Inkonzo yokunyathela imibhobho yentsimbi ye-JIS G3454 ERW yinkalo ebalulekileyo yokwenziwa kunye nokuveliswa kwemibhobho yentsimbi ye-ERW. I-JIS G3454 yiMigangatho yoShishino yaseJapan echaza imibhobho yentsimbi yekhabhoni yenkonzo yoxinzelelo oluphezulu. Umbhobho wentsimbi we-ERW (ukumelana nombane odibeneyo) wenziwa yinkqubo apho imiphetho yamacwecwe entsimbi okanye imicu ifudunyezwa kwaye idityaniswe phantsi koxinzelelo, yenze umbhobho ongenamthungo noqinileyo. Iinkonzo zokunyathela ezibandakanyekayo ekuvelisweni kwemibhobho yentsimbi ye-JIS G3454 ERW zidlala indima ebalulekileyo ekuqinisekiseni umgangatho kunye nokuthembeka kwale mibhobho. Iinkonzo zokunyathela ziquka ukusetyenziswa koomatshini abanoxinzelelo oluphezulu ukwenza imibhobho ngokwemilinganiselo kunye neenkcukacha ezifunekayo. Le nkqubo iqinisekisa ukuba umbhobho uneziphelo ezigudileyo nezichanekileyo, kunye nobukhulu bodonga obuhambelanayo kulo lonke ubude bawo. Enye yeenzuzo eziphambili zeenkonzo zokucinezela imibhobho yentsimbi ye-JIS G3454 ERW kukukwazi ukuvelisa imibhobho ngokuchaneka okugqwesileyo kunye nokuthembeka kwe-weld. Iinkonzo zokunyathela zivumela ulawulo oluqinileyo kwinkqubo yokuvelisa, ukuqinisekisa ukuba umbhobho uhlangabezana nemigangatho kunye neenkcukacha ezifunekayo. Ukongeza, ukusetyenziswa koomatshini abaxinzelela phezulu ngexesha leenkonzo zokustampa kunceda ukuvelisa iipayipi ezinamandla angaqhelekanga kunye nokuqina, nto leyo eyenza zifaneleke kwiintlobo ngeentlobo zezicelo kumashishini afana neoyile negesi, ulwakhiwo, kunye neemoto. Ukongeza, iinkonzo zokucinezela iipayipi zentsimbi ze-JIS G3454 ERW zinokuvelisa iipayipi ezigudileyo nezintle. Oomatshini abasetyenziswa kwiinkonzo zokustampa banokucola kwaye bacoce umphezulu wepayipi, nto leyo ephumela kwimveliso ebukekayo ngakumbi. Oku kubaluleke kakhulu kwizicelo apho iipayipi zibonakala okanye zibonakala njengoko kuphucula inkangeleko iyonke kwaye kuqinisekisa ukugqitywa komgangatho ophezulu. Ukuqukumbela, iinkonzo zokucinezela iipayipi zentsimbi ze-JIS G3454 ERW ziyinxalenye ebalulekileyo yenkqubo yokuvelisa, ukuqinisekisa ukuveliswa kweepayipi ezisemgangathweni ophezulu nezithembekileyo kwizicelo ezahlukeneyo zenkonzo yoxinzelelo. Iqinisekisa ukuchaneka kobukhulu, ukuthembeka kwe-weld, kunye neendawo ezigudileyo, okwenza ezi payipi zifaneleke kumashishini amaninzi kunye nokusetyenziswa.
