Developed by the American Association of Mechanical Engineers (ASME), the QW150 standard describes a tensile testing method. The full name of the standard is as follows: QW150 Tensile test examples, procedure and acceptance.
The ninth part of the standards published by the American Mechanical Engineers Association and updated in 2019 is the boiler and pressure vessel covers international codes. This section describes the qualification criteria for welders, solders and welding, soldering and melting operators, as well as welding, soldering and melting processes.
Accordingly, the structure of the QW150 standard is as follows:
In order to understand how the materials will react under the tensile load, tensile tests are carried out. In a simple tensile test, the material sample is drawn towards the breaking point to determine the ultimate tensile strength of the material. Material properties are usually expressed by the following two values:
Among the services provided by our organization within the framework of metallic testing services, there are also QW150 standard tests.
