Ama-alloys e-aluminium yokushisela anikeza izinselele eziyingqayizivele ngenxa yezakhiwo nezici zawo ezithile.I-Medium frequency inverter spot welding iyindlela ephumelelayo yokuhlanganisa ama-alloys e-aluminium, ehlinzeka ngezinsimbi ezithembekile nezisezingeni eliphezulu.Kulesi sihloko, sizohlola ukucatshangelwa okubalulekile kanye namasu okushisela ama-alloys e-aluminium usebenzisa umshini wokushisela we-inverter ophakathi nendawo.
Ukukhethwa kwe-Aluminium Alloy:
Ama-alloys e-aluminium afika emabangeni ahlukahlukene anezakhiwo ezahlukene kanye nezakhiwo.Kubalulekile ukukhetha ingxubevange ye-aluminium efanele yohlelo oluthile kanye nezidingo zokushisela.Izinto ezinjengamandla, ukumelana nokugqwala, kanye nokushisela kufanele kubhekwe lapho kukhethwa ingxubevange.
Ukulungiswa Okufanelekile Kobuso:
Izindawo ze-aluminium kufanele zihlanzwe ngokucophelela futhi zilungiswe ngaphambi kokushiselwa.I-Aluminium oxide, eyakha ngokushesha phezulu, ingavimbela ukwakheka kokushisela okufanele.Izindlela zemishini ezifana nokuxubha izintambo noma ukuhlanzwa kwe-abrasive, kanye nokuhlanza amakhemikhali kusetshenziswa izincibilikisi noma izixazululo ze-alkaline, zivame ukusetshenziswa ukususa izingqimba ze-oxide nokuqinisekisa izindawo ezihlanzekile.
Ukusetshenziswa kwe-Protective Atmosphere:
I-Aluminium isabela kakhulu kumoya-mpilo kanye nomswakama emoyeni, okuholela ekwakhekeni kwe-oxide ngesikhathi sokushisela.Ukuvimbela i-oxidation nokugcina ikhwalithi ye-weld, kubalulekile ukudala umoya ovikelayo endaweni yokushisela.Lokhu kungafinyelelwa ngokusebenzisa amagesi okuvikela, njenge-argon noma i-helium, ngesikhathi senqubo yokushisela.
Amapharamitha wokushisela alungile:
Imingcele yokushisela, okuhlanganisa i-welding current, isikhathi, namandla e-electrode, kufanele ilungiswe ngokucophelela ukuze kufakwe ama-alloys e-aluminium.I-Aluminium ine-thermal conductivity ephakeme kakhulu uma iqhathaniswa nezinye izinsimbi, edinga ama-welding currents aphezulu ukuze kuzuzwe ukushisa nokuhlanganiswa okufanele.Ukwengeza, izikhathi zokushisela ezinde zingadingeka ukuze kunxeshezelwe izici zokushabalalisa ukushisa kwe-aluminium.
Ukukhethwa kwe-Electrode:
Ukukhetha impahla ye-electrode efanele kubalulekile ekushiseleni okuphumelelayo kwe-aluminium.Ama-alloys e-Copper avame ukusetshenziswa njengama-electrodes ngenxa ye-conductivity enhle yokushisa nokuhambisana ne-aluminium.Ukuma kwe-electrode nosayizi kufanele kucatshangelwe ukuze kuqinisekiswe ukusatshalaliswa kokushisa okufanele kanye nempilo ye-electrode.
Idizayini Ehlangene kanye Nokufaneleka:
Idizayini efanele yokuhlanganisa ibalulekile ekushiseleni ama-alloys e-aluminium.Amalunga ezinqe, amalunga ethangeni, kanye nama-T-joint yizinto ezijwayelekile zokuhlanganisa ezisetshenziswa ekushiseleni i-aluminium.Ukufakwa okuhlangene, okuhlanganisa nebanga legebe kanye nokulungiswa konqenqema, kufanele kulawulwe ngokucophelela ukuze kuqinisekiswe ukungena nokuhlanganiswa okwanele ngesikhathi senqubo yokushisela.
Ama-alloys we-aluminium wokushisela anomshini wokushisela amabala aphakathi nendawo adinga ukucatshangelwa okuqondile ukuze kuzuzwe ukushiselwa kwekhwalithi ephezulu.Ngokukhetha ingxubevange efanele ye-aluminium, ukulungisa izindawo ezingaphezulu, kusetshenziswa umoya ovikelayo, ukwenza ngcono imingcele yokushisela, nokusebenzisa ama-electrode afanelekile, abashiseli bangaqinisekisa ukushisela okuphumelelayo nokuthembekile kwe-aluminium.Idizayini ehlanganyelwe efanele kanye nokuhlanganisa kunomthelela futhi kukhwalithi yokushisela.Ngalawa masu nokucatshangelwa, ukushisela indawo ye-inverter ephakathi nendawo kubonakala kuyindlela ebalulekile yokuhlanganisa ama-alloys e-aluminium ezimbonini ezihlukahlukene, okuhlanganisa ezezimoto, i-aerospace, kanye nezicelo zasolwandle.
