Abstract : The mechanical and metallurgical characteristics of the types of higher strength weldable steels being introduced to industry are discussed, emphasising advantages and shortcomings for use in welded structures. It is suggested that if the utmost use is to be made of these steels, the basic approach to the design of a welded structure should be examined critically and, where advantageous, design methods based only on stress theory should be replaced by those which consider all possible modes of failure for the structure and set safe working loads to prevent such failures. Some of the outstanding problems that the use of these steels have for the designer, the steelmaker, the fabricator and the metallurgist are outlined to indicate areas where further research and developmental work should be rewarding.
