The JSSC Study Group on Weld Cracking probed into the possible prevention of weld cracks that occur in welding of steel structures. In this connection, the group investigated about 100 instance of weld cracks in actual structures and studied how to select reasonable preheating conditions for the prevention of weld cracks. As a result, cold cracks had accounted for more than 90% of the weld cracks in actual steel structures. In order to quantitatively determine concrete preheating conditions to avoid cold cracking, Pw-(t_c)_<cr> criterion was extended to the practical application with consideration of practical welding procedure. It was able to develop a method wherein the optimum preheating temperature can be obtained with ease according to the actual conditions of welding.
