I-Porosity yinkinga evamile okuhlangatshezwana nayo ekushiseleleni amantongomane, okuholela ekushiseleleni okubuthakathaka nokungathembeki. Kulesi sihloko, sizohlinzeka ngombono obanzi wezixazululo ezihlukahlukene zokubhekana ne-porosity ekushiseni kwe-nut projection. Ngokusebenzisa lezi zindlela, opharetha banganciphisa ukuvela kwe-porosity futhi baqinisekise ukushisela okuqinile.
- Ukulungiswa kwendawo: Ukulungiswa kahle kwendawo kubalulekile ukuze kuncishiswe ukushisela kwamantongomane. Ngaphambi kokushisela, kubalulekile ukuhlanza ngokuphelele indawo yokukhwelana yentongomane kanye nocezu lokusebenza ukususa noma yikuphi ukungcola, okufana namafutha, ukungcola, noma ama-oxide. Lokhu kungafezwa ngokuhlanza i-solvent, ukuxubha izintambo, noma ukuqhunyiswa kwe-abrasive. Indawo ehlanzekile ikhuthaza ukungena okungcono kwe-weld futhi inciphisa ingozi yokwakheka kwe-porosity.
- Ukukhethwa kwe-Electrode: Ukukhethwa kwama-electrode wokushisela kungaba nomthelela omkhulu ekwakhekeni kwe-porosity. Kunconywa ukusebenzisa ama-electrode enziwe ngezinto ezine-conductivity ephezulu kagesi kanye nokuphindaphinda okuphansi, njengethusi noma i-alloys yethusi. Lawa ma-electrode ahlinzeka ngokudluliswa kokushisa okungcono futhi anciphise amathuba okuba igesi ibambeke, anciphise ukwakheka kwe-porosity.
- Ukuthuthukisa Amapharamitha Welding: Ukuthuthukisa imingcele yokushisela kubalulekile ukuze kuncishiswe i-porosity. Amapharamitha afana ne-welding current, isikhathi, nengcindezi kufanele ilungiswe ngokucophelela ukuze kuzuzwe ikhwalithi yokushisela efanele. Isikhathi sokushisela esinganele samanje noma isikhathi esinganele se-welding singase sibangele ukukhiqizwa kokushisa okwanele, okuholela ku-porosity. Ngakolunye uhlangothi, ukushisela okwedlulele okwamanje noma isikhathi eside sokushisela kungadala ukushisa okukhulu, kuhwamulise izinto futhi kubangele i-porosity. Ukuthola ibhalansi efanele kuyisihluthulelo sokunciphisa i-porosity.
- Ukuvikela Igesi: Kwezinye izimo, ukusetshenziswa kwamagesi okuvikela kungasiza ukunciphisa i-porosity. Amagesi avikelayo, njenge-argon noma i-helium, enza umoya ovikelayo ozungeze indawo yokushisela, ukuvimbela ukungena kwamagesi asemoyeni angafaka isandla ku-porosity. Lokhu kunenzuzo ikakhulukazi lapho kushiselwa izinto ezisebenzayo noma ezindaweni ezinamaleveli aphezulu okungcola komkhathi.
- Ukugcinwa Kwe-Electrode: Ukugcinwa njalo kwama-electrode welding kubalulekile ukuvimbela i-porosity. Ngokuhamba kwesikhathi, ama-electrode angangcoliswa noma aguge, okuholela ekudluliselweni okuncane kokushisa nokwanda kwe-porosity. Kubalulekile ukuhlanza nokuhlola ama-electrode njalo, ukususa noma yikuphi ukungcola okwakhiwe noma i-oxidation. Ukwengeza, ukushintsha ama-electrode agugile kuqinisekisa ukusebenza okungaguquki futhi kunciphisa ubungozi be-porosity.
- I-Welding Technique: Indlela efanele yokushisela idlala indima ebalulekile ekwehliseni i-porosity. Ama-opharetha kufanele aqinisekise ukuhleleka okuhle phakathi kwentongomane nesiqeshana somsebenzi, alondoloze ukucindezela okuzinzile ngesikhathi sokushisela, futhi agweme amandla amaningi e-electrode noma ukunyakaza okusheshayo. Amasu okushisela angaguquki futhi alawulwayo asiza ukunciphisa i-porosity futhi akhiqize ama-welds ekhwalithi ephezulu.
I-Porosity ekushiseleni i-nut projection ingaphazamisa ubuqotho namandla ama-welds. Kodwa-ke, ngokulandela izixazululo ezichazwe kulesi sihloko, opharetha banganciphisa ngempumelelo izinkinga ze-porosity. Ukusebenzisa ukulungiswa okufanelekile kwendawo, ukukhetha ama-electrode afanelekile, ukwenza ngcono imingcele yokushisela, ukusebenzisa isivikelo segesi, ukugcinwa kwama-electrode, nokusebenzisa amasu okushisela afanelekile kuyizinyathelo ezibalulekile zokunciphisa i-porosity kanye nokufeza ukushisela okuqinile nokuthembekile ekusetshenzisweni kokushisela amantongomane.
