Tollayn toosan oo laba-geesood leh oo qarqadda arc alxanka leh ayaa ahDhuumaha JCOE. Dhuumaha birta tollayn toosan waxaa loo kala saaraa laba nooc oo ku salaysan habka wax soo saarka: soo noqnoqda sare tollayn birta birta toosan iyo arc welded toosan tollayn birta tuubooyinka JCOE. Tubooyinka birta ee tolsan ee toosan ee tolsan waxaa loo kala saaray UOE, RBE, JCOE,LSAW tuubooyinka birta, iyo wixii la mid ah oo ku salaysan hababka ay u sameeyaan. Habka wax-soo-saarka tuubooyinka JCOE waa mid toos ah, oo leh wax-soo-saar sare, kharash yar, iyo horumar degdeg ah.
Tuubbada JCOE waa mid ka mid ah hababka samaynta birta tollayn toosan, iyo sidoo kale mid ka mid ah qalabka. Shiinaha, GB/T3091-2008 iyo GB/T9711.1-2008 ayaa si weyn loo isticmaalaa, halka API-5L uu yahay heerka caalamiga ah. Dhuumaha JCOE waxaa ugu horrayn la soo saaray iyadoo la isticmaalayo alxanka arc laba-geesoodka ah. Si loo buuxiyo shuruudaha heerarka la xiriira, alaabtu waxay martaa habab badan sida foorarid, isugeyn, alxanka gudaha, alxanka dibadda, toosinta, iyo cidhifyada siman.
Mashruucyada dhuumaha qaada ee baaxadda weyn, mashaariicda gudbinta biyaha iyo gaaska, dhismaha shabakada dhuumaha magaalooyinka, dhismooyinka qaab dhismeedka birta, tuullaynta buundooyinka, dhismaha dawlada hoose, iyo dhismaha magaalooyinka dhamaantood waxay isticmaalaan tuubada JCOE.

Ma jiro laalaabka, dildilaaca, delamination, alxanka dhabta ah, arc jebinta, gubashada, ama cilladaha kale ee maxaliga ah kuwaas oo qoto dheer ka weecan hoose ee dhumucda derbiga ayaa loo ogol yahay gudaha gudaha iyo dibadda sagxada JCOE toosan tuubooyinka birta tollayn. Cilladaha kale ee maxaliga ah ee leh qoto dheer oo aan ka badnayn leexashada hoose ee dhumucda derbiga waa la oggol yahay.
