Abstract
1,235,106. Altering physical properties; welding by fusion. INTERNATIONAL RESEARCH & DEVELOPMENT CO. Ltd. 7 Aug., 1968 [22 June, 1967], No. 28835/67. Headings B3R and B3V. A method of peening a fillet weld 3 to improve its mechanical properties comprises positioning an explosive charge 4 adjacent an exposed junction between the weld and parent metal and detonating the charge. The method increases the fatigue life of a weld and may be applied a second time before the weld is put under stress and also at intervals during the life of the weld. As shown, a pair of charges 4 is used for each weld 3, the charges being detonated simultaneously or the welds being treated separately. The charges may be supported away from the weld, Fig. 2 (not shown), and the shock waves transmitted through a solid or a liquid, e.g. under water.
