Tensile testing provides details on the tensile properties of a material. They can be graphically represented as a stress/ strain graph to show details such as the elastic limit, yield strength, modulus of elasticity and strain.
Purpose may include:
A bend test is a method for measuring stiffness and yield properties of certain materials. Bend tests for ductility provide way to evaluate the quality of materials by their ability to resist cracking or other surface irregularities during one continuous bend.
Bend testing determines the materials:
These characteristics can also be used to determine whether a material will fail under pressure and are important in any construction process involving ductile materials loaded with bending forces.
Charpy tests show whether a metal can be classified as being either brittle or ductile. This is particularly useful for ferritic steels that show a ductile to brittle transition with decreasing temperature.
This is used to determine:
Macro examination is used to check the quality of welds. A cross section of welded material is polished and etched for examination.
This will determine if the weld has:
This helps to examine materials for:
In the Vickers hardness testing, the test specimen is indented with a known test force (HV).
The size of indentation (the diagonals) left by the indenter is measured.
The larger the indent left by the indenter at a defined test force in the surface of a workpiece (specimen), the softer the tested material.
Microscopic Examination is conducted to study the microstructural features of the material under magnification. The properties of a material will determine how well it will perform under a given application.
These properties are dependent on the structure of the material.
Material can be examined for:
Fillet weld fracture test determines fillet weld soundness. This test is performed to reveal internal imperfections such as:
Nick Break Test is used to determine the quality of a weld and involves breaking open the weld lengthwise.
The exposed weld interior is visually inspected for any internal imperfections such as:
The test can be carried out for both Butt Welds and Fillet Welds. A groove is machined along the weld centerline to provide a convenient fracture path before the specimen is split open using a hydraulic press or a hammer.
Ferrite examination by the point count method and feritscope are performed to determine the amount of ferrite present in the weld metal, HAZ and/or base metal. The point count test is performed on a polished and etched cross-section of the specimen as per the point count method defined in ASTM E562 or a company derived specification. The point count test is applied to welds that involve the duplex stainless steels.
Ferrite examination by feritscope is a nondestructive test performed with a contact probe that calculates ferrite using electro-magnetic response.
