...A. De; K. Momeni; M. P. Thaddeus; L. Dorn The influence of the machine specific instantaneous current wave forms on weld nugget dimensions and weld strength is investigated over six spot welding machines. It is observed that the nature of the real-time current wave forms corresponding to a common...
