After the Hyogo-ken Nambu Earthquake, it is of overriding importance to investigate influences of welding conditions, especially heat input and inter-pass temperature, upon the quality and the execution efficiency of welding parts in structured steel buildings . In this paper, an experiment to quantify effects of these conditions was carried out, and a relationship between heat input and inter-pass temperature was defined. As a result, it was clarified that heat input is the only index to control the quality and the execution efficiency.
