Abstract: PURPOSE: An attachment structure of a strain gauge is provided to measure a strain actuating on a point welding portion and an operating time by attaching a plurality of strain gauges around the welding portion. CONSTITUTION: An attachment structure of a strain gauge comprises a protective layer(100), an adhesive layer(200), and a strain gauge(300). The adhesive layer is attached on a bottom surface of the protective layer. The strain gauge is attached along a circular portion marked on the adhesive layer. Handle portions are formed in both sides of the protective layer. A central circle(210) is marked on the adhesive layer. An internal circle(220) and external circle(230) are successively marked in the outer side of the central circle. The strain gauges are attached in a zigzag shaped on cords of the internal and external circles.
