Abstract : Because of the fundamental metallurgical welding principles which are stated therein, the paper by Messrs, Bain and Llewellyn is of interest not only to the structural engineer and designer, but also to the welding engineer and metallurgist. From the welding standpoint it is believed that no criticism can be made. However, there are several statements in the paper to which attention should be directed. In discussing the effect of carbon it is stated that long experience indicates that at about 0.20% to 0.25% (with comparatively low content of other elements), a broadly applicable optimum is reached for structural carbon steels. This value of 0.25% carbon is the limit which has been set for alloy steel plate material used at the Watertown Arsenal, at Watertown, Mass., in building welded structures for gun carriages as determined experimentally from welding tests. Higher strength should be obtained by adding alloy elements rather than carbon when a weldable higher tensile steel is desired.
