Corrosion Fatigue Crack Growth Rates of Weldments in Q1N Steel,
Abstract
Low frequency fatigue crack growth rates in air and seawater are reported for manual metal arc, synergic metal inert gas, electron beam and laser beam welds in Q1N steel. The stress corrosion crack growth susceptibility in seawater of the weldments was also studied and both the electron beam and laser beam welds exhibited susceptibility whilst the other welds and parent steel did not. All welds except the 'as-welded' laser beam welds showed silmilar fatigue crack growth rates to the parent plate. When tested in seawater the laser beam weld was found to exhibit exceptionally fast crack growth rates. The factors influencing fatigue crack growth in weldments are discussed. (Author)
