I-porsity emapayiphu we-welded angenasici

I-porsity emapayipi angenasisekelo wensimbi anezinwele ezifulelweyo abhekisa kuma-voids afo amafomu alomthungo wezempi ngesikhathi senqubo ye-welding lapho igesi yehluleka ukubalekela ngesikhathi. Ukuba khona kwe-porosity kungathinta kakhulu ikhwalithi yepayipi elinenkani. Okokuqala, i-poroty inciphisa amandla nokuqina komzimba we-weld. I-porongu inciphisa indawo esebenza kahle yomthwalo we-weld, okwenza ithambeke ngokwengeziwe ekuqhekekeni lapho ibhekiswe emandleni angaphandle. Ngaphezu kwalokho, isakhiwo sensimbi esizungeze i-porolity singathola ukugxila kwengcindezi ngenxa yokuba khona kwalezi zikhala, zenze buthaka amandla nokuqina kwe-weld.

Okwesibili, i-Porolity ingathinta ukubekezela kwe-weld. Kuzinhlelo zokusebenza lapho kudingeka khona ukwenkewa okuphezulu, njengasezimbonini ze-petrochemical ne-aerospace, e-porospace embonini wezempi kungaholela ekuvuza kwabezindaba, okungaholela ekutheni kube nezingozi zokuphepha ezinzima.

Okokugcina, i-porosity ithinta ikhwalithi yobuhle ye-weld. I-surfavity engaphezulu ingenza indawo ye-weld engalingani, inomthelela omubi ukubukeka komkhiqizo nokunciphisa ukuncintisana kwayo kwemakethe.

Izimbangela ze-porosity emapayipe wensimbi engagqwali

1. Ukwelashwa okungafanele komhlaba kwezinto eziyisisekelo
   uma ingaphezulu lesisekelo liqukethe ukungcola okufana namafutha, ukugqwala, amabala amanzi, noma ukungcola kungabola futhi kukhululwe amathuba okuba ukwakheka kwe-porising eWeld.

2. Umthelela we-welding parameter
   welding yamanje, i-voltage, futhi ijubane le-welding liyizinto ezibalulekile ezithinta ukwakheka kwe-porosion. Uma ijubane le-welding lihamba kancane futhi okukhona okuphezulu kakhulu, ichibi elibunjiwe lizodlula ngokweqile, lenyuse i-solubity yamagesi. Kodwa-ke, ngesikhathi sokupholisa, igesi kungenzeka ingaphunyuke ngesikhathi, okuholela ekwakhekeni kwe-poorpu. Ngakolunye uhlangothi, uma isivinini se-welding sishesha kakhulu futhi okwamanje kuphansi kakhulu, izinga lokushisa lamachibi ancibilikisiwe lizoba liphansi kakhulu, okuphumela ekulimaleni okungekuhle kanye nobunzima ekuphumeni kobunzima begesi.

   
   

Izindlela zokuvimbela ze-porosity emapayiphu wensimbi engagqwali

Ngaphambi kokushiswa, ingaphezulu lezinto ezifuywayo kufanele lihlanzwe kahle ukuze lisuse uwoyela, ukugqwala, umswakama, isikali se-oxide, nokunye ukungcola. Ngokwengeziwe, kubalulekile ukukhetha i-welding yamanje ye-welding, i-voltage efanelekile, nejubane le-welding. Ukuqinisekisa ikhwalithi ephezulu ye-welding, kufanelekile i-welding yamanje ne-voltage kufanelekile lapho kungenzeka, ngenkathi kwehlisa ngokufanele isivinini se-welding ukuvumela isikhathi esanele segesi ukubalekela, ngempumelelo ukuvikela ukwakheka kwe-porision.
