ERW umbhobho weld imilo yecontour
Ngokwemigangatho ye-API SPEC 5L, uninzi lwezityalo zemveliso yasekhaya ngexesha lovavanyo lwe-SAW umbhobho weld tensile, uhlala ugcina ukuqiniswa kwe-weld, uvavanyo oluthe ngqo lwe-tensile ukusuka kuvavanyo olunqabile ukuphulwa kwe-welds imeko.Isizathu esiyintloko sinokubangelwa ubukho be-weld reinforcement.Umbhobho we-SAW, uthe ngaphezu kokuphezulu okanye ukomeleza okuphezulu, kwinjongo yokwandisa ubukhulu bendawo ye-weld, kunye nokwandisa amandla okwakhiwa kwe-weld, amandla ommandla we-weld (amandla esakhiwo ngokubanzi) ngaphezu kwamandla esiseko. iindawo zentsimbi.
Isalathiso SAW umbhobho weld Ukuqinisa indima enenzuzo kwi welding umbhobho we-ERW Weld izimisele ukucudisa ubukhulu, kwindawo ye-weld ukwenza ubukhulu obukhulu kunobunzima bezinto ezisisiseko, ukwandisa ukuya kwindawo yokuqinisa i-weld echatshazelwe lubushushu, ngoko ngaphakathi. Ukwenziwa kwe-welding burr ilungelelene ngokupheleleyo, yenze ummandla we-wavy ogudileyo wenguqu ukuphucula ukomelela kwesakhiwo sendawo ye-weld phakathi kwesiseko sentsimbi kunye neeweld zentsimbi.Okwangoku, ekubeni ubukhulu beentsimbi zemibhobho zinonyamezelo olukhulu, nokungazinzi kwenkqubo yokukhuhla ngenxa ye-glitch yangaphakathi, ekhokelela kwiqondo elithile le-welds ye-scratch groove, ayiyi kubangela ukuhla kwamandla e-weld.Ukongeza, i-weld kunye nesiseko sesinyithi soguqulo olugudileyo, uvavanyo lwe-ultrasonic lwe-weld alubangeli ukunyuka kwamazinga obuxoki.
Krwela i-welds yangaphakathi egudileyo kakhulu, i-weld kunye nesiseko soguqulo lwentsimbi egudileyo kakhulu.Ngokuqhelekileyo umbhobho wentsimbi ubukhulu bodonga yi-11.9mm, uluhlu olungqindilili lwe-extrusion welds ngokuqhelekileyo luqala ukusuka malunga ne-25mm ukuya nakweliphi na icala le-weld nganye, isahlulo se-weld emva kokususwa kwe-burr kunezinye iindawo zobunzima bezinto ezisisiseko malunga ne-10%.Ubungqingqwa obuncinci bombhobho, ukucudisa uluhlu olushinyeneyo lunokuncitshiswa, kodwa ubungakanani beendawo ezishinyeneyo ze-weld zolawulo jikelele 10% yobukhulu besiseko sezinto.
