HEAT-AFFECTED ZONE TOUGHNESS OF ELECTROSLAG WELDMENTS. FINAL REPORT

As part of a research program to improve the toughness and reliability of electroslag weldments, the Oregon Graduate Institute has developed a detailed understanding of the influence of process variables and consumables on the structure and mechanical properties of electroslag weldments. These results have been presented in a report by the Federal Highway Administration entitled "Improved Toughness and Fatigue Characteristics in Electroslag-Welded Bridge Structures" (FHWA-RD-87/026). While these initial efforts concentrated on the structure and properties of the weld metal, more recent efforts focused on the impact toughness behavior of the electroslag weld, heat-affected zone in both A527 and A588 alloys.
