Ukuphucula ukusebenza kakuhle kunye nomgangatho kubalulekile kwishishini lemveliso ehlala iguquka. Enye yezona nkqubela zibalulekileyo kwitekhnoloji ye-welding eza kuvela kule minyaka yakutsha nje kukuntywiliselwa kwe-arc welding (DSAW). Obu buchwephesha obutsha abuphuculi nje kuphela imfezeko yolwakhiwo lwamacandelo adityanisiweyo, kodwa lwenza lula inkqubo yokwenziwa kwemveliso, nto leyo eyenza ukuba itshintshe umdlalo kumashishini axhomekeke kwizinto ezinzima.
Embindini we-DSAW kukukwazi ukuvelisa iiwelds ezikumgangatho ophezulu ezineziphene ezincinci. Indlela ibandakanya ii-arcs ezimbini ezingcwatywe phantsi kwe-granular flux, ekhusela i-weld pool ekungcoleni kunye ne-oxidation. Isiphumo sisicoci, i-weld eyomeleleyo enokumelana nobunzima bezicelo zokwenziwa kolwakhiwo olunzima. Oku kubaluleke kakhulu kwiinkampani ezivelisayokubanda kwakheka welded lwesakhiwoamacandelo angenanto, njengalawo achazwe kwimigangatho yaseYurophu kwimilo engqukuva, yesikwere okanye exande. La macandelo abalulekile kwizicelo ezahlukeneyo, kubandakanywa ulwakhiwo, iziseko ezingundoqo kunye noomatshini abakhulu.
Efumaneka eCangzhou, kwiPhondo laseHebei, isityalo sibonisa ngokupheleleyo iingenelo ze-DSAW kwimveliso enzima. Yasekwa ngo-1993, isityalo sigubungela indawo ye-350,000 square metres kwaye ine-asethi ye-680 yezigidi zeeyuan. Ngabasebenzi abazinikeleyo abangama-680, lo mzi-mveliso uyinkokeli ekuveliseni amacandelo akumgangatho ophezulu ongenanto. Ngokudibanisa i-DSAW kwinkqubo yokuvelisa, isityalo siye saphucula kakhulu ukusebenza kakuhle kunye nomgangatho wemveliso.
Enye yeenzuzo eziphambili ze-DSAW kukukhawuleza. Inkqubo ivumela ukukhawuleza kwesantya se-welding kuneendlela zendabuko, ezinciphisa ixesha lokuvelisa. Oku kusebenza kakuhle kubalulekile kwimveliso enzima apho ixesha lihlala liyinto ebalulekileyo. Ngokunciphisa ixesha le-welding, abavelisi banokunyusa imveliso kwaye bahlangabezane neemfuno zemarike yokhuphiswano.
Ukongeza, umgangatho we-weld we-DSAW uhlala uphezulu. Inkqubo ye-arc ephantsi kwamanzi inciphisa umngcipheko weziphene ezifana ne-porosity kunye nokubandakanywa okunokuthi kuphazamise ukunyaniseka kwesakhiwo semveliso yokugqibela. Oku kubaluleke kakhulu kumacandelo angaphakathi adityanisiweyo adityanisiweyo, ekufuneka ahlangabezane nemigangatho engqongqo yomgangatho wokuqinisekisa ukhuseleko nokuthembeka kwezicelo zabo. Isityalo saseCangzhou sisebenzisa le teknoloji ukuqinisekisa ukuba iimveliso zayo azihlangabezani nemigangatho yoshishino kuphela, kodwa zigqithise.
Ukongeza ekuphuculeni ukusebenza kakuhle kunye nomgangatho, i-DSAW ikwanceda ukonga iindleko. Ngeziphene ezimbalwa, kukho imfuneko encinci yokuphinda kusetyenzwe, nto leyo ethetha ukuba abavelisi banokwaba izixhobo ngokufanelekileyo. Oku kunenzuzo ngakumbi kwimveliso enkulu, apho iindleko zempahla kunye nabasebenzi zizinto ezibalulekileyo kwiindleko zemveliso ngokubanzi.
Njengoko ishishini lokuvelisa elinzima liqhubeka likhula, ukwamkelwa kobuchwepheshe be-welding obuphambili njengeI-arc entywiliselwe kabini idityanisiweiya kuba nendima ebalulekileyo ekubumbeni ikamva. Iinkampani ezityala imali kobu buchwepheshe aziyi kuphucula ukusebenza kakuhle kuphela kodwa zikwaphucula umgangatho wemveliso, ngaloo ndlela zifumana isikhundla esiphambili kukhuphiswano lwentengiso.
Ngamafutshane, ukuwelda kwe-arc entywiliselwe kabini kuguqula imveliso enzima ngokuphucula ukusebenza kakuhle kunye nomgangatho. Esi sityalo kwisiXeko saseCangzhou ngumzekelo obalaseleyo wendlela itekhnoloji enokuthi idityaniswe ngayo ngokufanelekileyo kwinkqubo yokuvelisa, ivelise amacandelo akumgangatho ophezulu wezakhiwo ezingenanto ezihlangabezana neemfuno zoshishino lwanamhlanje. Njengoko abavelisi bazamela ukugqwesa, ukwamkela itekhnoloji entsha efana ne-DSAW kuya kubaluleka kwimpumelelo kwiminyaka ezayo.
