Abstract
Electrical (high silicon) steels are specifically developed steels for which the principle selection principle was based on physical properties, rather than mechanical properties. Four different MAG welded joints (S355/electrical steel with 1.78 and 2.94%Si) were tested. Best result was obtained for joint 4. Furthermore, in order to decrease difference in hardness between weld metal and base metals, a change of filler material is suggested. Also, in order to reduce overlap, a smaller diameter of wire is recommended. Finally, these joints are yet to be tested on eddy current and magnetic permeability, because they affect efficiency.
