Umbhobho we-ERW kunye nombhobho we-LSAW yomibini yimibhobho edityanisiweyo ethe tye, esetyenziselwa ubukhulu becala ukuthutha ulwelo, ingakumbi imibhobho yomgama omde ye-oyile nerhasi. Umahluko omkhulu phakathi kwezi zimbini yinkqubo ye-welding. Iinkqubo ezahlukeneyo zenza umbhobho ube neempawu ezahlukeneyo kwaye zifanelekile kwiimeko ezahlukeneyo zesicelo.

Ityhubhu ye-ERW isebenzisa i-welding ye-high-frequency resistance welding kwaye isebenzisa iikhoyili zentsimbi eziqengqelekayo zebroadband njengezinto ezikrwada. Njengomnye weyona mibhobho esetyenziswa kakhulu namhlanje, ngenxa yokusetyenziswa kwemichilo yentsimbi eqengqelekayo / iikhoyili ezineyunifomu kunye nemilinganiselo echanekileyo epheleleyo njengezinto ezibonakalayo, ineenzuzo zokuchaneka komgangatho ophezulu, ubukhulu bodonga obufanayo, kunye nomgangatho omhle womphezulu. Umbhobho uneenzuzo zomthungo omfutshane we-weld kunye noxinzelelo oluphezulu, kodwa le nkqubo inokuvelisa kuphela imibhobho encinci kunye ne-medium-diameter ebhityileyo enodonga (kuxhomekeke kubungakanani bentsimbi okanye ipleyiti yentsimbi esetyenziswa njengento ekrwada). I-weld seam ithande ukuba namabala angwevu, awaxutywanga, iigrooves Iziphene zeCorrosion. Iindawo ezisetyenziswa kakhulu ngoku yirhasi yasezidolophini kunye nothutho lwemveliso yeoli ekrwada.

Umbhobho we-LSAW wamkela inkqubo yokudibanisa i-arc emanzini, esebenzisa ipleyiti enye ephakathi njengento eluhlaza, kwaye yenza i-welding yangaphakathi nangaphandle kwindawo ye-welding kwaye yandise ububanzi. Ngenxa yoluhlu olubanzi lweemveliso ezigqityiweyo zisebenzisa iipleyiti zentsimbi njengezinto ezikrwada, iiwelds zinokuqina okuhle, iplastiki, ukufana kunye nokubumbana, kwaye zineenzuzo zobukhulu bombhobho omkhulu, ubukhulu bodonga lombhobho, ukumelana noxinzelelo oluphezulu, ukumelana nobushushu obuphantsi kunye nokumelana nomhlwa. . Xa kusakhiwa umgangatho ophezulu, ukuqina, umgangatho ophezulu weoli kunye nemibhobho yerhasi, uninzi lwemibhobho yentsimbi efunekayo iyimibhobho edityanisiweyo enobubanzi obukhulu enodonga oluthe tye-umthungo wearc edityanisiweyo. Ngokomgangatho we-API, kwimibhobho emikhulu ye-oyile nerhasi, xa udlula kwindawo yoMgangatho woku-1 kunye noDidi 2 njengeendawo zealpine, amazantsi olwandle, kunye neendawo ezixineneyo zasezidolophini, imibhobho edityanisiweyo ye-arc edityanisiweyo ethe tye kuphela kohlobo lwemibhobho echongiweyo.
