Extraction of samples from steel elements and tensile test

Extraction of samples of metal carpentry from elements such as pillars, beams, rods, plates or functional or decorative elements in exercise to determine the steel mechanical characteristics (yield stress, tensile strength, and strain under maximum force). The sampling involves the selection of the metal portion to be removed, which must preferably have a planar or rectilinear conformation (flat, round or tube) and a total length of approximately 300-450 mm (the length and the shape of the specimen to be obtained depends on its width). The sample is extracted by cutting with an angle grinder, and the steel element is then restored by welding a steel sheet of equal dimensions to the piece taken. After localizing and cataloguing the specimen with adequate photographic documentation, a tensile test at a state-authorized laboratory is finally carried out.
