Using the Gleeble to Study Cracking in Welds - Guest Speaker: John C. Lippold, Professor Emeritus The Ohio State University, Columbus, OH USA

Description: The “Gleeble” was originally developed to study metallurgical behavior and cracking associated with the heat-affected zone (HAZ) of welds. The hot ductility test was developed in the 1950s and is still widely used today to study liquation-related and solid-state cracking in the HAZ of structural materials. This presentation briefly reviewed the basic mechanisms that cause cracking in welds and highlighted tests developed using the Gleeble that can be used to evaluate susceptibility to these forms of cracking. Specifically, the 1) hot ductility, 2) strain-to-fracture, and 3) reheat cracking tests were described.
