Amabala okushisela adlala indima ebalulekile ekushiseleleni indawo ye-inverter yemvamisa emaphakathi, ehlinzeka ngamajoyinti aqinile futhi anokwethenjelwa phakathi kwezindawo ezimbili zensimbi. Ukuqonda inqubo yokwakheka kwamabala e-weld kubalulekile ekuthuthukiseni imingcele yokushisela, ukuqinisekisa ukushisela kwekhwalithi, nokuzuza izakhiwo ezifiselekayo zemishini. Kulesi sihloko, sizocubungula indlela yokwakhiwa kwamabala e-weld ku-medium-frequency inverter spot welding.
- Ukuthintana Nokucindezelwa: Isinyathelo sokuqala ekwakhekeni kwendawo yokushisela ukusungulwa kokuxhumana kanye nokucindezelwa phakathi kwamathiphu e-electrode kanye nesiqeshana sokusebenza. Njengoba ama-electrode esondela endaweni yokusebenza, ingcindezi isetshenziswa ukudala ukuthintana okuqinile. Ukucindezelwa kuqinisekisa ukuthintana okusondelene futhi kuqeda noma yiziphi izikhala noma amaphakethe omoya angaphazamisa inqubo yokushisela.
- I-Resistance Heating: Uma ama-electrode esungula ukuthintana, amandla kagesi adlula endaweni yokusebenza, akhiqize ukushisisa kokumelana. Ukuminyana okuphezulu kwamanje endaweni yokuxhumana kubangela ukushisa kwendawo ngenxa yokumelana nogesi we-workpiece material. Lokhu kushisa okunamandla kuphakamisa izinga lokushisa endaweni okuthintana kuyo, okwenza insimbi ithambe futhi ekugcineni ifinyelele endaweni yayo yokuncibilika.
- Ukuncibilika Kwensimbi Nokuhlanganiswa: Njengoba izinga lokushisa likhuphuka, insimbi endaweni yokuxhumana iqala ukuncibilika. Ukushisa kudluliselwa kusuka ku-workpiece kuya kumathiphu we-electrode, okuholela ekuncibilikeni kwendawo kokubili kwe-workpiece kanye nokokusebenza kwe-electrode. Insimbi encibilikisiwe yenza ichibi endaweni yokuxhumana, idale isigaba soketshezi.
- Ukuqiniswa kanye Nokubambisana Kwezwe Eliqinile: Ngemva kokuba idamu lensimbi elincibilikisiwe selibunjiwe, liqala ukuqina. Njengoba ukushisa kuncipha, insimbi ewuketshezi iyaphola futhi iqine, ishintshe ibuyele esimweni sayo esiqinile. Phakathi nale nqubo yokuqiniswa, ukusakazeka kwe-athomu kwenzeka, okuvumela ama-athomu ocezu lokusebenza kanye nokokusebenza kwe-electrode ukuthi ahlangane futhi akhe amabhondi e-metallurgical.
- I-Weld Spot Formation: Ukuqiniswa kwensimbi encibilikisiwe kubangela ukwakheka kwendawo yokushisela eqinile. Indawo yokushisela isifunda esihlanganisiwe lapho i-workpiece kanye nezinto ze-electrode zihlangene ndawonye, zakha ilunga eliqinile neliqinile. Usayizi nokuma kwendawo yokushisela kuncike ezintweni ezahlukahlukene ezifana nemingcele yokushisela, ukwakheka kwe-electrode, kanye nezakhiwo zezinto ezibonakalayo.
- Ukupholisa Nokuqiniswa Kwangemuva Kwe-Weld: Ngemva kokwakhiwa kwendawo yokushisela, inqubo yokupholisa iyaqhubeka. Ukushisa kuyahlakazeka kusuka endaweni yokushisela kuya ezindaweni ezizungezile, futhi insimbi encibilikisiwe iqina ngokuphelele. Lesi sigaba sokupholisa nokuqiniswa sibalulekile ekuzuzeni izakhiwo zensimbi ezifiselekayo kanye nokuqinisekisa ubuqotho bejoyinti lokushisela.
Ukwakheka kwamabala e-weld ku-medium-frequency inverter spot welding kuyinqubo eyinkimbinkimbi ehlanganisa ukuthintana nokucindezelwa, ukushisisa ukumelana, ukuncibilika kwensimbi nokubopha, ukuqinisa, nokupholisa ngemva kokushisela. Ukuqonda le nqubo kusiza ukuthuthukisa amapharamitha wokushisela, ukulawula ikhwalithi yezindawo zokushisela, nokuqinisekisa amandla emishini nobuqotho bamajoyinti wokushisela. Ngokulawula ngokucophelela amapharamitha wokushisela kanye nokuqinisekisa ukuklanywa okufanele kwe-electrode nokukhetha kwempahla, abakhiqizi bangahlala bekhiqiza izindawo zokushisela ezisezingeni eliphezulu ezinhlelweni zokushisela indawo ye-inverter ye-medium-frequency.
