Ukushisela kuyindlela ebalulekile ekusebenzeni kwensimbi ehlanganisa izingcezu ezimbili zensimbi zibe isakhiwo esisodwa esiqinile. Insimbi eyakhiwe ngensimbi iyinsimbi embozwe ungqimba lwezinc, olunikeza ukuvikeleka okwengeziwe ekugqwaleni nokugqwala. Kodwa-ke, ukushisela insimbi eyakha insimbi kuletha izinselelo eziyingqayizivele ngenxa yezakhiwo zokumboza. Kulesi sihloko, sizohlola ukuthi ingabe kuyenzeka yini ukushisela insimbi eyakha insimbi, izinselele ongase ubhekane nazo, kanye nezinqubo ezihamba phambili zokuzuza ukushisela okuqinile nokuqinile.
Kungakhathaliseki ukuthi usebenza kuphrojekthi yokwakha, ukukhiqizwa kwezimboni, noma amaphrojekthi e-DIY, ukuqonda inqubo yokushisela yezinsimbi ezibalulekile kubalulekile ukuze uqinisekise ubuqotho nokuphepha kwamashisela akho.
Iyini i-Galvanized Steel?
Ngaphambi kokungena kwi-welding, kubalulekile ukuqonda ukuthi yini insimbi yashukumisa futhi kungani iziphatha ngendlela ehlukile kusukela steel evamile uma kuziwa Welding.
Insimbi eyenziwe nge-galvanized yenziwa ngokumboza i-carbon steel ngongqimba lwe-zinc. Le nqubo yokufaka uthayela yenzelwa ukuvikela insimbi ekugqwaleni nokugqwala, ikakhulukazi ezindaweni ezingaphandle noma ezindaweni ezithandwa umswakama. Isendlalelo se-zinc sisebenza njengesivikelo esivikelayo, esivimbela insimbi ekubeni i-oxidizing futhi yandise isikhathi sayo sokuphila.
Kodwa-ke, ukuba khona kwe-zinc kungabangela izinkinga ngesikhathi sokushisela. I-Zinc inezinga eliphansi lokuncibilika kunensimbi, futhi lapho uthayela owuthayela ushiselwa inqubo yokushisela, ungahwamuka futhi udale intuthu eyingozi. Ukwengeza, i-zinc ingathinta ikhwalithi ye-weld uma ingaphathwa kahle.
Ungakwazi yini Ukushisela Insimbi Eyisithako Ensimbi?
Yebo, kungenzeka ukushisela insimbi eyakhanyiswa ngensimbi. Kodwa-ke, le nqubo idinga ukunakekelwa okwengeziwe nokulungiselela ngenxa yokuba khona kwe-zinc coating. Izinselelo ezibalulekile yilezi:
I-Zinc Vaporization : Uma ushisela insimbi eyisithako, i-zinc coating izohwamuka ngenxa yokushisa kwenqubo yokushisela. Lokhu kudala intuthu enobuthi, engaba yingozi uma ihogeliwe. Izinyathelo ezifanele zokungenisa umoya nezokuphepha zibalulekile ukuze ugweme ukuhogela le ntuthu.
I-Weld Contamination : I-zinc ehwamukile ingaxubana nensimbi encibilikisiwe echibini lokushisela, okuholela ekungcoleni okungaba khona. Lokhu kungathinta ikhwalithi ye-weld futhi kuyenze ibe buthakathaka, okuholela ezindabeni zesakhiwo kumkhiqizo ophelile.
Ikhwalithi Ebi Yeld : I-Zinc ingabangela i-porosity, isimo lapho kwakheka izimbobo ezincane ku-weld bead, okwenza buthaka ukushisela. Ukuba khona kwe-zinc nakho kungaholela ekuqhekekeni noma e-brittle weld, ukunciphisa amandla ayo wonke.
Izinselele Ekushiseleni Insimbi Eyisithako Yakha Insimbi
Manje njengoba sesiyaqonda ukuthi ukushisela insimbi eyakha insimbi kungenzeka, ake sixoxe ngezinselelo ezithile ezihlobene nalolu hlobo lokushisela:
1. Intuthu nobuthi
Njengoba kushiwo ngaphambili, ukukhathazeka okuyinhloko lapho kushiselwa insimbi ewuthayela ukukhiqiza intuthu enobuthi. Lapho i-zinc ishisa ngesikhathi sokushisela, ikhiqiza umhwamuko we-zinc oxide, oyingozi empilweni yomuntu. Ukuchayeka isikhathi eside kule ntuthu kungaholela ku-metal fume fever, isimo esibonakala ngezimpawu ezinjengomkhuhlane njengokugodola, imfiva, nesicanucanu. Ngenxa yalesi sizathu, kubalulekile ukuqinisekisa ukungena kahle komoya endaweni yokushisela.
Ukuze unciphise ubungozi bokuhogela intuthu ye-zinc, hlala ugqoke okomshini wokuphefumula oklanyelwe ukusebenza ngensimbi futhi uqinisekise ukuthi indawo yokusebenza inomoya omuhle. Ukushisela endaweni evulekile noma ukusebenzisa i-exhaust system kunganciphisa kakhulu izingozi.
2. Pre-Welding Ukulungiselela
Ukuze ugweme izinkinga ezibangelwa ukumbozwa kwe-zinc, ezinye izinyathelo zokulungiselela ziyadingeka ngaphambi kokushisela insimbi eyakha insimbi:
Susa I-Zinc Coating : Enye yezindlela eziphumelela kakhulu zokunciphisa izinkinga ukususa ukugqoka kwe-zinc endaweni lapho i-weld izokwenziwa khona. Lokhu kungenziwa kusetshenziswa ibhulashi locingo, isondo lokugaya, noma izixazululo zamakhemikhali eziklanyelwe ukukhumula i-zinc ensimbi. Ukususa i-coating kuvimbela i-zinc ekuhwameni futhi ingcolise i-weld.
Hlanza Insimbi : Qinisekisa ukuthi izindawo zensimbi zihlanzekile futhi azinawo amafutha, uwoyela, noma imfucumfucu. Ukuhlanza okulungile kuqinisekisa ukuthi i-arc yokushisela ingahlanganisa kahle izinto ngaphandle kokuphazanyiswa kokungcola.
3. Izinkinga ze-Post-Welding
Ngisho nangemva kokushisela ngempumelelo insimbi eyakha insimbi, kungase kube nezinselele ezengeziwe okufanele kubhekwane nazo:
Ukushisela Okubuthakathaka : Ikhwalithi ye-weld ingase ibe sengozini ngenxa yokuqukethwe kwe-zinc, ikakhulukazi uma ingazange ikhishwe ngaphambi kokushisela. Ngemva kokushisela, kubalulekile ukuhlola amashisela ukuze uthole noma yiziphi izimpawu zobuthakathaka noma imifantu.
Ukugqwala Kwendawo Eshiselwe : Nakuba yonke ingxenye yensimbi eyisivikelo ivikelwe ekugqwaleni yi-zinc coating, insimbi esanda kuvezwa endaweni eshiselwe ijwayele ukugqwala uma ingaphathwa kahle. Kubalulekile ukufaka i-coat ukumelana nokugqwala endaweni eshiselwe ukugcina ubuqotho besakhiwo.
Uyishisela Kanjani Insimbi Eyisithako Ensimbi
Uma usulungele ukushisela insimbi eyakha insimbi, landela le mikhuba emihle kakhulu ukuze unciphise izinkinga futhi uqinisekise ukushisela okuqinile, okuhlala isikhathi eside:
1. Khetha Inqubo Yokushisela Elungile
Izindlela zokushisela ezifanele kakhulu zensimbi ethathiwe i-MIG (i-Metal Inert Gas) kanye ne-TIG yokushisela (i-Tungsten Inert Gas). Lezi zinqubo zifaneleka kangcono izinsimbi zegeji elincane njengensimbi ethathiwe. Zombili izindlela zivumela ukushisela okunembayo futhi zinciphise ubungozi bokushisa ngokweqile noma ukushiswa.
I-MIG Welding : Le ndlela isebenzisa intambo ephakelwa ngokuqhubekayo futhi ivame ukusetshenziselwa ukushisela ngokushesha. I-MIG welding ilungele izinto eziwugqinsi futhi inikeza ukulawula okukhulu kokufaka kokushisa.
I-TIG Welding : Le ndlela isebenzisa i-electrode ye-tungsten ukukhiqiza i-weld ehlanzekile, enembile. Ukushisela kwe-TIG kuhamba kancane kodwa kunikeza ukulawula okuhle kakhulu kokushisela, okuyenza ilungele izinhlelo zokusebenza ezidinga ukunemba okuphezulu.
2. Sebenzisa Igiya Elifanele Lokungenisa umoya kanye Nezokuphepha
Njengoba kushiwo ngaphambili, insimbi yokushisela ikhipha intuthu enobuthi. Ngaso sonke isikhathi qinisekisa ukuthi usebenza endaweni enomoya omuhle, okungcono kunesistimu yokukhipha intuthu. Gqoka okokuvikela okufanelekile komuntu siqu (i-PPE), okuhlanganisa isigqoko sokushisela, amagilavu, nomshini wokuphefumula. Lezi zinyathelo zokuphepha zizosiza ukunciphisa ubungozi bokuchayeka kuntuthu oyingozi.
3. Susa I-Zinc Coating
Ukuze uthole imiphumela engcono kakhulu, susa i-galvanized coating endaweni lapho i-weld izokwenziwa khona. Lokhu kungenziwa ngokusebenzisa ibhulashi locingo, amathuluzi abrasive, noma isixazululo sokuhlubula amakhemikhali. Ngokususa okokunamathelayo, unciphisa ingozi yokungcola futhi uqinisekise ukuthi insimbi engaphansi kwe-zinc ivezwa ukuze kube nokushisela okuqinile, okuhlanzekile.
4. Lungisa i-Welding Parameters
Uma ushisela insimbi, qaphela imingcele yakho yokushisela, njenge-voltage, i-amperage, nesivinini. Ukushisa okukhulu kakhulu kungabangela i-zinc ukuba ihwamuke futhi idale ukushisela okungazinzile. Qala ngezilungiselelo eziphansi futhi ulungise njengoba kudingeka ukuze uzuze ukushisela okubushelelezi, okuhlanzekile.
5. Ukuhlanza Nokuvikela Ngemva Kokushisela
Ngemva kokushisela, kubalulekile ukuhlanza indawo eshiselwe ukuze kukhishwe noma iyiphi insalela noma i-oxidation okungenzeka yakheke phakathi nenqubo. Ukufaka i-coating engagqwali endaweni eshiselwe kusiza ukuyivikela ekugqwaleni, iqinisekise ubude besikhathi sesakhiwo esishiselwe.
Isiphetho
Sengiphetha, ukushisela insimbi ebiyelwe ngensimbi kungenzeka, kodwa kudinga ukulungiswa okwengeziwe nokunakwa kwemininingwane ngenxa yezakhiwo eziyingqayizivele ze-galvanized coating. Ngokususa i-zinc coating, usebenzisa indlela yokushisela efanele, nokulandela izimiso zokuphepha, ungakwazi ukufeza i-weld ehlanzekile, eqinile. Kungakhathaliseki ukuthi usebenza kwizicelo zezimboni, amaphrojekthi wokwakha, noma ukuthuthukiswa kwekhaya, ukuqonda indlela yokushisela kahle insimbi ethathiwe kubalulekile ukuze uqinisekise impumelelo nokuphila isikhathi eside kwephrojekthi yakho.
Uma ufuna insimbi yekhwalithi ephezulu kanye neminye imikhiqizo yensimbi yephrojekthi yakho elandelayo, i-Shandong Sino Steel Co., Ltd. inikeza izinto ezisezingeni eliphezulu nezisombululo ukuhlangabezana nazo zonke izidingo zakho zokusebenza kwensimbi. Xhumana nathi namuhla ukuze ufunde kabanzi mayelana nemikhiqizo namasevisi ethu.
