Yintoni umbhobho wentsimbi we-ERW? Umahluko omkhulu phakathi kwe-ERW yentsimbi yombhobho (i-Electric Resistance Welding, efinyeziweyo njenge-ERW) kunye nombhobho wensimbi ongenamthungo kukuba i-ERW inomthungo we-weld, ekwasitshixo kumgangatho we-ERW wentsimbi yombhobho. Modern ERW iteknoloji yokuvelisa umbhobho yentsimbi kunye nezixhobo, ngenxa ngamazwe Ngokukodwa kunye neenzame unremitting eUnited States kunye namanye amazwe kule minyaka idlulileyo, i seamlessness imibhobho yentsimbi ERW iye yasonjululwa ngokwanelisayo. Abanye abantu bohlula-hlula ukungabinamthungo kwemibhobho yentsimbi ye-ERW ibe kukungabinamthungo kwejometri kunye nokungabinamthungo komzimba. Ukungabinamthungo kwejiyometri kuthetha ukucoca imibhobho yentsimbi ye-ERW. I-burrs yangaphakathi nangaphandle. Ngenxa yokuphuculwa okuqhubekayo kunye nokuphuculwa kwesakhiwo senkqubo yokususa i-burr yangaphakathi kunye nezixhobo zokusika, i-burrs yangaphakathi yeebhobho zetsimbi ezinkulu kunye ne-medium-diameter ziye zacutshungulwa ngcono. I-burrs yangaphakathi inokulawulwa malunga ne-0.2mm~+O.5mm kwaye ikhululekile ngokwasemzimbeni. I-Seamization ibhekisela kumahluko phakathi kwesakhiwo se-metallographic ngaphakathi kwe-weld kunye nesiseko sesinyithi, okubangelwa ukuhla kweempawu zomatshini wendawo ye-weld. Kufuneka kuthathwe amanyathelo ukuze ifane kwaye ihambelane. I-high-frequency welding thermal process ye-ERW yemibhobho yentsimbi yenza ukuba ityhubhu ingabi nanto. , ezinye iinkalo zeempawu. Phakathi kwabo, isakhiwo sommandla oshushu kakhulu yi-austenite ngenxa yokushisa kwe-welding ngaphezu kwe-1000 ° C. Iinkozo zikhula ngokukhawuleza, kwaye isigaba sekristale esiqinileyo kunye ne-brittle siya kwenziwa phantsi kweemeko zokupholisa. Ukongeza, ubukho beqondo lobushushu buya kuvelisa uxinzelelo lwe-welding. Oku kubangela imeko apho iimpawu zemishini yendawo ye-weld ziphantsi kunezo zixhobo ezisisiseko kunye nokunyanzeliswa komzimba kufezekiswa. Kungenkqubo yonyango yesiqhelo yobushushu bomthungo we-weld, oko kukuthi, ukusebenzisa isixhobo sokufudumeza esiphakathi ukufudumeza ukufudumeza indawo ye-weld seam ukuya kwi-AC3 (927°C), kwaye emva koko wenze inkqubo yokupholisa umoya ngobude obungama-60m. kunye nesantya se-20m / min, kunye nokupholisa kwamanzi xa kuyimfuneko. Ukusetyenziswa kwale ndlela kunokufezekisa ukuphelisa uxinzelelo, ukuthambisa kunye nokucokisa isakhiwo, kunye nokuphucula iimpawu zoomatshini ezibanzi zommandla ochaphazelekayo we-welding, okwangoku, iiyunithi ze-ERW eziphambili zehlabathi ziye zamkela le ndlela yokucubungula i-welds, kwaye ziphumelele. iziphumo ezilungileyo. Imibhobho yentsimbi ye-ERW esemgangathweni ayikho kuphela I-weld seam engakwazi ukuchongwa, kwaye i-coefficient ye-weld seam ifikelela kwi-1, ifezekisa umdlalo phakathi kwesakhiwo sendawo ye-weld kunye nesiseko sezinto. Imibhobho yentsimbi ye-ERW inenzuzo yokusebenzisa iikhoyili eziqengqelekayo ezishushu njengemathiriyeli ekrwada, kwaye ubukhulu bodonga bunokulawulwa ngokufanayo malunga ne-± 0.2mm. Iziphelo ezimbini zombhobho wensimbi Ngokomgangatho we-APl waseMelika okanye umgangatho we-GB / T9711.1, uneenzuzo zokuphela kwe-beveling kunye nokuhanjiswa kobude obusisigxina. Kwiminyaka yakutshanje, iiprojekthi ezahlukeneyo zothungelwano lwemibhobho yerhasi yendalo kunye neenkampani zegesi ziye zamkela ngokubanzi imibhobho yentsimbi ye-ERW njengeyona mibhobho yentsimbi kuthungelwano lwemibhobho yasezidolophini.
