Calculate the reduction in defect rates and the associated costs of rework and scrap. Example: If defects decrease by 20%, reducing rework and scrap costs from $100,000 to $80,000, the savings are $20,000 annually.

Flexibility and Adaptability:
Evaluate the cost savings from reduced downtime and increased flexibility. Example: If reprogramming and changeover times are reduced, saving $50,000 annually in labor and lost production time, this adds to the value.

Safety and Ergonomics:
Quantify savings from reduced workplace injuries (healthcare costs, compensation claims). Example: If injury-related costs drop from $200,000 to $100,000 annually, the savings are $100,000.

Overall ROI:
Combine all savings and additional revenue and compare this to the initial and ongoing costs of the robotic welding systems. Example: Total annual benefits of $670,000 against an initial investment of $1,000,000 with annual operating costs of $100,000. ROI in the first year would be $570,000, achieving payback in less than two years.
