A blind bolt using stud welding is provided to weld a bolt part and a stud part and fix the result to a parent material, thereby simplifying the structure and installation thereof. A blind bolt using stud welding includes a bolt part(10), a plurality of stud parts(20), cables(31,32), and an elastic member(33). The bolt part has a body part formed with a tapered surface(13) at a front end and a spiral surface(12) at a rear end. The stud parts contact the periphery of the tapered surface, and have slant portions at rear ends and holding grooves at front ends. The cables and the elastic member are continuously inserted into the holding grooves. The elastic member elastically supports the stud parts inward. |
