Welding has a severe impact on the efficiency of electrical machines. The heat added during the welding process affects the microstructure of the material and causes residual stress. This results in local degradation of the magnetic permeability and facilitates additional iron losses in the machine core. https://www.ivoryjinelle.com/amazing-offer-Ohio-University-Ohio-Bobcats-iPhone-13-Pro-Max-Impact-Case-p22134-limited-grab/
