Seamless ofERW simbi pombiyakakamurwa kuita geometric isina musono uye yemuviri isina musono.Geometric isina musono yeERW simbi pombi ndeyekubvisa mukati uye kunze maburrs.

Sezvo chimiro chemukati burr yekubvisa sisitimu uye chishandiso chekuenderera mberi nekuvandudza uye kukwana, yepakati uye yakakura dhayamita yesimbi pombi mukati mekubvisa burr chave chinhu chakanaka.Mukati meburr inogona kudzorwa mu -0.2mm ~ + O.5mm saka.Zvinoreva kune yemuviri isina musono weld microstructure mukati, pane musiyano pakati peiyo base zvinhu uye weld nzvimbo inokonzeresa kuderera kwemagetsi zvivakwa, kudiwa kwekutora matanho kuti ive yakafanana uye inowirirana tekinoroji.ERW simbi pombi ndeyepamusoro-frequency welding thermal process uye inokonzeresa tembiricha gradient, iri padyo nemupendero wechubhu uye ichigadzira nzvimbo yakanyungudutswa, iyo semi-yakanyungudutswa zone, kupisa nyama, nzvimbo yakajairwa, nzvimbo dzisinganyatso kujaira, nzvimbo dzinodziya. yenzvimbo yenzvimbo.Iyo yakawedzera kupisa zone tishu nekuda kwekupisa tembiricha pamusoro pe1000℃, iyo austenite tsanga inokura zvinoshamisa mumamiriro ekutonhora ichaita yakaoma uye brittle coarse crystalline chikamu, kunze kwekuvapo kwekushisa gradient kunoburitsa welding kusagadzikana.Nekudaro, kuumbwa kweiyo weld zone yakaderera pane base base simbi mechanical zvimiro zvemamiriro ezvinhu iri kuburikidza nemuviri isina musono weld kupisa kupisa maitiro ayo anoshandisa yemuno yakajairwa induction yekudziya mudziyo ichave weld nzvimbo inodziya kuAC3 (927).℃), ipapo 60m kureba, kumhanya 20m / min panguva yekutonhora kwemhepo, kutonhora kwemvura kana zvichidikanwa.Iyi nzira inoshandiswa kuzadzisa kubviswa kwekushushikana, kupfava uye kunatsiridza sangano kuvandudza HAZ mechanical properties zvinangwa.Parizvino, chikamu chepasi rose cheERW chakashandiswa zvakanyanya kugadzira weld chakawana mhedzisiro yakanaka.Hunhu haugone kukakavara kuti kwete chete ERW pombi welds uye weld coefficient ye1, kuzadziswa kwemasangano ematunhu e weld uye base simbi yemachisi.
