Abstract

Resistance spot welding (RSW) is commonly used in manufacturing and automotive industry; because of their advantages such as high speed and high production, suitability for automation, easy to process and low cost. Generally, the “trial and error” method based on the knowledge and experience of the welder has been widely adopted by the industry for the selection the optimum parameters in order to achieve a good quality of welds. This project deals with the investigation of microstructure and mechanical properties of weld joint of AHSS and SPCC. The main objectives of this project to find the optimum parameters of resistance spot welding process for three layers. For the design of the experiment, the Full Factorial Design was employed by using Design-Expert software, and total eight runs of experiment selected three factors such as weld time, weld current, and electrode force was conducted. The studies of mechanical properties are consisting by using two tests; tensile test, and microstructure and also analyze mechanical properties and quality of resistance spot weld for three layers. Analysis of Variance (ANOVA) technique was used to check the adequacy of the model developed and F-test has been used for determining the most significant parameters affecting the output response. As a conclusion, the result shows that the weld current plays an important role in determining the maximum tensile strength and nugget size.
