Process control plays a significant role in increasing customer demand for quality, performance, cost; safety and reliability are essential for continuous growth, securing a process that allows least distortion after the laser welding process by applying with Experimentation Design. In the current experiments, the parameters of Laser power, welding speed, and Argon shielding are being used with L4 orthogonal array. These variables were checked to find the best control level combination of output and its related least distortion and maximum tensile strength. The X-ray radiography has tested the welds’ consistency and found that they are free from the surface and internal defects. The results show that welding speed, weld processes are critical parameter, and a shielding gas are not critical.
