摘要

The objective of this study is to verify fracture toughness and strength behavior of welded joints, with and without controlled flaws. Preliminary test results (tensile, bending, metallography, microhardness and Charpy) for the steel USI-SAC- 50 are presented and discussed. Information obtained from this work will be useful for future studies of fracture mechanics and fatigue crack propagation.
