This document summarizes a study on parameters that affect welding current in resistance seam welding processes. The study was conducted at a company that manufactures storage tanks using seam welding. The objective was to reduce welding current and thereby reduce power consumption. Various parameters that influence welding current were investigated, including contact area between electrodes and workpiece, cooling of welding wheels, electrode force, electrode coating material, and electrical contacts in the welding machine. Adjusting these parameters, such as increasing contact area, improving cooling, calibrating electrode force, using electrode coatings, and ensuring good electrical contacts, helped reduce welding current and lower power consumption for the company.
