Ehlabathini lemibhobho, igama elithi DSAW pipe lihlala livela kwiingxoxo malunga neemveliso zensimbi eziphezulu. DSAW, okanyeUkuwelda kwe-Arc kabini, yindlela esetyenziswa ukwenza imibhobho emikhulu edayamitha, ingakumbi kwishishini leoli nerhasi, nakwizinto zaselwandle nezakhiweyo. Le bhlog iya kujonga nzulu ukuba yintoni umbhobho we-DSAW, inkqubo yokuvelisa, kunye neenzuzo zayo.
Inkqubo yokwenziwa kombhobho we-DSAW ibandakanya amanyathelo amabini abalulekileyo: ukwenza imibhobho kunye ne-welding. Okokuqala, ishidi lensimbi elicwecwe lifakwe kwi-cylindrical shape. Imiphetho yephepha emva koko ilungiselelwe i-welding. I-DSAW iyingqayizivele kuba isebenzisa ii-arcs ezimbini ze-welding ezifakwe ngaphantsi kwe-granular flux. Oku akukhuseli kuphela i-weld ekungcoleni, kodwa iqinisekisa nokungena okunzulu, okubangela ukuba kubekho ibhondi eqinile, ehlala ixesha elide.
Enye yeenzuzo eziphambili zemibhobho ye-DSAW kukukwazi kwabo ukumelana noxinzelelo oluphezulu kunye neemeko ezingqongileyo ezingqongileyo. Oku kubenza balungele ukuthutha ioli kunye negesi kwimigama emide, apho ukuthembeka kungundoqo. Ukongezelela, imibhobho ye-DSAW iyaziwa ngobunzima bodonga obufanayo, obunegalelo ekuthembekeni kwesakhiwo kunye nokusebenza.
Enye inzuzo yeUmbhobho we-DSAWkukuba iyonga imali. Le nkqubo yokuvelisa inokuvelisa umbhobho omkhulu we-diameter ngexabiso eliphantsi kunezinye iindlela, ezifana nombhobho ongenamthungo okanye i-ERW (i-electric resistance welded) umbhobho. Oku kwenza umbhobho we-DSAW ube yindlela enomtsalane kumashishini amaninzi ajonge ukulinganisa umgangatho kunye nohlahlo lwabiwo-mali.
Ukuqukumbela, imibhobho ye-DSAW iyinxalenye ebalulekileyo kumacandelo ahlukeneyo, ngakumbi amandla kunye neziseko zophuhliso. Ulwakhiwo lwabo olumagingxigingxi, ukusebenza kakuhle kweendleko, kunye nokukwazi ukumelana neemeko ezinzima kubenza babe lolona khetho luphezulu kwizicelo ezininzi. Ukuqonda inzuzo kunye nenkqubo yokuvelisa imibhobho ye-DSAW kunokunceda iinkampani zenze izigqibo ezinolwazi xa zikhetha isisombululo sombhobho kwiiprojekthi zabo.
