Course abstract

The aim of the study course is to get acquainted with the classification of technological tests of different materials, the specifics of tests of products of different assortment. Acquires methods of testing sheets, pipes, wires, rod-like materials, acquires an idea of technological tests of various types of joints, gets acquainted with methods and standards for determining the weldability, malleability, pourability, toughness, machinability of metals.
