Evaluation of Energy Conversion Viability via Photovoltaic Panels Under Electric Arc Welding

Objective: This study investigates the feasibility of reusing energy generated during the welding process by exposing photovoltaic panels to electromagnetic radiation from a MIG/MAG welding arc, aiming to determine whether this radiation can produce measurable electrical power. Theoretical Framework: The research is based on concepts of photovoltaic energy conversion, electromagnetic emission from electric arcs, and energy-harvesting models that explain the interaction between welding radiation and photovoltaic materials. Method: A photovoltaic panel was positioned at different distances from a MIG/MAG welding arc. Voltage and current were recorded through a data acquisition system, allowing the calculation of generated electrical power. Results and Discussion: The panel produced electrical power when exposed to the arc, with voltage strongly influenced by distance, while current remained low. Maximum power values exceeded 0.5 W, confirming the energy conversion effect and indicating limitations related to current generation. Research Implications: Findings suggest potential use of welding processes for auxiliary clean energy harvesting. Originality/Value: The study introduces an innovative approach by integrating photovoltaic technology with industrial welding applications.
