Uma kuziwa ezingxenyeni zensimbi zeshidi langokwezifiso nezivalo, ukushisela kungaxazulula inselele yomklamo.Kungakho sinikezela ngezinqubo zokushisela ezahlukahlukene njengengxenye yokukhiqiza kwethu ngokwezifiso, okuhlanganisaukushisela indawo,i-seam welding, amashisela e-fillet, ama-plug welds, nama-tack welds.Kodwa ngaphandle kokufaka izindlela zokushisela ezifanele, inqubo yokushisela i-light-gauge sheet sheet ingaba yinkinga futhi ijwayele ukwenqatshwa.Lokhu okuthunyelwe kwebhulogi kuzoxoxa ngokuthi kungani sisebenzisaI-Cold Metal Transfer (CMT) yokushiselaphezu kokushisela okujwayelekile kwe-MIG (igesi ye-inert yensimbi) noma i-TIG yokushisela (i-tungsten faka igesi).

ezinye izindlela zokushisela

Enqubweni yokushisela, ukushisa okuvela kwithoshi yokushisela kushisisa ucezu lokusebenza kanye nentambo yokuphakelayo ethoshi, kuncibilike futhi kuhlanganiswe ndawonye.Lapho ukushisa kuphezulu kakhulu, isigcwalisi singancibilika ngaphambi kokufinyelela kucezu lokusebenza futhi sibangele amaconsi ensimbi ukuthi asakazeke engxenyeni.Ngezinye izikhathi, i-weld ingashisa ngokushesha ucezu lokusebenza futhi ibangele ukuhlanekezela noma ezimweni ezimbi kakhulu, izimbobo zingashiswa engxenyeni yakho.

Izinhlobo zokushisela ezisetshenziswa kakhulu yi-MIG ne-TIG.Zombili lezi zinokukhishwa kokushisa okuphezulu kakhulu uma kuqhathaniswaI-Cold Metal Transfer (CMT) yokushisela.

Ngokuhlangenwe nakho kwethu, ukushisela kwe-TIG ne-MIG akufanelekile ukujoyina i-light-gauge sheet sheet.Ngenxa yamanani amaningi okushisa, kukhona i-warping and meltback, ikakhulukazi kunsimbi engagqwali ne-aluminium.Ngaphambi kokwethulwa kokushisela kwe-CMT, i-welding light-gauge sheet sheet ijwayele ukuba uhlobo lobuciko kunenqubo yokukhiqiza yobunjiniyela.

Isebenza Kanjani I-CMT?

I-CMT welding ine-arc ezinde ngendlela ehlukile.I-arc pulsed yenziwe yisigaba samanje esiyisisekelo esinamandla aphansi kanye nesigaba samanje sokushaya ngamandla amakhulu ngaphandle kwama-circuits amafushane.Lokhu kuholela ekutheni kungabi bikho i-spatter ekhiqizwayo.(I-Spatter amaconsi ento encibilikisiwe ekhiqizwa endaweni noma eduze kwe-arc yokushisela.).

Esigabeni samanje sokushaya, amaconsi e-welding ahlukaniswa ngendlela eqondiwe kusetshenziswa ukushaya kwenhliziyo kwamanje okufakwe umthamo onembile.Ngenxa yale nqubo, i-arc ingenisa ukushisa kuphela isikhathi esifushane kakhulu phakathi nesigaba sokushisa i-arc.

Ubude be-arc buyatholwa futhi bulungiswe ngomshini.I-arc ihlala izinzile, kungakhathaliseki ukuthi ingaphezulu le-workpiece linjani noma ukuthi umsebenzisi ushisela ngokushesha kangakanani.Lokhu kusho ukuthi i-CMT ingasetshenziswa yonke indawo nakuzo zonke izindawo.

Inqubo ye-CMT ngokomzimba ifana nokushisela kwe-MIG.Nokho, umehluko omkhulu usekuphakeleni kocingo.Kunokuba uqhubeke uye phambili ku-weld pool, nge-CMT, intambo ihoxiswa ukugeleza kwamanje.Intambo yokushisela kanye negesi evikelayo kufakwa ngethoshi lokushisela, ama-arc kagesi phakathi kwentambo yokushisela nendawo yokushisela - lokhu kubangela ukuthi ichopho lentambo yokushisela igcwale futhi ifakwe endaweni yokushisela.I-CMT isebenzisa ukwenza kusebenze okuzenzakalelayo kanye nokwenza kungasebenzi i-arc yokushisisa ukuze ishise ngendlela ehlelekile futhi ipholise intambo yokushisela kuyilapho iletha intambo ingena futhi ingahlangani ne-weld pool izikhathi eziningi ngomzuzwana.Ngoba isebenzisa isenzo sokushaya esikhundleni sokugeleza kwamandla okuqhubekayo,I-CMT yokushisela ikhiqiza ingxenye eyodwa kweshumi yokushisa eyenziwa yi-MIG.Lokhu kwehliswa kokushisa kuyinzuzo enkulu kakhulu ye-CMT futhi yingakho kubizwa ngokuthi “Okubandayo” ukudluliswa kwensimbi.

Iqiniso elisheshayo elijabulisayo: Umthuthukisi we-CMT welding empeleni uyichaza njengokuthi, "kushisa, ukubanda, ukushisa, ukubanda, amakhaza ashisayo."

Unomklamo engqondweni?Khuluma Nathi

Uma unemibuzo mayelana nokufaka i-welding ekwakhiweni kwakho,finyelelaukuze uqalise.I-Protocase ingenza izivalo zakho zangokwezifiso nezingxenye, kufikela ezinsukwini ezi-2-3, ngaphandle kwama-oda amancane.Thumela ama-prototypes akho ekhwalithi yobuchwepheshe ephuma kanye noma imiklamo enenani eliphansi futhi uqalise amaphrojekthi akho namuhla.
