Ukushisela kuwumsebenzi obalulekile lapho kwakhiwe izinto eziningi ezenziwe ngensimbi ne-aluminium.Ukuqina kwesakhiwo sonke kanye nempumelelo yephrojekthi kuvame ukuncika kwikhwalithi ye-weld.Ngakho-ke, ngaphandle kwemishini yekhwalithi efanele, udinga futhi ukwazi ukuthi izakhi zomuntu ngamunye kufanele zixhunywe kanjani.Enye yezinto eziguquguqukayo kuyo yonke inqubo yindlela yokushisela.Ngezinhloso zalokhu okuthunyelwe, sizogxila kuphela ku-arc welding ngama-electrode ahlanganisiwe.
Kuyini ukushisela kwe-arc manual?
Yonke inqubo ilula kakhulu.Ingenye yezindlela ezidume kakhulu zokushisela.Iqukethe ukuncibilika kwekhava kanye ne-electrode esetshenziswayo ngezinto ezishiselwe ngokusebenzisa i-arc kagesi.Iningi lemisebenzi yenziwa ngesandla futhi izinga lomsebenzi lincike ekhonweni lomshiseli.Kodwa-ke, kunezici okufanele uzicabangele uma ufuna ukusebenza ngobungcweti.Kufanele uhlole, phakathi kokunye:
umthombo wamanje oqondile noshintshayo, okungukuthi umshini wokushisela odumile
ikhebula elinesibambi se-electrode
intambo yaphansi ene-electrode clamp
uhlobo lwesigqoko sokuzivikela kanye nezinye izesekeli
Ngaphandle kwenqubo yokushisela ngokwayo, ukukhethwa kobubanzi be-electrode yesici esishiselwe kubaluleke kakhulu.Ngaphandle kwayo, ukwenza i-weld enhle akunakwenzeka.Yini okudingeka uyinake ukuze ujabulele umphumela wokugcina?
Ukukhetha ububanzi be-electrode ye-workpiece - udinga ukwazi!
Ukukhethwa kwe-diameter ye-electrode yesici esishiselwe ngendlela ye-MMA kuncike kubukhulu be-weld noma impahla eshiselwayo.Isikhundla oshisela kuso sibalulekile.Ngokuvamile, kungacatshangwa ukuthi ububanzi busukela ku-1.6mm kuya ngisho ku-6.0 mm.Kubalulekile ukuthi ububanzi be-electrode bungadluli ubukhulu bento ohlose ukuyishisela.Kufanele kube kuncane.Ezincwadini ze-welding uzothola ulwazi lokuthi ububanzi be-electrode kufanele bube bukhulu ngangokunokwenzeka.Lesi sinyathelo singonga kakhulu.Ngakho-ke, izinto ezinobukhulu obungu-1.5 mm kuya ku-2.5 mm ziboshwe kangcono nge-electrode ene-cross section ye-1.6 mm.Kuthiwani kwezinye izimo?
Izibonelo zobukhulu bezinto ezibonakalayo kanye nobubanzi obufanele be-electrode.
Ukuze uthole umbono ongcono wokukhethwa kwe-diameter ye-electrode ye-workpiece, ngezansi uzothola uhlu olufushane lobukhulu bezinto ezithandwa kakhulu kanye nobubanzi obufanele be-electrode.
Ubukhulu bezinto - ububanzi be-Electrode
1.5mm ukuze 2.5mm - 1.6mm
3.0mm ukuze 5.5mm - 2.5mm
4.0mm ukuze 6.5mm - 3.2mm
6.0mm ukuze 9.0mm - 4.0mm
7.5mm ukuze 10mm - 5.0mm
9.0mm ukuze 12mm - 6.0mm
