Resistance welding machine magnetic field calculation

Ovaj završni rad fokusira se na probleme zračenja elektromagnetskog polja koji utječu na čovjeka koji upravlja strojem za zavarivanje. Proučeno je električno i magnetsko polje te su definirane njegovi utjecaji na čovjeka. Napravljene su simulacije u Quickfieldu da bi se dobile vrijednosti gustoće magnetskog toka i gustoće struje. Dobivene vrijednosti su uspoređene s propisanim normama te je utvrđeno da ih značajno prelaze. Na kraju je opisano istraživanje u kojem je uz pomoć kompenzacijskih zavojnica uspješno reducirano magnetsko polje kojem je izložen radnik.This paper focuses on electromagnetic field radiation problems affecting the man operating the welding machine. The electric and magnetic fields and its effects were studied and also their effect on humans were defined. Simulations were made in Quickfield to obtain values of magnetic flux density and current density. The obtained values were compared with those defined by standards and were found to significantly exceed them. Finally, a study is described in which, with the help of compensating coils, the magnetic field in the workers space is successfully reduced
