In: 10th International Conference on Precision, Meso, Micro and Nano Engineering, pp. Narayana Reddy, B., Hema, P., Eswara Reddy, C.: Role of laser beam in welding and assembly: a status review. The results indicate that the process parameters influence to obtain good mechanical properties, good surface with a remarkable decrease in fusion zone, and an acceptable weld profile with higher weld depth to width ratio. Whale optimization algorithm so as to obtain a best combination of process parameters, namely-laser power, welding speed, incident angle, focal position and focal length. The experimental investigation consists of three stages-(i) Determination of minimum number of experiments to be conducted using Taguchi’s technique, (ii) Joining of two similar metals by LBW and (iii) Estimation of the effect of each parameter with Analysis of Variance (ANOVA). Therefore, the present study concentrates on the experimental investigation of alloy AISI 4130 steel series by CO 2 Laser Beam Welding (LBW) with the objective of analyzing its effects on mechanical properties of joints. Thus, the design of the joints and their strength conditions play a greater role. Hence, metal joining by welding of similar or dissimilar metals is an important process. Laser Technology is gaining importance in manufacturing/production industries/medical field.
