defines the necessary tests and acceptance criteria. These include tests on macrosections, bend tests, tensile tests, and hardness tests. The standard also provides guidelines for documenting and recording the results of these tests.
Acceptance Criteria for Welded Joints
In addition to the qualification of welding procedures, ISO 15614-5:2017 establishes acceptance criteria for different types of welded joints. It defines the maximum allowable imperfections, such as cracks, lack of fusion, and porosity, based on the type and magnitude of the applied load. The standard helps ensure that welded joints are of sufficient quality and meet the required performance criteria.
