Mohd Nur Syaffiq Mahmood Strength investigation on resistance spot welding of low carbon steel and stainless steel / Mohd Nur Syaffiq Mahmood Kuantan, Pahang : UMP, 2013 xvi, 69 p. : ill. (some col.) ; 30 cm. + 1 CD-ROM Project paper ( Bachelor of Mechanical Engineering) -- Universiti Malaysia Pahang - 2013 Bibilography : p. 60-64 Resistance spot welding (RSW) had been widely used in automotive industry; because of their advantages easily to process and low cost, high speed and high production, suitability for automation. About 2000-7000 spot welds were used in joining modern vehicles. This project deals with the investigation of failure mode and mechanical properties of weld joint of low galvanized steel and stainless Steel. The main objective of this project is strength investigation using RSW of low carbon steel and stainless steel. For design of experiment, Taguchi method was employed by using Minitab software, and total nine sets experiment with 3 type of parameter (current, squeeze time, pressure) were conducted. The studies of mechanical properties, are consists of various tests; Tensile test, Coach Peel test, Hardness test, microstructure to analyze and investigate the weldability of galvanized Steel and stainless Steel sheet. Visual inspection was done to determine the failure mode of the spot welding. As a result, tensile test have larger strength variation than the coach-peel test. Wider width and depth of weld nugget affect the weldability of the welding. Different parameters were obtained for optimum parameter for tensile test and coach peel test by using Taguchi method. Almost pullout failure mode occurs where failure at heat affected zone (HAZ) around the nugget circumference.
