Emishinini yokushisela indawo ye-inverter ye-medium-frequency, isikhala phakathi kwama-weld nuggets sidlala indima ebalulekile ekunqumeni ikhwalithi namandla ejoyinti le-weld. Ukulawula okufanele kwesikhala se-weld nugget kubalulekile ukuqinisekisa ukushisela okungaguquki nokuthembekile. Kulesi sihloko, sizohlola ukubaluleka kwesikhala se-weld nugget kanye nezidingo zokuthola imiphumela emihle ezinhlelweni zokushisela indawo ye-inverter ye-medium-frequency.
- Isikhala se-Weld Nugget Nokubaluleka Kwaso: Isikhala se-weld nugget sibhekisela ebangeni eliphakathi kwama-weld nuggets aseduze endaweni yokushisela. Ithinta ngokuqondile umthamo wokuthwala umthwalo, ubuqotho besakhiwo, nokusebenza okuphelele kwejoyinti le-weld. Isikhala se-weld nugget esinganele singaholela ekushiseleni okubuthakathaka noma okungathembeki, kuyilapho ukuhlukana okukhulu kungase kuphazamise amandla ahlangene kanye nokuqina. Ngakho-ke, ukugcina isikhala se-weld nugget esifanelekile kubalulekile ekuzuzeni ikhwalithi yokushisela oyifunayo.
- Izinto Ezithonya Isikhala Se-Weld Nugget: Izinto ezimbalwa zithonya isikhala se-weld nugget emishinini yokushisela indawo ye-inverter ephakathi nendawo:
- Ubukhulu Bezinto: Izinto ezizacile ngokuvamile zidinga isikhala se-nugget esiseduze, kuyilapho izinto eziwugqinsi zingavumela isikhala esithe ukuvuleka.
- I-Welding Yamanje: I-welding current ithonya usayizi nokusabalalisa ukushisa kwe-weld nugget. Ukulungiswa kahle kwe-welding current kusiza ukulawula isikhala se-weld nugget.
- Ukucushwa kwe-Electrode: Ukuma nokwakheka kwama-electrode kungaba nomthelela ekwakhekeni nosayizi we-weld nugget, ngaleyo ndlela kuthinte isikhala phakathi kokushisela.
- Izimfuneko Zesikhala Se-Weld Nugget: Nakuba izimfuneko ezithile zezikhala ze-weld nugget zingahluka kuye ngesicelo namazinga womkhakha, kunemihlahlandlela ejwayelekile okufanele icatshangelwe:
- Isikhala Esanele: Ama-weld nuggets kufanele ahlukaniswe ngokwanele ukuze kuqinisekiswe ukuthi ama-nuggets angawodwana angasekela umthwalo osetshenzisiwe futhi asabalalise ukucindezeleka ngokulinganayo.
- Isikhala Esifanayo: Ukungaguquguquki kusikhala se-weld nugget eduze kwelunga kubalulekile ekugcineni amandla alinganayo kanye nobuqotho besakhiwo.
- Izinguquko Ezincishisiwe: Isikhala se-weld nugget kufanele silawulwe ngaphakathi kokubekezelelana okwamukelekayo ukuze kugwenywe ukuhlukahluka okungase kuholele ezindaweni ezibuthakathaka noma ukungezwani ekuhlanganyeleni kwe-weld.
- I-Weld Nugget Overlap: Kwezinye izinhlelo zokusebenza, ukugqagqana okuncane kwama-weld nuggets kungase kufiseke ukuze kuqinisekiswe ukuhlangana okuqhubekayo namandla ahlanganisiwe athuthukisiwe.
Emishinini yokushisela indawo ye-inverter yemvamisa emaphakathi, isikhala se-weld nugget sithinta ngqo ikhwalithi nokusebenza kwejoyinti le-weld. Ukugcina isikhala esifanele kuqinisekisa umthamo owanele wokuthwala umthwalo, ubuqotho besakhiwo, namandla okushisela jikelele. Izinto ezinjengokuqina kwempahla, i-welding current, kanye nokumiswa kwe-electrode kunomthelela esikhaleni se-weld nugget. Ngokuhambisana nezidingo zesikhala esanele, esifanayo, nesilawulwayo, ama-opharetha angakwazi ukuzuza ukushisela kwekhwalithi ephezulu ngamandla aphelele nokuthembeka ezinhlelweni zokushisela indawo ye-inverter ye-medium-frequency.
