Ukushisela izinti ze-aluminium usebenzisa imishini yokushisela izinqe kungaba inselele ngenxa yezakhiwo eziyingqayizivele ze-aluminium.Lesi sihloko sihlola amasu asebenzayo okugwema izinkinga zokushisela futhi siqinisekise ukukhiqizwa kwamashisela ekhwalithi ephezulu lapho kusetshenziswa imishini yokushisela izinqe ze-aluminium.
1. Inhlanzeko Ibalulekile:
- Ukubaluleka:Izindawo ze-aluminium ezihlanzwe kahle zibalulekile kuma-welds angenasici.
- Umkhuba Wokuvimbela:Hlanza kahle iziphetho zezinti ze-aluminium ngaphambi kokushisela ukuze ususe noma yiziphi izendlalelo ze-oxide, ukungcola, noma ukungcola.Sebenzisa indlela yokuhlanza efanele, njengokuxubha ucingo noma ukuhlanza amakhemikhali, ukuze uqinisekise indawo ehlanzekile.
2. Umkhathi olawulwayo:
- Ukubaluleka:I-Aluminium isebenzisana kakhulu nomoya-mpilo futhi ingakha izendlalelo ze-oxide ngesikhathi sokushisela.
- Umkhuba Wokuvimbela:Yenza ukushisela endaweni elawulwayo, njengegumbi legesi elivikelayo, ukuvimbela ukuchayeka kumoya-mpilo.Lokhu kunciphisa ukwakheka kwe-oxide phakathi nenqubo yokushisela.
3. Ukulinganisa Okufanelekile Nokuqondanisa:
- Ukubaluleka:Ukulinganisa okunembile nokuqondanisa kubalulekile ekushiseleleni okuphumelelayo kwenduku ye-aluminium.
- Umkhuba Wokuvimbela:Qinisekisa ukuthi iziphetho zenduku ziqondaniswe kahle futhi zihlanganiswe ngokuqinile.Ukungaqondani kahle noma izikhala kungaholela ekulimaleni kokushisela.
4. Amapharamitha wokushisela alungile:
- Ukubaluleka:Imingcele ye-welding engalungile ingaholela kukhwalithi ye-weld engalungile kanye namaphutha.
- Umkhuba Wokuvimbela:Setha imingcele yokushisela, njengamanje, i-voltage, nengcindezi, ngaphakathi kwebanga elinconyiwe lokushisela induku ye-aluminium.Landela imihlahlandlela yomkhiqizi womshini ukuze uthole izilungiselelo ezifanele.
5. Ukugcinwa kwe-Electrode:
- Ukubaluleka:Ama-electrode adlala indima ebalulekile enqubweni yokushisela.
- Umkhuba Wokuvimbela:Hlola njalo futhi ugcine ama-electrode welding.Qinisekisa ukuthi zihlanzekile, azinawo umonakalo, futhi ziqondaniswe kahle.Ama-electrode angcolile noma awonakele angaholela ekulimaleni kokushisela.
6. Ukuhlolwa Kwangaphambi Kokushisela:
- Ukubaluleka:Ukuqhuba ama-weld wokuhlola kusiza ukukhomba izinkinga ezingaba khona ngaphambi kokushisela ukukhiqiza.
- Umkhuba Wokuvimbela:Yenza izivivinyo zangaphambi kokushisela kumasampula wezintambo ukuze uhlole ikhwalithi yokushisela futhi ulungise amapharamitha uma kudingeka.Lokhu kuvumela ama-opharetha ukuthi acule kahle izilungiselelo futhi avimbele amaphutha ekushiseleni kokukhiqiza.
7. Ukuhlola Ngemva Kokushisela:
- Ukubaluleka:Ukuhlola okubonakalayo kubalulekile ukuze kutholwe izinkinga zokushisela.
- Umkhuba Wokuvimbela:Hlola indawo eshiselwe ngokubona noma yiziphi izimpawu zokukhubazeka, njengokuqhekeka, i-voids, noma ukuhlangana okungaphelele.Sebenzisa izindlela zokuhlola okungabhubhisi (i-NDT) njengokuhlola ukungena kwedayi noma ukuhlolwa kwe-ultrasonic ukuze uhlole ngokucophelela.
8. Ukupholisa Okufanelekile:
- Ukubaluleka:Ukupholisa okusheshayo kungaholela ekuqhekekeni nokunye ukukhubazeka kwe-aluminium.
- Umkhuba Wokuvimbela:Sebenzisa izindlela zokupholisa ezilawulwayo, ezifana nokusebenzisa ama-electrode apholise ngamanzi noma amakamelo okupholisa alawulwayo, ukuze uqinisekise izinga lokupholisa elihamba kancane nelifanayo ngemva kokushisela.
9. Ukuqeqeshwa Komsebenzi:
- Ukubaluleka:Ama-opharetha aqeqeshwe kahle abalulekile ekushiseleni okuphumelelayo kwenduku ye-aluminium.
- Umkhuba Wokuvimbela:Nikeza ukuqeqeshwa okuphelele ku-opharetha ngezinselele ezithile nezindlela ezihamba phambili zokushisela i-aluminium rod.Qinisekisa ukuthi banolwazi mayelana nezinto zokusebenza nezinto ezisetshenziswayo.
Izinti ze-aluminium zokushisela zisebenzisa imishini yokushisela izinqe zidinga ukunakwa kwemininingwane kanye nokunamathela emikhubeni ethile ukuze kuvinjelwe ukukhubazeka kokushisela.Ukugcina inhlanzeko, ukulawula isimo sokushisela, ukuqinisekisa ukufaneleka nokuqondanisa okufanele, ukusebenzisa imingcele yokushisela efanele, ukugcina ama-electrode, ukwenza izivivinyo zangaphambi kokushisela, ukwenza ukuhlolwa kwe-post-weld, ukulawula ukupholisa, nokuhlinzeka ngokuqeqeshwa komqhubi kuyizinyathelo ezibalulekile zokuvimbela.Ngokulandela lezi zinqubo, opharetha bangakhiqiza ama-welds angenasici futhi bathole imiphumela yekhwalithi ephezulu ezinhlelweni zokushisela ze-aluminium rod butt.
