Izimbangela zokwakheka kwe-undercut eyodwa enezinhlangothi ezimbili zeipayipi lensimbi elifakwe ngaphansi kwamanzi arc

I-Welding wire joint

Ngenxa yoshintsho kububanzi nobushelelezi bejoyinti lentambo, isivinini sokuphakela intambo sizoshintsha ngokuzumayo lapho ijoyinti yocingo idlula esondweni lokuphakela ucingo, ngaleyo ndlela kubangele ushintsho olusheshayo ku-voltage wokushisela kanye nesivinini sokuncibilika, ukunwebeka okungazelelwe kwe-weld. i-pool kanye nensimbi encibilikisiwe Ukwengeza okwanele kungabangela i-undercut eyodwa ephindwe kabili kulokhu kuhlanganiswa kwe-solder.

Ukucaciswa kokushisela

Ngaphansi kwezimo ezijwayelekile, ngeke kube nezinguquko ezinkulu ekucacisweni kwe-welding ngesikhathi sokukhiqiza okuqhubekayo.Ngakho-ke, ama-undercuts ngeke enzeka ngesikhathi sokukhiqiza okuvamile.Kodwa-ke, ngaphansi kwethonya lokunikezwa kwamandla kwangaphandle, i-welding current kanye ne-voltage kungase kuvele kungazelelwe, futhi umphumela wokushintsha okungazelelwe ekugcineni uzoholela ekuveleni kwama-undercuts.

Isifunda esifushane esisheshayo

Ngezinye izikhathi ngenxa ye-burr enqenqemeni yebhodi noma i-metal burr exutshwe ku-flux, i-circuit esheshayo izokwenzeka endaweni ethintwayo ngesikhathi senqubo evamile yokushisela.Isifunda esifushane esisheshayo sizokwenza ukuthi i-welding current kanye ne-voltage ishintshe ngokushesha, okuzogcina kuholele ekungeneni.Ukwelashwa kwe-undercut eyodwa ephindwe kabili kuyafana nendlela yokwelapha ye-undercut eyodwa, engacutshungulwa ngokugaya noma ukulungiswa.
