ABSTRACT	The LE-7 engine which will be used as the first stage main engine for the H-II rocket has been under development in Japan.This engine has many welded joints that have developed a variety of problems.Therefore,tensile properties and microstructures of Inconel-718 test specimens with welded joints were investigated at various temperatures in high
