Abstract
Laser Technology is gaining importance in manufacturing/production industries/medical field. Hence, metal joining by welding of similar or dissimilar metals is an important process. Thus, the design of the joints and their strength conditions play a greater role. Therefore, the present study concentrates on the experimental investigation of alloy AISI 4130 steel series by CO2 Laser Beam Welding (LBW) with the objective of analyzing its effects on mechanical properties of joints. 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). 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 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.
