1. I-Metallography
I-Metallography yenye yezona ndlela ziphambili zokwahlula imibhobho yentsimbi edibeneyo kwiimibhobho yentsimbi engenamthungo. Iipayipi zentsimbi ezidityanisiweyo ezixhathisayo kakhulu azifaki izinto zokuwelda, ngoko ke umthungo wokuwelda kumbhobho wentsimbi odityanisiweyo umxinwa kakhulu. Ukuba kusetyenziswa indlela yokusila rough uze emva koko ugqwala, umthungo wokuwelda awunakubonakala ngokucacileyo. Nje ukuba umbhobho wentsimbi odityanisiweyo oxhathisayo kakhulu udityanisiwe kwaye awukafumani unyango lobushushu, isakhiwo sokuwelda siya kwahluka kakhulu kwizinto eziphambili zombhobho wentsimbi. Ngeli xesha, indlela ye-metallographic ingasetyenziselwa ukwahlula iipayipi zentsimbi ezidityanisiweyo kwiipayipi zentsimbi ezingenamthungo. Kwinkqubo yokwahlula iipayipi ezimbini zentsimbi, kuyimfuneko ukusika isampuli encinci enobude nobubanzi obuyi-40mm kwindawo yokuwelda, ukwenza ukugawula rough, ukugawula kakuhle kunye nokupolisha, uze emva koko ujonge isakhiwo phantsi kwe-metallographic microscope. Xa kujongwa i-ferrite kunye ne-widmanstatten, izinto zomzali kunye nesakhiwo sendawo yokuwelda, umbhobho wentsimbi odityanisiweyo kunye nombhobho wentsimbi ongenamthungo unokwahlulwa ngokuchanekileyo.
2. Indlela yokugqwala
Kwinkqubo yokusebenzisa indlela yokugqwala ukwahlula imibhobho yentsimbi edityanisiweyo kunye nemibhobho yentsimbi engenamthungo, i-weld yombhobho wentsimbi edityanisiweyo elungisiweyo kufuneka ipholishwe. Emva kokuba ukupholishwa kugqityiwe, kufuneka kubonakale iimpawu zokupholishwa. Emva koko, ubuso bokugqibela bupholishwe ngephepha lesanti kwindawo yokupholishwa, kwaye ubuso bokugqibela buphathwe ngesisombululo se-nitric acid alcohol esingu-5%. Ukuba kuvela i-weld ecacileyo, kunokuqinisekiswa ukuba umbhobho wentsimbi ngumbhobho wentsimbi odityanisiweyo. Akukho mahluko ucacileyo kubuso bokugqibela bombhobho wentsimbi engenamthungo emva kokugqwala.
3. Yahlula imibhobho yentsimbi edibeneyo kunye nemibhobho yentsimbi engenamthungo ngokwenkqubo
Kwinkqubo yokwahlulahlulaimibhobho yentsimbi edityanisiweyokunye neepayipi zentsimbi ezingenamthungo ngokwenkqubo, zonke iipayipi zentsimbi ezihlanganisiweyo zidityaniswa ngokweenkqubo ezifana nokuqengqeleka okubandayo kunye nokuphuma. Ukongeza, xa iipayipi zokuwelda ze-arc eziphindaphindayo eziphezulu, eziphantsi kunye neepayipi zokuwelda ezichaseneyo zisetyenziselwa ukugquma iipayipi zentsimbi, ukugquma kwepayipi ejikelezayo kunye nokugquma kwepayipi yomthungo othe tye kuya kwenziwa, okuya kwenza iipayipi zentsimbi ezijikelezileyo, iipayipi zentsimbi ezisikwere, iipayipi zentsimbi ezi-oval, iipayipi zentsimbi ezinxantathu, iipayipi zentsimbi ezi-hexagonal, iipayipi zentsimbi eziwileyo, iipayipi zentsimbi ezi-octagonal, kunye neepayipi zentsimbi ezintsonkothileyo ngakumbi. Ngamafutshane, iinkqubo ezahlukeneyo ziya kwenza iipayipi zentsimbi ezineemilo ezahlukeneyo, ukuze iipayipi zentsimbi ezihlanganisiweyo kunye neepayipi zentsimbi ezingenamthungo zikwazi ukwahlulwa ngokucacileyo. Nangona kunjalo, kwinkqubo yokwahlula iipayipi zentsimbi ezingenamthungo ngokwenkqubo, zahlulwa kakhulu ngokweendlela zonyango lokuqengqeleka okushushu kunye nokuqengqeleka okubandayo, kwaye iipayipi zentsimbi ezingenamthungo nazo zineendlela ezimbini eziphambili, ezizezi iipayipi zentsimbi ezingenamthungo eziqengqeleka okushushu kunye neepayipi zentsimbi ezingenamthungo eziqengqeleka okubandayo. Iipayipi zentsimbi ezingenamthungo eziqengqeleka okushushu zenziwe ngokugqobhoza, ukuqengqeleka kunye nezinye iinkqubo, ingakumbi iipayipi zentsimbi ezingenamthungo ezinkulu kunye nezingqindilili zigqunywa yile nkqubo; imibhobho etsalwa ngokubandayo yenziwa ngokutsalwa kwemibhobho ngokubandayo, kwaye amandla ezinto aphantsi, kodwa ubuso bayo bangaphandle nangaphakathi buthambile.
