Abstract
The Kobe Earthquake of January 17,1995 caused an enormous amount of damage and prompted a major revision on the design, material and construction (included in manufacturing and processing). In steel structures, many damages which lead to fatal disasters occurred at the welded joints. Accordingly welding quality of welded joints directly governs capacity of steel structure. Japanese Architectural Standard Specification JASS 6 Steel Work was revised in 1996 and interpass temperature, heat input are added to main items of welding quality control. This paper describes the best control method of interpass temperature and heat input to get satisfactory welding quality based on an experiment on interpass temperature and heat input.
