Embonini yokushisela, maningiizinhlobo zokushisela. I-arc welding kanye ne-spot welding kuphakathi kwezindlela ezivame kakhulu. Zivame ukusetshenziswa emikhakheni ehlukene futhi zidlala indima ebalulekile ezimbonini ezihlukahlukene. Njengomuntu oqalayo, kungase kube nzima ukuqonda umehluko. Uma ufuna ukufunda ngomehluko phakathi kwe-arc welding kanye ne-spot welding, isihloko esilandelayo sizokuchaza ngokuningiliziwe.

Iyini i-Arc Welding?

I-arc weldinginqubo esebenzisa ukushisa okukhiqizwa i-arc kagesi ukuze incibilike futhi ihlanganise izinsimbi ndawonye. Umthombo wamandla we-arc welding unganikeza i-direct current (DC) noma i-alternating current (AC). Ngokuya ngezidingo zokushisela, i-arc welding ingasebenzisa ama-electrode asebenzisekayo noma angasebenziseki. Ithuthukiswe ngasekupheleni kwekhulu le-19, i-arc welding ibambe iqhaza elikhulu ekwakhiweni kwemikhumbi futhi isetshenziswa kabanzi ezimbonini zezimoto nezisindayo.

Kuyini I-Spot Welding?

Spot welding kuwuhloboukumelana nokushiselaesebenzisa amandla kagesi ukukhiqiza ukushisa nokusebenzisa ingcindezi, okubangela ukuthi izindawo zokuxhumana phakathi kwezinto zokusebenza zenze i-weld nugget noma isimo sepulasitiki futhi zihlangane ndawonye. Kuyindlela yendabuko yokushisela esebenzisa ngokuyinhloko ama-electrode ethusi ukuqhuba ugesi. Amandla kagesi adlula ama-workpieces, awancibilikise ezindaweni zokuthintana, futhi lapho i-current imisa, ingcindezi iyaqhubeka nokubamba amaphuzu okuxhumana ndawonye, ​​​​yakha inhlanganisela.

Umehluko Phakathi Kwe-Arc Welding kanye Ne-Spot Welding

Isimiso Welding

I-arc welding kanye ne-spot welding isebenza ngezimiso ezahlukene. I-arc welding isebenzisa i-electrode kanye ne-workpiece ukwakha i-arc kagesi, ekhiqiza ukushisa. Izinga lokushisa eliphezulu lincibilikisa i-electrode ibe uketshezi olugcwalisa ilunga lensimbi bese lupholisa ukuze kwakhe ukushisela, okuhlanganisa izingxenye ezimbili zensimbi. Lolu uhlobo lwe-liquid-state welding.

Ngakolunye uhlangothi, i-spot welding, ihlanganisa ukupakisha ama-workpiece amabili kanye nokufaka ingcindezi ngama-electrode amabili. Amandla kagesi ashisisa amaphoyinti okuxhumana phakathi kwama-electrode nezinto zokusebenza, azenze zincibilike. Lapho ukupholisa, izingxenye zihlanganiswa ndawonye, ​​​​okukwenza kube uxhumano lwesimo esiqinile.

Imfuneko Yezinto Zokugcwalisa

Enqubweni yokushisela, i-arc welding ingasebenzisa i-filler metal noma cha. Lapho ushisela ama-workpiece amabili ndawonye, ​​impahla yokugcwalisa ingase ingadingeki. I-Spot welding ayidingi izinto zokugcwalisa; ishisa ngokuqondile ama-workpieces esimweni sepulasitiki ukuze uwahlanganise.

Ububanzi bohlelo lokusebenza

I-Spot welding kanye ne-arc welding inezinhlelo zokusebenza ezahlukene. I-arc welding ifanele ukushisela ubujamo obuyinkimbinkimbi nezinto zokusebenza ezinkulu zensimbi, okuyenza ilungele ukulungisa nokugcina izingxenye ezinkulu kanye nezicelo zemboni ezisindayo. I-Spot welding ivame ukusetshenziselwa izingxenye ezincane ezingaba amamilimitha angu-3 futhi ingcono ekushiseleni ivolumu ephezulu. Isetshenziswa kakhulu ezimbonini zezimoto nezasekhaya.

Isikhathi sokushisela

Insimbi yokushisela i-arc ithatha isikhathi eside futhi akuyona inqubo yesikhathi esisodwa. I-Spot welding iyashesha kakhulu futhi ingaqeda umkhiqizo ngomzuzu noma imizuzwana embalwa.

Izindleko zokushisela

Ukushisela i-arc kunezindleko eziphansi zokushisela, kodwa ngenxa yobunzima bayo bezobuchwepheshe, izindleko zomsebenzi zabashiseli abanekhono ziphezulu. I-Spot welding inezindleko ezingaphezulu, ngeyodwaumshini wokushisela indawokubiza imali elingana nemishini yokushisela i-arc eminingana. Kodwa-ke, izindleko zomsebenzi zabaqhubi ziphansi, ezingasindisa izindleko ngokuhamba kwesikhathi.

Imfuneko Yengcindezi Yangaphandle

Ngezidingo zengcindezi yangaphandle, i-arc welding ngokuvamile ayidingi ingcindezi yangaphandle. I-arc ekhiqizwa umthombo wamandla incibilikisa i-workpiece kanye nezinto zokugcwalisa. I-Spot welding, nokho, idinga umfutho womoya ukuze ucindezele izingxenye ezimbili zokusebenza ndawonye, ​​bese ukushisa kukhiqizwa nge-current.

Ukuphepha kokusebenza

Ukushisela i-arc kuyinselele ngokobuchwepheshe futhi kudinga abashiseli abanekhono. Uma ufuna ukusebenzisa i-arc welding, kufanele uqeqeshelwe umsebenzi. I-Spot welding ilula futhi iphephile, idinga ikhono elincane uma kuqhathaniswa. Abasebenzisi badinga kuphela ukuqeqeshwa okuyisisekelo ukuze baqalise.

Isiphetho:

Okungenhla umehluko omkhulu phakathi kwe-arc welding kanye ne-spot welding. Lapho ukhetha indlela yokushisela, kufanele ucabangele la maphuzu. Ukuthi ukhetha i-spot welding noma i-arc welding kuncike kakhulu emkhiqizweni okufanele uwushise, impahla yawo kanye nezici. Isibonelo, uma ufuna ukushisela ipayipi elikhulu lensimbi engagqwali, kungcono ukhethe ukushisela i-arc ngoba ukushisela indawo kulungele izingxenye ezincane kuphela. Ngakho-ke ngaphambi kokukhetha indlela yokushisela, qiniseka ukuthi uhlaziya isimo ngasinye ngezindlela eziningi.
