Ukuphucula ukusebenza kakuhle kunye nomgangatho kubalulekile kwishishini lemveliso enzima elihlala litshintsha. Enye yezona nkqubela zibalulekileyo kwitekhnoloji yokuthunga evele kwiminyaka yakutshanje kukuthungwa kwe-arc engaphantsi komhlaba kabini (i-DSAW). Le teknoloji intsha ayiphuculi nje kuphela ukuqina kwesakhiwo sezinto ezithungiweyo, kodwa ikwayenza lula inkqubo yokuvelisa, nto leyo eyenza kube yinto etshintsha umdlalo kumashishini axhomekeke kwizinto ezinzima.
Eyona nto iphambili kwi-DSAW kukukwazi kwayo ukuvelisa ii-welds ezikumgangatho ophezulu ezineziphene ezincinci. Le ndlela ibandakanya ii-arcs ezimbini ezingcwatywe phantsi komaleko we-granular flux, ekhusela ichibi le-weld ekungcoleni nasekungcolisweni. Isiphumo se-weld ecocekileyo neyomeleleyo enokumelana nobunzima bezicelo zokwenziwa ezisebenza nzima. Oku kubaluleke kakhulu kwiinkampani ezivelisaisakhiwo esidityanisiweyo esenziwe ngokubandayoiindawo ezingenanto, njengalezo zichazwe kwimigangatho yaseYurophu ngeemilo ezijikelezileyo, ezisikwere okanye eziziingxande. Ezi ndawo zibalulekile kwiindlela ezahlukeneyo zokusebenza, kuquka ulwakhiwo, iziseko zophuhliso kunye noomatshini abanzima.
Esi sityalo sikwiCangzhou, kwiPhondo laseHebei, sibonisa ngokupheleleyo iingenelo ze-DSAW kwimveliso enzima. Sasekwa ngo-1993, esi sityalo sigubungela indawo yeemitha zesikwere ezingama-350,000 kwaye sineempahla ezipheleleyo ezingama-680 ezigidi zeeyuan. Sinabasebenzi abazinikeleyo abangama-680, esi sityalo sikhokela ekuveliseni iindawo ezingenanto ezakhiweyo ezikumgangatho ophezulu. Ngokudibanisa i-DSAW kwinkqubo yokuvelisa, esi sityalo siphucule kakhulu ukusebenza kakuhle kunye nomgangatho wemveliso.
Enye yezona nzuzo ziphambili ze-DSAW kukukhawuleza. Le nkqubo ivumela isantya esikhawulezayo sokuwelda kuneendlela zemveli, nto leyo enciphisa ixesha lokuvelisa. Oku kusebenza kakuhle kubalulekile kwimveliso enzima apho ixesha lidla ngokuba yinto ebalulekileyo. Ngokunciphisa ixesha lokuwelda, abavelisi banokwandisa imveliso kwaye bahlangabezane neemfuno zemarike ekhuphisanayo.
Ukongeza, umgangatho we-DSAW weld uhlala uphezulu rhoqo. Inkqubo ye-arc engaphantsi komhlaba inciphisa umngcipheko weziphene ezifana nokuqhekeka kunye nokufakwa kwezinto ezinokuphazamisa ukuthembeka kwesakhiwo semveliso yokugqibela. Oku kubaluleke kakhulu kwiindawo ezingenanto ezakhiwe nge-welded ezakhiwe ngokubandayo, ekufuneka zihlangabezane nemigangatho yomgangatho oqinileyo ukuqinisekisa ukhuseleko kunye nokuthembeka kwezicelo zazo. Isityalo saseCangzhou sisebenzisa obu buchwepheshe ukuqinisekisa ukuba iimveliso zaso azihlangabezani nje nemigangatho yoshishino, kodwa ziyadlula.
Ukongeza ekuphuculeni ukusebenza kakuhle kunye nomgangatho, i-DSAW ikwanceda ekongeni iindleko. Ngenxa yeziphene ezimbalwa, akukho mfuneko ingako yokuphinda kusetyenziswe, nto leyo ethetha ukuba abavelisi banokwabela izixhobo ngokufanelekileyo. Oku kuluncedo ngakumbi kwimveliso enkulu, apho iindleko zezinto kunye nabasebenzi zizinto ezibalulekileyo kwiindleko zemveliso iyonke.
Njengoko ishishini lokuvelisa izinto ezintsonkothileyo liqhubeka likhula, ukwamkelwa kwezobuchwepheshe obuphambili bokutywina ezifanai-arc engaphantsi kwamanzi edibeneyo kabiniiza kudlala indima ebalulekileyo ekubumbeni ikamva. Iinkampani ezityala imali kule teknoloji aziyi kuphucula kuphela ukusebenza kakuhle kodwa ziya kuphucula nomgangatho wemveliso, ngaloo ndlela zifumana isikhundla esiphambili kwimarike enokhuphiswano olukhulu.
Ngamafutshane, ukuwelda nge-arc engaphantsi kwamanzi kabini kuguqula imveliso enzima ngokuphucula ukusebenza kakuhle kunye nomgangatho. Esi sityalo sikwiSixeko saseCangzhou ngumzekelo obalaseleyo wendlela ubuchwepheshe obunokufakwa ngayo ngempumelelo kwinkqubo yemveliso, buvelise iindawo ezingenanto ezakhiweyo ezikumgangatho ophezulu ezihlangabezana neemfuno zoshishino lwanamhlanje. Njengoko abavelisi bezama ukugqwesa, ukwamkela ubuchwepheshe obutsha obufana ne-DSAW kuya kuba yinto ebalulekileyo kwimpumelelo kwiminyaka ezayo.
