Okokuqala, yenzai-electrolytic polishing.Insimbi engagqwali yokushisela yokupholisha i-electrolytic, ingathuthukisa ukumelana ne-weld surface oxidation, ngoba uma buncane ubulukhuni obungaphezulu bensimbi, kuba ngcono ukumelana nokugqwala.Futhi ukupholishwa nge-electrolytic ngemva kokushisela insimbi engagqwali kungakhiqiza ungqimba lwefilimu evikelayo eminyene, efanayo ukuze kuvikelwe insimbi yangaphakathi ukuze kuncishiswe ithuba lokugqwala kwe-oxidation.
Okwesibili, yenza ukwelashwa kwe-pickling passivation.Inhloso yokukhetha ukuhlanza kuqala ama-weld oxide ensimbi engagqwali.Inhloso ye-passivation ukukhiqiza ungqimba lwefilimu ye-oxide eminyene endaweni yensimbi, ukwandisa ikhono lokuvimbela ukugqwala kanye ne-oxidation.
