Isikhokelo esibanzi sibonisa intshukumo yeIplatimu ye-China, evavanya izicelo zayo ezahlukeneyo, eziqwalaselwa kakhulu kwiiprojekthi eziphumeleleyo, kwaye abadlali abaphambili babumba lo mzi mveliso ubalulekileyo. Sinemicimbi yezobugcisa, ukuthotyelwa komthetho, kunye nezona ndlela zilungileyo ukuqinisekisa imisebenzi efanelekileyo nekhuselekileyo.
ElunxwemeniIplatiform yeldingIbonisa imiceli mngeni eyodwa ngenxa yendawo enobunkunyane yaselwandle kunye nemigaqo yokufuna ukhuseleko. Izixhobo ezihlala zisetyenziswa zibandakanya izabelo zensimbi ezifuna ukunyanzeliswa kweendlela ezikhethekileyo ze-wells ezifana ne-arc ene-arc ene-arc enama-ARC ye-Arc Ezi projekthi zinyanzelisa ulawulo oluqhelekileyo lomgangatho kunye nokubambelela kwimigangatho yehlabathi efana nezo zimiselweyo yi-DNV GL okanye i-ABS. Iinkampani ezikhethekileyo kule ndawo kufuneka zibe nobungcali ekwenzeni ngaphantsi kwamanzi kwaye zinezinto eziphezulu ze-welding ezinamandla okusebenza kwiimeko ezinzima. Ngolwazi oluthe kratya malunga nezixhobo ezithile kunye neendlela ezisetyenziswa kumaqonga aselunxwemeni, unokubonisana ngezixhobo zokunxulumana neWeling Welding kunye noPapasho lweShishini.
OnshoreIplatimu ye-ChinaIiprojekthi, ngelixa zingachazwanga kwizinto, zisafuna ukuchaneka kunye nokubambelela kwimigangatho yokhuseleko. La maqonga anokuba yinxalenye yezinto ezikwamashishini, amaziko emveliso, okanye kwiiprojekthi zeziseko zophuhliso. Iinkqubo ze-welding ezisetyenziswayo zinokuhluka ngokuxhomekeka kwiqonga leqonga kunye nezixhobo ezichaphazelekayo. Iindlela eziqhelekileyo zobuchule zibandakanya i-arc yegesi (gmaw), i-tungsten arc welc (i-GTEW), kunye ne-Arc ye-Arc ye-Arc ye-Arc ye-Arc welc (smaw). Ukuqinisekisa ukulungiswa okufanelekileyo, i-ramering ye-uplding, kwaye ihlolike ngokuchanekileyo kubalulekile kwixesha elide lexesha elide lale qonga.
Ukukhetha kwezinto zichaphazela ngokuthe ngqo inkqubo ye-welding kunye nokuqina kwemveliso yokugqibela. Izinto ezifana nokuchasana nokunganyangeki, ububanzi bomzimba, kunye nokungabinakho kufuneka kuqwalaselwe ngononophelo. Amandla aphezulu-amandla aphezulu (HSLA) i-HSLA isetyenziswa rhoqo ngenxa yamandla abo agqwesileyo kunye nokwabelana. Intsimbi engenasimo inokuba yimfuneko nakwizicelo ezithile ezifuna ukumelana nokungakhathali. Ukukhetha izixhobo zelungelo linyathelo lokuqala lokuqalisa ukuqinisekisa impumeleloIplatimu ye-Chinaiprojekthi. Ukhetho kufuneka luhlale lwenziwe ngokungqinelana nemigangatho efanelekileyo yeshishini kunye neekhowudi.
Uluhlu olubanzi lweenkqubo ze-welding uqeshiweIplatimu ye-China, nganye inezibonelelo zayo kunye nokusikelwa umda. Ukukhetha le nkqubo ilungisa kuxhomekeke kwizinto ezinje ngobuncwane bezinto ezibonakalayo, uyilo oluhlanganisiweyo, kunye nomgangatho we-WEld Wod. Ngelixa i-fcaw ihlala ithanda amacandelo aphezulu, i-GMAW kunye ne-GMAW ilungele izixhobo ezinembumbulu kunye neemeko ezifuna ukuchaneka okuphezulu. Ukuqonda ezi zinto zibalulekileyo kubaluleke kakhulu ekuqinisekiseni i-wels esebenzayo nephezulu. Kubalulekile ukuba kuqinisekiswe ukuba bonke abakwi-aldiders bafaneleke ngokufanelekileyo kwaye baqinisekisiwe ngokwemigangatho efanelekileyo.
Amanyathelo olawulo olusemgangathweni aphambiliIplatimu ye-ChinaIiprojekthi zokuqinisekisa ukuthembeka nokhuseleko. Oku kubandakanya uvavanyo lwangaphambi kokutya kunye nokulungiselela ngokudibeneyo, ukubek'esweni okwenyani kwenkqubo ye-welding, kunye ne-Post-Weld-Ild-Ild-Ild-Ild-Ild) ukufumana nasiphi na isiphene. Iindlela ezifana nokuhlolwa okubonakalayo, Uvavanyo lwe-radiagraphic (RT), Uvavanyo lwe-Ultrasonic (i-UT), kunye novavanyo lwe-magnetic (MT) zihlala zisebenza. Ukubambelela kwiMigangatho yeHlabathi kunye nezona ndlela zibalaseleyo zibalulekile ekuqinisekiseni ukhuseleko kunye nokuthembeka kwezakhiwo ezigqityiweyo. Inkqubo yolawulo lomgangatho wombane ibaluleke kakhulu kuyo yonke iprojekthi.
Ukukhetha umboneleli wenkonzo odumileyo we-welding kubalulekile ukuze uphumeleleIplatimu ye-ChinaIiprojekthi. Jonga iinkampani ezinerekhodi eqinisekisiweyo, enamava, kunye nokuzibophelela kumgangatho kunye nokhuseleko. Qinisekisa ukuba baneziqinisekiso eziyimfuneko kwaye bahambelana nemigangatho efanelekileyo yeshishini. Ukungasebenzi kakuhle kuyacetyiswa ngaphambi kokuba ubandakanyeke kuyo nayiphi na ikhontraktha. Kwabo bafuna iinkonzo ezisemgangathweni eziphezulu, cinga ukuxhaphaza abavelisi abasekwe kunye nabathengisiI-Botou Haiun Peetin Feene Comple Coul Co., Ltd., Inkampani eyaziwa ngokuzibophelela kwayo ekugqwesisweni kwesinyithi.
Ukuhambahamba komhlaba olawulayo yinto ebaluleke kakhulu yeIplatimu ye-China. Ukuthotyelwa kwemigangatho yesizwe neyehlabathi kubalulekile ukuphepha imicimbi yezomthetho kunye nokuqinisekisa ukhuseleko lweprojekthi. Qhelanisa nawe ngeekhowudi ezifanelekileyo kwaye kufuneka umntu ofanele ukubandakanyeke kweli shishini.
