  2. 21. Power electronics for resistance spot welding equipment

    Author : Jawad Saleem; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Resistance spot welding is an inexpensive and efficient way ofjoining metals. It has extensive applications in household appliancesand in automotive industries. The traditional approach in relation tospot welding machines is to use 50 Hz welding transformers. Thedrawback associated with these transformers is that they are both heavyand bulky. READ MORE
