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, siqokomisa ukucatshangelwa okubalulekile kanye namasu ahilelekile.

1. Ukuqonda Amashidi Ayisithako: Amashidi angamathayela ayinsimbi ambozwe ngongqimba lwezinc ukuze awavikele ekugqwaleni. I-zinc enamathela inikeza ungqimba lomhlatshelo oluvimbela 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 nakho ukuze kutholakale 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 ngendlela efanele nokulungiswa kwendawo kubalulekile ngaphambi kokushisela amashidi anothayela. 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 akhandisiwe. 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 ukushisela kwekhwalithi ephezulu kumashidi anamathani. Lokhu kuvumela ukwakhiwa kwamaassemblies ahlala isikhathi eside futhi amelana nokugqwala, okwenza imishini yokushisela indawo ye-inverter ephakathi nendawo ibe ithuluzi elibalulekile ezimbonini ezisebenza ngensimbi.
