Setšoantšo sa Q315NS

Phello ea ts'ebetso ea ho cheselletsa mocheso ho kutu ea electrochemical ea Q315NS ho H2SO4 le tharollo ea HCl e ile ea fuputsoa. Lipotoloho tse fapaneng tsa mocheso oa weld tse nang le mocheso o phahameng o fapaneng li ile tsa sebelisoa mochining oa tlhahlobo oa Gleeble thermal-force simulation ho etsisa weld HAZ, mme ho ile ha etsoa litekanyo tsa electrochemical. Liphetho li bonts'a hore sebopeho se senyenyane sa granular bainite se entsoe ka CGHAZ ha tse ling li ne li e-na le ferrite le pearlite. Ho bola ha electrochemical ea HAZ e fapaneng e ne e fapane ho H2SO4 le HCl, ka lebaka la microstructure e fapaneng. BM le HAZs ka 50 wt. Tharollo ea % H2SO4 e na le boits'oaro bo itseng ba passivation, athe ho ne ho se na boitšoaro ba passivation ho 3.5 wt. % Tharollo ea HCl. Ho hanyetsa kutu ho HAZ ho tlase ho feta ho BM. Ho phaella moo, khanyetso ea kutu ho CGHAZ ke eona e fokolang ka ho fetisisa
