ERWyi-high-frequency resistance ukuwelda umthungo odityanisiweyo wepayipi;LSAWuntywiliselwe i-arc welding umthungo odityanisiweyo othe ngqo;Zombini zezombhobho odityanisiweyo othe tye, kodwa inkqubo yokuwelda yahlukile.Ngoko awukwazi ukuthetha enye yazo egameni lombhobho odityanisiweyo othe tye.Umbhobho wentsimbi eqhelekileyo ngakumbi SSAW– spiral welded umbhobho.Umthungo ophakamileyo othe tye (i-RW) ngokwenkqubo ye-welding yahlulahlulwe ngokwahlukileyo kwi-welding induction kunye nokumelana ne-welding iifom ezimbini, ngokusekwe kumthamo oshushu oqengqelekayo njengezinto ezikrwada, ngokuqhubeka nokubunjwa, ukugoba, ukuwelda, unyango lobushushu, ukulinganisa, ukolula, inkqubo yokusika.Xa kuthelekiswa ne-SSAW, ukuchaneka komgangatho ophezulu, ubukhulu bodonga obufanayo, umgangatho omhle womphezulu, uxinzelelo oluphezulu luyinzuzo yonke.Kodwa into engalunganga kukuba kuphela imveliso encinci yodonga oluncinci lombhobho obhityileyo, i-weld ilula ukumelana nesizukulwana, ukudityaniswa okungaphelelanga, iziphene zokubola komsele.Isetyenziswa kakhulu njengerhasi yesixeko, ukuthuthwa kweoyile ekrwada.

Izinto zombhobho wensimbi we-LSAW yintsimbi enye eshinyeneyo, intsimbi ekubunjweni okanye kumatshini wokubumba i-medium-voltage (umthamo), usebenzisa i-arc ye-arc enamacala amabini Uluhlu olugqityiweyo lwenkcazo yemveliso lubanzi, ukuqina kwe-weld, iplastiki, ukufana okuhle kunye nokuhambelana, kunye nobubanzi bombhobho omkhulu, ubukhulu bodonga, ukuchasana okunamandla kuxinzelelo oluphezulu, ukuxhathisa ubushushu obuphantsi, njl njl. Kulwakhiwo lwamandla aphezulu, ukuqina okuphezulu, umgangatho ophezulu weoli yomgama omde kunye nombhobho wegesi, ityhubhu yentsimbi ubukhulu becala ubukhulu obukhulu bodonga olungqindilili oluthe tye i-arc entywiliselweyo.Ngokwamalungiselelo omgangatho we-API kwimibhobho emikhulu ye-oyile kunye negesi, xa iindawo eziphakamileyo, ulwandle kunye nesixeko esinabemi kwiklasi ye-1, i-2, i-arc ethe tye i-arc efakwe emanzini yiyona kuphela eyenzelwe uhlobo lwetyhubhu.

Ngokweendlela zokwenza ezahlukeneyo zingahlulwa zibe: UOE/JCOE/HME.Imiqulu ye-spiral submerged arc (SSAW) ikwicala kunye nomgca osembindini wombhobho owenza i-Angle (ukulungiswa), ukubumba kunye nokuwelda, i-welding seam ibe yi-spiral, inzuzo kukuba inokuvelisa iinkcukacha ezahlukeneyo zombhobho wentsimbi. Ukucaciswa okufanayo, uluhlu lwezinto ezikrwada zikhulu, i-weld inokuphepha uxinzelelo oluphambili, imeko yoxinzelelo ilungile, into embi kukuba ubungakanani bejometri engalunganga, ubude be-weld xa kuthelekiswa nobude bomthungo othe tye, kulula ukuvelisa iintanda, i-porosity, i-slag, iziphene ze-weld. ezifana ne-welding, uxinzelelo lwe-welding yimeko yoxinzelelo lwe-tensile.Imithetho kunye nemimiselo ye-oyile jikelele kunye negesi yoyilo lombhobho omde wokuyila i-Spiral submerged arc ingasetyenziselwa kuphela iiklasi ezintathu, indawo yeklasi.I-4 yangaphandle le nkqubo iya kuphuculwa izinto eziluhlaza endaweni yentsimbi yentsimbi, ukuqulunqa kunye ne-welding, emva koko ukuwelda kunye nokuncibilika, ukwandisa okubandayo, emva kwe-welding, umgangatho we-welding usondele kwi-tube ye-UOE, ekhaya akukho nkqubo enjalo, ngulwalathiso lwe-welding. umzi-mveliso wethu ukuphucula."Irhasi yaseNtshona-mpuma" isasetyenziswa yimveliso yobugcisa bendabuko, kuphela ukwandiswa komngxuma wombhobho.I-United States, iJapan kunye neJamani, iyonke, i-SSAW embi, ayicingi ukuba ifanelekile ukusebenzisa i-trunk ye-SSAW;Inxalenye yeCanada kunye ne-Italiyane zisebenzisa i-SSAW, isiRashiya, isixa esincinci sokusetyenziswa kwe-SSAW, kwaye yenze imeko engqongqo ehambelanayo, ngenxa yezizathu zembali, uninzi lweziqu zasekhaya nazo kukusebenzisa i-SSAW.
