The aim of the present work was to study the effect of various process parameters i.e. current, voltage, travel speed, electrode diameter, flux composition, pre heating of workpiece, electrode stick-out and edge including angle on changes in tensile strength and toughness of the weld bead geometry of HSLA Steel and to optimize the process so that minimal changes occur in the material properties...

The basic properties of the near-Earth current sheet from 8 RE to 12 RE were determined based on Time History of Events and Macroscale Interactions during Substorms (THEMIS) observations from 2007 to 2013. Ampere's law was used to estimate the current density when the locations of two spacecraft were suitable for the calculation. A total of 3838 current density observations were obtained to stu...

Force-free coils have been considered for various applications as energy storage devices. A novel energy storage system consisting of both toroidal and poloidal coils has been developed. In this system, the Lorentz forces on the two coils are in opposition and can be made to cancel by having the proper ratio of ampere-turns in the two coils. A general discussion of force-free coil design is giv...

Motor agitator alat yang digunakan untuk mengkonversi suatu energi listrik menjadi mekanik. Alat ini dapat diatur dengan kontrol sistem yaitu inverter agar mengaduk dalam keadaan rpm tinggi maupun rendah. Pada saat proses mixing bahan mengalami kenaikan ampere 5.5 Ampere. Tujuan dari penelitian adalah menganalisis kerusakan terjadi pada motor dan mengetahui diperlukan pengadukan baku kapasitas ...
