In this paper, an effort is made to examine the cold metal transfer (CMT) welding of Al 5083 sheets having a thickness of 3 mm. The CMT welding was performed based on the L9 Taguchi orthogonal array with welding current (A), welding speed (mm/min) and welding frequency (Hz) as input parameters. The quality of weld was studied by measuring the reinforcement, bead width (BW), depth of penetration (DOP) and heat affected zone width (HAZW). The optimized parameters were found by the VIKOR multi-objective optimization method. The eighth experiment was identified as the optimized parameter from the VIKOR method.

The wheelchair clients are presented to numerous physical and mental medical issues related with delayed situated stance with being inert in wheelchair, e.g., weariness, torment in hip joint, pressure injuries, and so forth Other related issues are expansion in guardian reliance, lower back torments among parental figures, and injury rates during move support, and so forth Numerous old subjects who can walk are confined in wheelchairs because of the absence of standing capacity. With less parental figures and expanded quantities of lower appendage handicapped and older subjects, there is a significant need of improved wheelchair plans focused on upgraded autonomy of wheelchair clients. The focal point of present work was at planning a novel reconfigurable wheelchair joined with stand and sit abilities with the end goal of improvement of freedom and personal satisfaction of lower appendage incapacitated and old subjects. Further work presents a general item plan and improvement periods of a reconfigurable wheelchair. The significant commitments of paper can be summed up as Modeling and creation of a proposed wheelchair and testing it in an ongoing requirement with load application. The proposed creative answer for the issues of long haul wheelchair clients has a promising potential to upgrade autonomy and personal satisfaction of crippled individuals.
