Ithoshi yokushisela iyithoshi yokushisela igesi ekwazi ukuvutha ngogesi futhi inomsebenzi wokukhiya.
Ngeke ilimaze ithiphu le-weld uma lisetshenziswa ngokuqhubekayo.
Yiziphi izingxenye eziyinhloko zethoshi lokushisela?
Yiziphi izinyathelo okufanele zithathwe lapho usebenzisa amathoshi okushisela?
Ungakhetha kanjani ithoshi yokushisela?
Yiziphi izingxenye eziyinhloko zethoshi lokushisela?
1. Imbobo yocingo. Yaziwa nangokuthi ithiphu yokuxhumana futhi ngokuvamile iqukethe ithusi elimsulwa kanye nethusi le-chrome. Ukuze kuqinisekiswe ukuqhutshwa kahle kagesi kwethoshi lokushisela, ukunciphisa ukumelana nocingo phambili nokuqinisekisa i-centrifugation, ububanzi bebhore elingaphakathi le-nozzle ye-welding wire kufanele kukhethwe ngokuvumelana nobubanzi bocingo lokushisela. Uma ukuvuleka kukuncane kakhulu, ukumelana nocingo phambili kuphezulu. Uma ububanzi bembobo bukhulu kakhulu, isiphetho sentambo eshiselwe siqine kakhulu, okuholela ekushiseleleni okungalingani kanye nokuvikelwa okubi. Ngokuvamile ububanzi bocingo lwenozi bucishe bube ngu-0.2 mm ubukhulu kunobubanzi bocingo.
2. Shunt. I-shunt iqukethe i-ceramics evikelayo enezimbobo ezincane ezisatshalaliswe ngokulinganayo. Ngemuva kokuthi igesi yokuzivikela efafazwe ithoshi yokushisela idlulile i-shunt, ifafazwe ngokulinganayo kusuka ku-nozzle ku-laminar current, engathuthukisa umphumela wokuzivikela.
3. Ikhebula lekhebula. Ingaphandle lekhebula leshubhu elingenalutho liyipayipi le-rubber insulating, futhi kukhona amapayipi asentwasahlobo, ikhebula le-copper conductor, amapayipi egesi avikelayo kanye nemigqa yokulawula. Ubude obujwayelekile bungamamitha ama-3. Uma kudingeka, kungasetshenziswa ishubhu elingenalutho elingu-6 m ubude. Iqukethe isikulufu sasentwasahlobo, i-insulation housing kanye nocingo lokulawula.
Yiziphi izinyathelo okufanele zithathwe lapho usebenzisa amathoshi okushisela?
(1) Ungalokothi uthinte ikhanda likashise ngemuva kokuthi ithoshi yokushisela selixhunyiwe. Uma uyithinta ngephutha, izosha nakanjani futhi ibangele amabhamuza, ngakho-ke udinga ukuyihlanza ngokushesha.
(2) Ngemuva kokusetshenziswa isikhathi eside, kunemininingwane ekhanda lethoshi lokushisela futhi kufanele lihlanzwe ngelesula ukuze lihlale lihlanzekile.
(3) Uma i-weld burner isendaweni yokushisela, qaphela ukuthi ungazithinti izinto eziseduze nesitendi;
(4) Ngemva kokusebenzisa ithoshi yokushisela, donsa ipulaki bese ulinda imizuzu eyishumi ukuze liphole ngaphambi kokulikhipha.
Ungakhetha kanjani ithoshi yokushisela ilangabi?
Izibasi ezisetshenziselwa ukushisela igesi ziyefana nalezo ezisetshenziselwa ukushisela igesi. Kunezinhlobonhlobo zokucaciswa, amanani ajwayelekile, imiklamo, elungele amathoshi okushisela azenzakalelayo kanye ne-semi-automatic, umoya opholile kanye namanzi apholiswa. Nakuba igesi evikelayo ipholile kakhulu lapho idlula ithoshi lokushisela, inomphumela wokupholisa kuthoshi lokushisela, ithoshi lokushisela elipholile emoyeni lokupholisa lincike ekukhishweni kokushisa emoyeni ozungezile. Ithoshi yokushisela ikhethwa ikakhulukazi ngokusho kwe-welding current kanye negesi yokuzivikela esetshenzisiwe. Izibasi ezipholiswe ngamanzi ngokuvamile zisetshenziselwa imifudlana engu-500 Ampere noma ngaphezulu. Amanye amathoshi okushisela asakhetha izibasi ezipholiswe ngamanzi lapho amandla okushisela asetshenziswayo engaphansi kwama-ampere angu-500.
