HOW GOOD SHOULD THE STANDARD OF HULL CONSTRUCTION BE?

The Authors discuss some systematic laboratory tests conducted by Kockums in collaboration with other large Swedish shipyards on the structural efficiency of welded ships' hulls. These tests dealt with the effects of misalignments and weld root gap on the bending and tensile fatigue strengths of cruciform test specimens. Results of fatigue strength tests, which compare butt-welded joints with full-penetration welded joints in thick plates, are discussed. No attempt is made to set out any acceptable standards for welding in ship construction. The overall test results showed that, in certain cases, a deviation from the perfect structural performance can be tolerated. The results of photoelastic model tests and the statical strength of welded joints are also dealt with. Impact tests of built-up butt welded joints are presented.
