The Charpy Impact Test (or Charpy V-Notch Test) is a commonly used type of Impact Test used to determine the resistance of a material to fracture. Charpy Impact Testing uses a pendulum testing machine which strikes the Charpy specimen and measures the energy absorbed by the specimen to determine the notch hardness of the material. … Read more

A Bend Test may be carried out on a tensile testing machine with the help of certain attachments as described later in this section. A bend test is an easy and inexpensive test to apply. The method is fast and shows most weld faults quite accurately. Bend tests may be used to find a number … Read more

Tensile testing is one of the most widely used mechanical tests and is a destructive test. A tensile test helps to determine weld characteristics such as tensile strength, ductility and yield points. Tensile Test Procedure Tensile test is carried out by gripping the ends of a weld specimen in a tensile testing machine and applying … Read more

Welded joints in a structure (e.g., a bridge) are expected to possess certain service-related capabilities. Welded joints are generally required to carry loadings of various types in which the weld is subject to stress of either a simple or complex character. A finished weld is not always as good or as bad as it may … Read more
