Ijika eliguqukayo lokumelana liyisici esibalulekile emishinini yokushisela i-medium frequency inverter spot. Imele ubuhlobo phakathi kwamandla okushisela kanye nokwehla kwamandla kagesi kuwo wonke ama-electrode ngesikhathi senqubo yokushisela. Ukuqonda leli jika kubalulekile ekuthuthukiseni amapharamitha wokushisela nokuqinisekisa ukushisela kwekhwalithi ephezulu. Kulesi sihloko, sizohlola umqondo wejika eliguqukayo lokumelana nokubaluleka kwawo ezinhlelweni zokushisela amabala.
- Incazelo ye-Dynamic Resistance Curve: Ijika eliguquguqukayo lokumelana libonisa ukumelana kwalapho okuhlangatshezwane nakho phakathi nenqubo yokushisela. Itholakala ngokuhlela i-welding current ngokumelene nokwehla kwe-voltage kuwo wonke ama-electrode. Leli jika lihlinzeka ngemininingwane ebalulekile ekuziphatheni kukagesi nokushisayo kwe-weldment, okuvumela ukulawula okunembayo nokuqapha inqubo yokushisela.
- Izinto Ezithinta Ijika Lokumelana Ne-Dynamic: a. Izinto Ezibalulekile: Ijika eliguqukayo lokumelana liyahlukahluka ngezinto ezihlukene ngenxa yokuhlukahluka kokuhamba kukagesi, ukuqhutshwa kwe-thermal, nezinga lokushisa elincibilikayo. Kubalulekile ukucabangela izakhiwo zezinto ezibonakalayo lapho uhumusha ijika futhi unquma imingcele ye-welding efanele. b. Ukucushwa kwe-Electrode: Umumo, usayizi, kanye nempahla yama-electrode kuthonya indawo yokuxhumana kanye nokushabalaliswa kokushisa, okubuye kuthinte ijika eliguqukayo lokumelana. Ukukhetha nokugcinwa kahle kwama-electrode kubalulekile ukuze uthole imiphumela engaguquki nethembekile yokushisela. c. Amapharamitha we-Welding: Ijika eliguqukayo lokumelana liyazwela ezinguqukweni zamapharamitha wokushisela njenge-welding current, amandla e-electrode, nesikhathi sokushisela. Ukulungisa le mingcele kungashintsha umumo nezici zejika, okuvumela ukwenziwa kahle kwenqubo yokushisela.
- Ukubaluleka Kwejika Lokumelana Kwe-Dynamic: a. Ukuqapha Inqubo: Ijika eliguqukayo lokumelana linikeza impendulo yesikhathi sangempela ngekhwalithi nokuzinza kwenqubo yokushisela. Ukuchezuka kusukela kumumo wejika okulindelekile kungabonisa izinkinga ezifana nokuthinta kabi i-electrode, ukukhiqiza ukushisa okwanele, noma ukuhlanganiswa kwezinto ezingafanele. b. Ukuthuthukiswa Kwepharamitha: Ngokuhlaziya ijika lokumelana eliguqukayo, imingcele yokushisela efanele inganqunywa ukuze kuzuzwe izici ezifiselekayo zokushisela, njengokujula kokungena, usayizi we-nugget, namandla ahlangene. Ukulungisa kahle imingcele yokushisela ngokusekelwe ekuhlaziyweni kwejika kuthuthukisa ukulawulwa kwenqubo futhi kuqinisekisa ikhwalithi yokushisela engaguquki. c. Ukutholwa Kwephutha: Izinguquko ezingazelelwe noma okudidayo kwijika eliguqukayo lokumelana kungabonisa ukuguga kwama-electrode, ukungcoliswa kwezinto, noma amanye amaphutha. Ukwengamela ijika kuvumela ukutholwa kusenesikhathi kwalezi zinkinga, okuvumela ukunakekelwa okufika ngesikhathi noma izinyathelo zokulungisa ukuze kuvinjwe izinkinga zokushisela.
- Izindlela Zokulinganisa: Kungasetshenziswa izindlela ezihlukahlukene ukuze kulinganiswe futhi kuhlaziywe ijika eliguquguqukayo lokumelana, okuhlanganisa ukuqapha ukwehla kwamandla kagesi, amasu amanje okuzwa, nezinhlelo zokutholwa kwedatha. Lawa masu athwebula ukuziphatha kukagesi osheshayo wenqubo yokushisela futhi enze kube lula ukukhiqizwa kwejika eliguqukayo lokumelana.
Ijika eliguqukayo lokumelana nemishini yokushisela i-medium frequency inverter spot iyithuluzi elibalulekile lokuqonda ukuziphatha kukagesi nokushisayo kwe-weldment. Isebenza njengomhlahlandlela wokuthuthukisa imingcele yokushisela, ukuqapha inqubo yokuzinza, kanye nokubona amaphutha angenzeka. Ngokusebenzisa ulwazi olunikezwa ijika eliguqukayo lokumelana, abakhiqizi bangafinyelela ukushisela okungaguquki kanye nekhwalithi ephezulu, bathuthukise ukukhiqiza okuphelele nokuthembeka komkhiqizo ezinhlelweni zokushisela.
