1.5 mm thick SUS304 austenitic steel sheet was used as the test material to study the spot weld bonding process and fatigue performance. The joint performance was analyzed by the process, strength distribution, fatigue life and F-N curve. The effectiveness of experimental data was analyzed by t distribution, pivot method and Weibull distribution. Results show that under the same parameters, the nugget diameter of the spot weld bonding joint is larger than the resistance spot welding joint. The static strength of the spot weld bonding joint is decreased by 25% compared with the spot weld, and it is increased by 33% compared with the adhesive joint. At the same loading level, the fatigue life of the spot weld bonding joint is increased by 60%-100% compared with the spot weld.
