FRACTURE TOUGHNESS OF BRIDGE STEELS--PHASE III REPORT: STATE OF FRACTURE TOUGHNESS TESTING OF WELDMENTS

A variety of fracture toughness tests, ranging from those designed to measure only linear elastic behavior to those that permit extensive yielding, have been developed in the past 10 years. In reviewing these test methods, it can be seen that many can be applied to weldments. However, weldment tests have special problems associated with them, and these must be identified and understood if they are to be correctly interpreted. Since the typical structural weldment contains a gamut of microstructures, the fracture toughness of weldments is really a composite of several zones of different toughness. The relative toughness of these zones depends on a number of factors such as weld metal and base plate composition, and welding process and procedure. However, in typical structural weldments, the weld and heat-affected zone are frequently as tough as, or tougher than, the base plate that is welded. /Author/
