Njengoko iimpawu ezintle zemibhobho yentsimbi engenasitali ziya kusiba ngakumbi kwaye zaziwa ngokubanzi, imibhobho yentsimbi engenasiseko ziye zasetyenziswa ngokubanzi kumashishini ahlukeneyo. Nangona kunjalo, ngenxa yeendleko zokuveliswa, imibhobho yentsimbi engenasitayile inentsebenzo enokuthelekiswa nemibhobho yentsimbi engenamthungo kwaye yamkelekile ngokubanzi. I-Hingao Tech (Matshini weSeko), Ngubani oneminyaka engama-20 yamava okuvelisa ishishini eliqaqambileyo I-Stainess yentsimbi yentsimbi ye-Wedld Bid ye-Bedld Bid , namhlanje sazisa amanyathelo okhuseleko kwimisebenzi ye-welding, ukuze ukwazi ukufumana ukumelana nokuziphatha okungcono kwemibhobho yentsimbi engenasitayile.
I-Dealis yamanyathelo okukhula kwe-welding
Inxenye enye
I-1. Ungaze uyikhuphele i-arc ngokungacwangciswanga kumphezulu wentsimbi engenasitayile, kungenjalo uya kubangela i-pume yendawo kumbhobho. Ukutshiswa kwendawo kumphezulu wombhobho ngumthombo we-irrosion, ngakumbi Umgca we-typeel yentsimbi engenasitayile ekufuneka isetyenziswe kumashishini afuna ukumelana nokunganyangeki okuphezulu, ezinjengeziselo, amayeza, ioyile kunye negesi, njalo njalo.
2. Nikela ingqalelo yokuhlengahlengisa isantya sokusebenza somgca wemveliso. Ukuba ubungangamzi usukele ngesantya esiphezulu kwaye ungawutyesheli umgangatho we-welding, isiphumo se-welding asizukukhathalela.
3. I-Welding Rod esetyenziselwa i-welding ye-welding kufuneka ifane nentonga ye-welding esetyenziswa ngexesha le-welding, kwaye ayivunyelwanga ukuyibuyisela nge-rod yentsimbi.
4. Phambi kwentsimbi yentsimbi engenasitayile yenziwa kwaye yenzelwe idyokhwe, okanye emva kokuba yenziwe ityhubhu, kufuneka kubekho i-tube, makungabikho kukhala, amanqaku e-ARC, amabala, kunye ne-slates, kunye ne-slates, kunye ne-slates, kunye ne-slates, kunye ne-slates, kunye ne-slag crust emva kokubamba kumphezulu. Ngaphandle koko, oku kuyakwandisa ukuvela kwendawo engaphezulu kwentsimbi, ekufuneka iqwalaselwe. Singafaka isixhobo sokwazisa ngemvume kwindawo engaphambili yecandelo lokwakha. Esi sakhiwo sincinci sinokukunceda ukususa iibhubhatha kwimiphetho ye-Strip, kwaye kwangaxeshanye senze umtya omangalisayo kwaye kube lula ukubumba.
I-5. Kwimibhobho ye-Weldion ye-Weldion enemibhobho yemveliso ephezulu yenkqubo, abavelisi abafanelekileyo banokuthatha isigqibo sokuxhobisa izixhobo ezibonakalayo ezikhanyayo. Ityhubhu yentsimbi engenasimo emva kokuqaqanjelwa i-Anneng ayikwazi kuphelisa uxinzelelo loxhaphazo. Emva kokuthimba, ifilimu emnyama kunye ne-iyunifomu ye-oxcom enokusekwa kumphezulu wombhobho wentsimbi ukukhusela intsimbi yangaphakathi kwi-oxidation kunye ne-corosion.
Inxenye yesibini
6. Xa i-welding igqityiwe okanye iphazamiseka, ukwenzela ukuthintela ii-arc craters okanye ii-rock, ii-ccc craters kufuneka zizaliswe.
7. Xa i-welding, i-wellomen kufuneka inxibelelane ne-wire emhlabeni ukuthintela ukunxibelelana kakubi phakathi kwendalo kunye ne-wire ye-wire, okukhokelela kwi-ARC itshisa intsimbi engenasimo kwaye ichaphazele ukunganyangeki kwentsimbi engenasigaba.
I-8. Ukwenzela ukuthintela ikharbon okanye ezinye izinto zokungcola ekubeni zidityaniswe kwi-WODld ngexesha le-Welding kwaye ichaphazela ukunganyangeki kwe-corrosion kunye nokucoca umtya wensimbi ngaphakathi kwe-20 ~ 30mm kumacala omabini ngaphambi kokuba i-welding. Unokukhetha ukufaka isixhobo sentshayelelo esemgangathweni kwindawo engaphambili yecandelo le-welding.
9. Xa itori okanye ihambisa umtya wentsimbi engenanto, akucetyiswa ukuba ikhuphe ngentsimbi eqhelekileyo ukukuphepha ukungcoliseka kwezinye ii-osis ezifana ne-rust kunye nokunye ukungcola.
I-10. Khusela ukukrwada okanye ukukrwada kumphezulu wemibhobho yentsimbi engenasitayile xa kusekho izixhobo zokusebenza ze-pile zokusebenza. Umaleko wokukhusela owukhuni unokusongelwa kwi-rack.
Inxalenye yesithathu
11. Xa umbhobho wentsimbi engenanto uqhinyiwe, kuyathintelwa ukuya kuqhuba ngokuthe ngqo nge-hammer ukuya kuthintela iidemon kumphezulu wombhobho. Ngaphandle koko, ukumelana nokunganyangeki kuya kuchaphazeleka kakhulu.
12. Kungcono ukusebenzisa ukucinezela okubandayo ukwenza intloko yokutywina kunye namanye amalungu esikhongozeli, kunokuba ucinezeleke. Ukuba i-short foring inyanzelekile, utshintsho ekuchanyoneni kokunganyangeki kufuneka ukhangele kwaye unyango olunomsindo kufuneka lwenziwe.
14. Xa intsimbi engenasigaba iphantsi kwe-Pred-Weld-Wible ye-Weld, ayifanelekanga ukuba ishiye ioyile kunye nobunye ubumdaka kumphezulu wensimbi ngaphambi kokufudumeza. Kufuneka icocwe ukuba iphephe ukuphathwa gadalala ngexesha lokufudumeza. Ngaphandle koko, ayiyi kuchaphazela kuphela ifuthe elihleliweyo, kodwa lifinyeze izixhobo zobomi bezixhobo eziphilayo kwaye zinyuse iindleko zesondlo. Cinga ukongeza isixhobo sokucoca kunye nokomisa ngaphambi kwenkqubo yokwazisa. Isixhobo sisebenzisa amanzi ashushu ukucoca umphezulu wombhobho, kwaye emva koko ngokukhawuleza umoya owomileyo ngombhobho womoya wokugcina umbhobho ococekileyo nowomileyo. Iqondo lobushushu lokufudumeza kufuneka liyiyunifomu. Xa usenza unyango loncedo loxinzelelo ngaphezulu kwe-800 ~ 900 ℃, amaqondo obushushu kufuneka akhuliswe ngokuthe ngcembe ngaphantsi kwe-850 ℃. Nangona kunjalo, xa iqondo lobushushu lifikelela kwi-850 ° C okanye ngaphezulu, iqondo lobushushu liza kukhawulezile ukuba liphephe utyekelo lweenkozo zekristali ukuba zinyuke.
15. Unyango lomphezulu wemibhobho yentsimbi engenasimo enjengokufuthi, ipoliding, ukuthathwa kunye nokudluliselwa kufuneka kuthathwe nzulu. Inkqubo yonyango kufuneka ihambelane neenkqubo zokusebenza. Umgangatho kukuba umphezulu wensimbi yi-silvey efanayo.
