This operation and the subsequent preparation of the surface shall be carried out carefully so that the hardness of the surface to be tested is not affected metallurgically.
25、The surface to be tested shall be properly prepared and preferably etched, so that accurate measurements of the diagonal of the indentations can be achieved in the different zones of the welded joint. 6 Test procedure 6.1 Rows of indentations (R) Fiures 1 to 3 give examples of hardness indentations
