REVIEW OF METHODOLOGIES FOR PREDICTIONS OF PREHEATING TEMPERATURE FOR MULTIPASS BUTT WELDS IN BRIDGE STEELS. FINAL REPORT

There are a variety of proposed methods for estimating preheating temperature, both experimentally and analytically. This report presents a review of the methodologies for predicting (multipass) butt weld preheating temperatures for bridge steels, as well as recommendations for their use and application.
