DESTRUCTIVE TESTING (ED)
It is a destructive test; the testing piece/sample is destroyed in order to obtain the necessary results. After destructive testing, the sample is no longer applicable for further use.
are many types of tests to evaluate the behaviour of an impact weld bead, the most relevant being the Charpy.
One of the most used tests. It helps reveal properties in the material, such as resistance to deformation, stress-strain curve, tensile strenght, fracture deformation, Young’s modulus and ductility measures.
By metallography, the welding microstructure is studied, that is to say, the different phases of the metallic alloys are defined.
It is the resistance capacity of metals to be penetrated. In welding, it is measured in the heat affected zone (HAZ).
