Reliability of Aircraft Welds

This paper outlines the effects of fusion welding upon the dependability of structures in aircraft, due consideration being given to the existing conditions of welding practice found in this field. Obviously, the fusion welding of steel is of primary importance, since this is accepted practice. For the purposes of analysis, specimens prepared by experienced aircraft welders were subjected to physical tests and microscopic examination. With this information certain guiding principles in design for welding are outlined.
