Izimbangela zamabhamuza ku-Nut Spot Welding?

Amabhamuza angaphakathi kwamaphoyinti okushisela ekushiseleni amantongomane angaba yinkinga evamile ethinta ikhwalithi nobuqotho be-weld. Lawa mabhamuza, aziwa nangokuthi i-porosity, angenza buthaka ukushisela futhi afaka engozini ukusebenza kwawo. Kulesi sihloko, sizohlola izizathu eziyinhloko zokwakheka kwamabhamuza ekushiseleleni amantongomane futhi sixoxe ngezixazululo ezingaba khona zokunciphisa le nkinga.

1. Ukungcola:Ukuba khona kokungcola okufana nowoyela, ukugqwala, nanoma iyiphi into yangaphandle ezindaweni ezishiselwe kungaholela ekwakhekeni kwamabhamuza. Lokhu kungcola kungahwamuka ngesikhathi senqubo yokushisela, kwenze ama-voids ngaphakathi kwe-weld.
2. Ukulungiswa Kobuso Okungenele:Ukungahlanzwa okwanele noma ukulungiswa kwezindawo ezizoshiselwa kungase kubangele izinga eliphansi lokushisela. Ukuhlanza kahle kanye nokususwa kwezingqimba ze-oxide kubalulekile ekuzuzeni ama-welds aqinile futhi athembekile.
3. Igesi Elivaleleke Embobeni Enentambo:Lapho ushisela amantongomane, imbobo enentambo kwesinye isikhathi ingabamba igesi noma umoya. Le gesi ebanjiwe ikhishwa ngesikhathi sokushisela futhi ingakha amabhamuza ngaphakathi kwendawo yokushisela. Ukuqinisekisa ukuthi imbobo enentambo ihlanzekile futhi ayinazo izithiyo kubalulekile.
4. Igesi Yokuvikela Enganele:Uhlobo nezinga lokugeleza kwegesi evikelayo kudlala indima ebalulekile enqubweni yokushisela. Igesi yokuvikela enganele ingavumela amagesi asemoyeni ukuthi angene endaweni yokushisela, okuholela ekuqineni.
5. Amapharamitha we-Welding:Ukusebenzisa imingcele ye-welding engafanele, njengokushisa ngokweqile noma i-welding current ephezulu kakhulu, kungabangela ukwakheka kwamabhamuza. Lawa mapharamitha angabangela insimbi ukuthi ishise kakhulu futhi ihwamuke, okuholela ku-porosity.

Izixazululo:

1. Ukuhlanza Okuphelele:Qinisekisa ukuthi izindawo ezizoshiselwa zihlanzwa kahle futhi azinakungcola. Lokhu kungabandakanya ukusebenzisa izincibilikisi, ukuxubha izintambo, noma ezinye izindlela zokuhlanza.
2. Igesi Yokuvikela Efanelekile:Khetha igesi evikelayo efanelekile yezinto ezishiselwe futhi uqinisekise ukuthi izinga lokugeleza lilungiswa ngendlela efanele ukuze kugcinwe umoya ovikelayo.
3. Amapharamitha Welding Alungiselelwe:Lungisa imingcele yokushisela ukuze ihambisane nempahla ethile nogqinsi olushiselwayo. Lokhu kuhlanganisa i-welding current, i-voltage, nesivinini sohambo.
4. Ukukhipha Igesi:Sebenzisa izindlela zokuvumela igesi evaleleke emigodini enentambo ukubaleka ngaphambi kokushisela, njengokushisisa kuqala noma ukuhlanzwa.
5. Ukunakekela Okuvamile:Hlola futhi unakekele imishini yokushisela ukuze uqinisekise ukuthi isebenza ngendlela efanele nokuthi akukho ukuvuza noma izinkinga ezingaholela ekuqineni.

Sengiphetha, ukuba khona kwamabhamuza noma ukuqina ekushiseleleni amantongomane kungabangelwa izici ezihlukahlukene, okuhlanganisa ukungcola, ukungalungiseki kahle kwendawo, igesi evaleleke emigodini enentambo, igesi evikelayo enganele, kanye nemingcele yokushisela engafanele. Ngokubhekana nalezi zinkinga ngokuhlanzwa okufanele, igesi evikelayo efanelekile, imingcele yokushisela elungiselelwe, ukuvuthwa kwegesi, nokugcinwa okuvamile, ikhwalithi yokushisela ingathuthukiswa kakhulu, okuholela ekuxhumekeni okuqinile nokuthembeke kakhudlwana.
