Abstract : Tests were made to determine if Everdur brazing is satisfactory for the welding of fillet joints in small-scale models which are subjected to explosive loading. Underwater-explosion tests were conducted on simple tray structures made of 0.03-inch black iron sheet with joints of Everdur. The Everdur fillet joints sustained a maximum strain of 10 per cent under explosive loading. Further investigation, conducted to determine the effect of the geometry of the section where a stiffening member is joined to a plate which is subjected to explosive loading, showed the geometry at the joint to be a deciding factor in the type and extent of damage to the plate; stiffeners which presented a rounded surface at the juncture with the plate provided effective protection against fracture of the plate.
