Modified-SST for Uniaxial Characterization of Electrical Steel Sheets Under Controlled Induced Voltage and Constant Stress

The influence of Tungsten Insert Gas (TIG) and Plasma welding on the microstructure, mechanical and magnetic properties of non-oriented electrical steels is presented and evaluated. Samples of sizes of 5.5 cm x 5.5cm x 2.0 mm were prepared from stock plate, installed on the welding table and welded at welding speeds and pulsed currents following a predesigned protocol. The samples microstructure was studied using SEM after standard mechanical grinding and polishing procedures. The characterization of the samples is concluded with microhardness tests and magnetic measurement (Barkhausen Noise) on TIG and Plasma welded joints in order to investigate the influence of welding on the magnetizing behavior of a high Si-alloyed grade of non-oriented electrical steel.

Electrical Steel Sheets

The anisotropy of magnetic properties in non-oriented electrical steel sheets can be evaluated by measuring Epstein specimens in the radial directions. The magnetic properties measured on ring cores are practically equal to the approximate values of magnetic properties determined by Epstein specimens in the radial directions. Non-oriented electrical steel sheets with anisotropy are not desirable for motors but are suitable for transformers and fluorescent lamp ballasts. The core loss and magnetic induction as measured with ring specimens are better with non-oriented electrical steel sheets with anisotropy than with non-oriented electrical steel sheets with random crystallographic orientation. This phenomenon depends on the texture change of the product.
