Isingeniso seSpot Welding Galvanized Sheets with Medium Frequency Inverter Spot Welding Machines

I-Spot welding iyindlela esetshenziswa kabanzi yokuhlanganisa amashidi akhandisiwe ezimbonini ezihlukahlukene.Amashidi afakwe uthayela, aziwa nangokuthi insimbi eyisithako noma insimbi ehlanganiswe nezinc, anikeza ukumelana nokugqwala okuhle kakhulu nokuqina.Kulesi sihloko, sizohlola inqubo ye-spot welding amashidi amashidi usebenzisa imishini yokushisela i-medium frequency inverter spot, sigqamisa ukucatshangelwa okubalulekile kanye namasu ahilelekile.

1. Ukuqonda Amashidi Ayisithako: Amashidi angamathayela ayinsimbi ambozwe ngongqimba lwezinc ukuze awavikele ekugqwaleni.I-zinc enamathela ihlinzeka ngesendlalelo somhlatshelo esivimbela insimbi engaphansi ukuthi ingathintani ngqo nendawo ezungezile, ngaleyo ndlela inciphise ingozi yokwakheka kokugqwala.Kodwa-ke, ukuba khona kwe-zinc coating kubangela izinselele ezithile ngesikhathi sokushiselwa kwendawo, okudingeka kubhekwane nayo ukuze kuzuzwe ama-welds athembekile futhi aphezulu.
2. Ukukhethwa kwe-Electrode: Lapho ushisela amashidi akhandisiwe, ukukhethwa kwama-electrode kubalulekile.Ukucatshangelwa okukhethekile kufanele kunikezwe impahla ye-electrode kanye ne-coating ukuze kuqinisekiswe ukuhambisana ne-galvanized surface.Kunconywa ukusebenzisa ama-electrode enziwe ngezinto ezifana nama-alloys ethusi noma izinto ezinezakhiwo zokulwa nokunamathela ukuze kuncishiswe ubungozi bokunamathela kwe-zinc ezindaweni zama-electrode.
3. Ukuhlanza Nokulungiswa Kwendawo: Ukuhlanzwa okufanele nokulungiswa kwendawo kubalulekile ngaphambi kokushisela amashidi akhanithi.I-zinc enamathela emashidini ingase iqukathe ukungcola, okufana namafutha, ukungcola, noma ama-oxides, okungavimbela inqubo yokushisela futhi kubeke engcupheni ikhwalithi yokushisela.Ukuhlanza ngokuphelele usebenzisa ama-solvents afanelekile noma ama-degreasers kuyadingeka ukuze ususe noma yikuphi ukungcola futhi uqinisekise indawo ehlanzekile yokushisela.
4. Amapharamitha wokushisela: Amapharamitha we-Spot welding adlala indima ebalulekile ekuzuzeni amashidi anokwethenjelwa kumashidi anamathani.I-welding current, isikhathi sokushisela, namandla e-electrode kudingeka alungiswe ngokucophelela ukuze aphendule ukuba khona kwe-zinc coating.Ama-welding currents aphakeme kanye nezikhathi zokushisela ezinde zivame ukudingeka ukuze kuqinisekiswe ukuhlangana okufanele phakathi kwamashidi anamathani.Amandla e-electrode kufanele futhi asethwe ngendlela efanele ukuze asungule ukuthintana okwanele futhi akhuthaze ukudluliswa kokushisa okwanele ngesikhathi senqubo yokushisela.
5. Ukwelashwa Kwangemva Kokushisela: Ngemva kokushisela amashidi anezinsimbi, kubalulekile ukubhekana nezinkinga ezingaba khona ezihlobene nenqubo yokushisela.Ukukhathazeka okuvamile ukwakheka kwe-zinc spatter, okungenzeka ngenxa yokuhwamuka kwe-zinc coating ngesikhathi sokushisela.Ukunciphisa lokhu, ukwelashwa kwangemuva kokushisela okufana nokususwa kwe-zinc spatter noma ukuhlanzwa kwendawo kungase kudingeke ukuze kutholakale ukushisela okuhlanzekile nokubukeka kahle.

I-Spot welding galvanized sheets usebenzisa imishini yokushisela i-medium frequency inverter spot ihlinzeka ngendlela ethembekile nephumelelayo yokuhlanganisa lezi zinto.Ngokucabangela izici ezinjengokukhethwa kwe-electrode, ukuhlanzwa okufanele kanye nokulungiswa kwendawo, imingcele ye-welding elungiselelwe, kanye nokwelashwa kwe-post-weld, abakhiqizi bangakwazi ukufeza ukushiselwa kwekhwalithi ephezulu kumashidi anama-galvanized.Lokhu kuvumela ukwakhiwa kwamaassemblies ahlala isikhathi eside futhi amelana nokugqwala, okwenza imishini yokushisela indawo ye-inverter emaphakathi ibe yithuluzi elibalulekile ezimbonini ezisebenza ngensimbi.
