Ingenamthungo yeIpayipi lensimbi le-ERWihlukaniswe ngokwejometri engenamthungo futhi engenamthungo ngokomzimba.I-geometric engenamthungo yepayipi lensimbi ye-ERW iwukukhipha ama-burrs angaphakathi nangaphandle.

Njengoba ukwakheka kwesistimu yokususa i-burr yangaphakathi kanye nethuluzi lokuthuthukisa okuqhubekayo nokuphelela, ipayipi lensimbi elinobubanzi obuphakathi nendawo obukhulu ngaphakathi kokukhishwa kwe-burr kube yimali enhle.Ngaphakathi kwe-burr ingalawulwa ngo -0.2mm ~ + O.5mm ngakho.Kubhekiselwa kusakhiwo se-weld esingenamthungo esingaphakathi ngaphakathi, kunomehluko phakathi kwe-base material nendawo yokushisela okuholela ekwehleni kwezakhiwo zemishini, isidingo sokuthatha izinyathelo zokwenza ubuchwepheshe obufanayo nobungaguquki.Ipayipi lensimbi le-ERW elokushisela okushisayo okuyimvamisa ephezulu futhi okuholela ekukhuphukeni kwezinga lokushisa, eliseduze konqenqema lweshubhu futhi lenze indawo encibilikisiwe, indawo encibilikisiwe, izicubu ezishisa ngokweqile, indawo evamile, izindawo ezingajwayelekile ngokuphelele, izindawo ezishisayo. yesifunda sesici.Okushise ngokweqile izicubu zezoni ngenxa yezinga lokushisa elingaphezulu kwe-1000℃, okusanhlamvu kwe-austenite okukhule ngokuphawulekayo ezimweni zokupholisa kuzokwakha isigaba se-crystalline esiqinile ne-brittle, ngaphezu kokuba khona kwe-gradient yokushisa kuzoveza ukucindezeleka kwe-welding.Ngakho-ke, ukwakheka kwendawo yokushisela ephansi kunesisekelo sezakhiwo zensimbi zesimo kungenxa yenqubo yokwelapha ukushisa kwe-weld engenamthungo esebenzisa idivayisi yendawo evamile yokushisisa yokushisela izoshisela indawo ibe yi-AC3 (927).℃), bese kuba ngu-60m ubude, isivinini esingu-20m/min ngesikhathi sokupholisa umoya, ukupholisa amanzi uma kunesidingo.Le ndlela isetshenziselwa ukufeza ukuqedwa kokucindezeleka, ukuthambisa kanye nokucwenga inhlangano ukuze kuthuthukiswe izinjongo zezakhiwo zemishini ye-HAZ.Njengamanje, iyunithi ye-ERW ethuthukisiwe emhlabeni wonke isetshenziswe kabanzi ekucubunguleni i-weld ithole imiphumela emihle.Ikhwalithi ayinakuphikiswa ukuthi akugcini nje ngokushisela ipayipi le-ERW kanye ne-weld coefficient ye-1, ukugcwaliseka kwezinhlangano zesifunda ze-weld kanye nesisekelo sensimbi yomdlalo.
