Five welding processes are approved within AASHTO and the American Welding Society's bridge welding code for the fabrication of steel highway bridges. Each of these processes produce heat-affected zones (HAZs) of varying size and severity in the steel. NCHRP Research Report 1056: Toughness Requirements for Heat-Affected Zones of Welded Structural Steels for Highway Bridges, from TRB's National Cooperative Highway Research Program, presents proposed requirements for the toughness of HAZs of welded structural steels for highway bridges, and draft language for consideration by AASHTO to incorporate the research results in the next update of the bridge welding code.
