Izikhunta ze-Graphite zidlala indima ebalulekile ekuvukweni, ikakhulukazi kubandakanya nalezi zinto ezilandelayo:
- Ilungisiwe futhi ibekwe endaweni yokuqinisekisa ukuthi i-weldentiction igcina isikhundla esizinzile ngesikhathi senqubo yokubhidliza, ukuyivimbela ekuhambeni noma ekulimaleni, ngaleyo ndlela iqinisekise ukunemba nekhwalithi ye-welding.
Ukudluliswa kokushisa nokulawulwa kokushisa ngoba i-graphite inokuphamba okuhle okushisayo, ingakudlulisa ngokushesha ukushisa, okusiza ukulawula ukusatshalaliswa kwezinga lokushisa ngesikhathi senqubo yokubhidliza, ukuze kugcwaliswe i-weld ukuze uzuze ngokuphelele.
Ukwakha ukwakheka okuthile kanye nokwakheka kungaklanywa ngesakhiwo esithile kanye nokwakheka njengoba kudingeka ukusiza ekwakheni ukwakheka kwe-welding okuhlangene kanye ne-weldenting ehlangabezana nezidingo.
Umphumela Wokuvikela uhlinzeka ngokuvikelwa okuthile eWeldment futhi wehlise ukuphazamiseka kanye nethonya lendawo yangaphandle kwinqubo yokubhidliza, njengokuvimbela i-oxidation.
Izikhunta ze-Graphite zinezinzuzo eziningi ezibalulekile ze-Brazing:
- Ukuvuselelwa okuhle kakhulu okushisayo kungadlulisela ngokushesha ukushisa, yenza into ebhubhisayo incibilike ngokulinganayo, ithuthukise ukusebenza kahle kanye nekhwalithi yokuxhumeka okuhle okushisa okushisa okuphezulu kungahlala zizinzile endaweni ephezulu yokushisa okuvuthayo, okungekho lula ukuwonakalisa noma ukulimala.
Ukuqina okuphezulu kwamakhemikhali akulula ukuphendula ngamakhemikhali ngezinto eziphikisayo kanye ne-weldentiment, kuqinisekisa ubumsulwa kanye nokuqina kwenqubo ye-welding.
Izindleko eziphansi kakhulu ziqhathaniswa nezinye izinto zokuvimbela izinga lokushisa eliphakeme, izindleko zezikhunta zamatshe zinobuhlobo obuhle kakhulu, ezilungele ukunciphisa izindleko zokukhiqiza.
Izikhunta ze-Graphite zinethonya elibalulekile kwikhwalithi ye-Brazing:
- Okuthinta umphumela wokugcwalisa we-weld
Isikhunta esifanelekilesi esifanele singaqinisekisa ukuthi impahla ebhubhisayo igcwalisa ngokugcwele i-weld, yakha ukuhlangana okuhlanganisiwe kanye nokuhlangene okuminyene, kanye nokwenza ngcono amandla nokubekwa uphawu kokuhlanganiswa.
Nquma ukuhambelana kokuhlanganiswa
Ukusebenza kokushisa okushisayo kanye nokwakheka kwesikhunta kuzothinta ukusatshalaliswa kwamazinga okushisa kanye nezinga lokupholisa ngesikhathi senqubo yokubhidliza, ngaleyo ndlela kuthinte ukusebenza kanye nokusebenza kokuhlangana.
Okuthinta ukunemba okubucayi kwe-weldentiment
Ukunemba kwesikhunta kuhlobene ngokuqondile nokunemba kwe-weldension. Uma ukunemba okubusayo kungaphezulu, kungadala ukuphambuka kobukhulu be-weldment futhi kuthinte ukusebenza kwawo.
