Izimbangela Ze-Electrode Sticking Phenomenon ku-Medium-Frequency Inverter Spot Welding of Galvanized Steel Sheets?

Amashidi ensimbi anama-galvanized avame ukusetshenziswa ezimbonini ezihlukahlukene ngenxa yokumelana nokugqwala okuhle kakhulu. Kodwa-ke, lapho ushisela insimbi ebilisiwe kusetshenziswa umshini wokushisela indawo ye-inverter ephakathi nendawo, kungenzeka into eyaziwa ngokuthi ukunamathela kwe-electrode. Lesi sihloko sihlose ukuhlola izimbangela zokunamathela kwe-electrode ku-medium-frequency inverter spot welding of galvanized steel sheets kanye nokuhlinzeka ngemininingwane yokuthi ungayinciphisa kanjani le nkinga.

1. I-Zinc Vapor and Contamination: Enye yezimbangela eziyinhloko zokunamathela kwe-electrode ekushiseleni amashidi ensimbi ukukhishwa komhwamuko we-zinc phakathi nenqubo yokushisela. Amazinga okushisa aphezulu akhiqizwa ngesikhathi sokushisela angahwamulisa i-zinc enamathela, ebese ifinyela futhi inamathele endaweni ye-electrode. Lokhu kungcola kwe-zinc kwakha ungqimba olubangela ukuthi ama-electrode anamathele kucezu lokusebenza, okuholela ebunzimeni ekuhlukaniseni ama-electrode.
2. Ukwakheka kwe-Zinc Oxide: Uma umhwamuko we-zinc okhishwe ngesikhathi sokushisela uhlangana nomoya-mpilo wasemkhathini, wenza i-zinc oxide. Ukuba khona kwe-zinc oxide ezindaweni ze-electrode kwandisa inkinga yokunamathela. I-Zinc oxide inezinto zokunamathela, ezinomthelela ekunamatheleni phakathi kwe-electrode neshidi lensimbi elithathiwe.
3. I-Electrode Material and Coating: Ukukhethwa kwezinto ezibonakalayo ze-electrode kanye nokunamathela kungathonya futhi ukwenzeka kokunamathela kwe-electrode. Izinto ezithile ze-electrode noma okokunamathela kungase kube nokuhambisana okuphezulu kwe-zinc, okwandisa amathuba okunamathela. Isibonelo, ama-electrode anokwakheka okusekelwe ethusi ajwayele ukunamathela ngenxa yokusondelana kwawo okuphezulu ne-zinc.
4. Ukupholisa Kwe-Electrode Enganele: Ukupholisa okunganele kwe-electrode kungaba nomthelela ekunamatheleni kwe-electrode. Imisebenzi yokushisela ikhiqiza ukushisa okukhulu, futhi ngaphandle kwezindlela zokupholisa ezifanele, ama-electrode angashisa kakhulu. Izinga lokushisa eliphakeme likhuthaza ukunamathela komhwamuko we-zinc kanye ne-zinc oxide ezindaweni ze-electrode, okuholela ekunamatheleni.

Amasu Okunciphisa: Ukunciphisa noma ukuvimbela ukunamathela kwe-electrode lapho kushiselwa amashidi ensimbi anothayela ngomshini wokushisela indawo ye-inverter ephakathi nendawo, amasu ambalwa angasetshenziswa:

1. Ukugqoka kwe-Electrode: Ukugqoka njalo i-electrode kubalulekile ukususa i-zinc buildup nokugcina izindawo ezihlanzekile ze-electrode. Ukugcinwa okufanele kwe-electrode kusiza ukuvimbela ukuqoqwa komhwamuko we-zinc ne-zinc oxide, kunciphisa ukuvela kokunamathela.
2. I-Electrode Coating Selection: Ukukhetha i-electrode coatings enobudlelwane obuphansi be-zinc kungasiza ekunciphiseni ukunamathela. Izembatho ezinezakhiwo zokulwa nenduku noma izimbotshana eziklanyelwe ukushisela insimbi enamagqabhagqabha zingacatshangelwa.
3. Ukupholisa Okwanele: Ukuqinisekisa ukupholisa okwanele kwama-electrode ngesikhathi sokushisela kubalulekile. Izindlela zokupholisa ezifanele, njengokupholisa amanzi, zingasusa ukushisa ngempumelelo futhi zivimbele ukukhuphuka kwezinga lokushisa kwama-electrode ngokweqile, kunciphise amathuba okunamathela.
4. Ukuthuthukisa Amapharamitha Welding: Imingcele yokushisela yokulungisa kahle, njengamanje, isikhathi sokushisela, namandla e-electrode, angasiza ekunciphiseni ukunamathela. Ngokuthola izilungiselelo ezifanele zepharamitha, inqubo yokushisela ingathuthukiswa ukuze kuncishiswe ukuhwamuka kwe-zinc nokunamathela.

Ukwenzeka kokunamathela kwe-electrode ku-medium-frequency inverter spot welding of galvanized steel sheets ikakhulukazi kubangelwa ukukhululwa komhwamuko we-zinc, ukwakheka kwe-zinc oxide, impahla ye-electrode nezici zokumboza, kanye nokupholisa okunganele kwe-electrode. Ngokusebenzisa amasu afana nokugqoka ama-electrode avamile, ukukhetha okokugcotshwa kwama-electrode afanelekile, ukuqinisekisa ukupholisa okwanele, nokuthuthukisa imingcele yokushisela, inkinga yokunamathela ingancishiswa. Lezi zinyathelo zizofaka isandla ekusebenzeni kahle kokushisela, ukukhiqiza okuthuthukisiwe, kanye nokushisela kwekhwalithi ephezulu lapho kusebenza ngamashidi ensimbi.
