Ekuthengeni izixhobo zoshishino,imibhobho engenamthungozisebenza njengezinto ezibalulekileyo ezinomgangatho ochaphazela ngokuthe ngqo ukhuseleko lweprojekthi. Imingcipheko inokuthotywa njani ngempumelelo ngexesha lenkqubo yokuthenga?
Ukuhlolwa okubonakalayo: Khangela amanqaku e-Weld
Okwenyaniimibhobho yentsimbi engenamthungozenziwe ngokubhoboza kunye nokuqengqeleka kweebhilidi zetsimbi ezijikelezayo, okukhokelela kwisakhiwo esingenamthungo. Nokuba igqitywe ngobuchule, imibhobho edityanisiweyo isenokuthi ithwale umkhondo wenkqubo yokwenziwa kwayo. Okokuqala, jonga umphezulu wombhobho ukuze ufumane amanqaku ahambelanayo, anokubonisa i-welds processed. Ukusebenzisa igilasi yokukhulisa, imibhobho edityanisiweyo idla ngokubonisa ukuguquguquka okungephi kwemibala okanye utshintsho kwimibhobho.
Enye indlela esebenzayo kukuphonononga i-cross-section kuzo zombini iziphelo. Imibhobho engenamthungo ibonisa ulwakhiwo olufanayo kulo lonke, ngelixa imibhobho edityanisiweyo ibonisa izakhelo zemetallographic ezahlukileyo kwindawo yeweld. Kwangaxeshanye jonga udonga lwangaphakathi: imibhobho edityanisiweyo isoloko igcina amanqaku e-welding okanye ii-burrs, ngelixa imibhobho yokwenyani engenamthungo ibonakalisa ubuphakathi obugudileyo, obufanayo.
Uvavanyo lweZandi: Indlela elula yokuchonga
Iimvavanyo zokucofa zibonelela ngendlela ethe ngqo yokuchongwa kwangaphambili. Ukubetha ngobunono umbhobho ngentonga yentsimbi. Imibhobho engenamthungo ivelisa isandi esimnandi, esindayo kunye nesandi esifanayo. Imibhobho edityanisiweyo, ngenxa ye-weld seam, ikhupha isandi esincinci esinokuhluka kwindawo ye-weld. Ngelixa le ndlela ingenakusebenza njengokuzimisela kokugqibela, iluncedo ekuhlolweni ngokukhawuleza kwindawo. Ukuba izandi ezingaqhelekanga zifunyenwe, uvavanyo olunzulu ngakumbi luyafuneka.
Uvavanyo lobuNgcali: Iindlela ezithembekileyo zoQinisekiso
Uvavanyo lwe-Ultrasonic yenye yezona ndlela ezinokwethenjelwa kakhulu zokwahlula iipayipi zensimbi ezingenamthungo ukusuka kwimibhobho edibeneyo. Iingcali ze-ultrasonic flaw detectors ziyakwazi ukubona ngokuchanekileyo ubukho be-welds. Nokuba imibhobho edityanisiweyo igqityezelwa ngobunono, uvavanyo lwe-ultrasonic lunokubonisa ukungaqhubeki kulwakhiwo lwemathiriyeli.
Uhlalutyo lwe-metallographic lumele eyona ndlela yenzululwazi yokuchonga. Ngokulungiselela iisampulu ze-metallographic ezivela kwiisampulu kunye nokuvavanya i-microstructure yazo phantsi kwe-microscope, imibhobho engenamthungo ibonisa i-microstructures engaguqukiyo, ngelixa imibhobho edityanisiweyo ibonisa iyantlukwano eyahlukileyo kwisakhiwo se-weld, iindawo ezichatshazelwe bubushushu, kunye nemimandla yesinyithi esisiseko.
Ukuqinisekiswa koXwebhu: Ukuphonononga iziQinisekiso zoMgangatho
Abavelisi abahloniphekileyo banikezela ngamaxwebhu abanzi omgangatho wemveliso, kubandakanywa izatifikethi zezinto eziphathekayo, iirekhodi zenkqubo yokuvelisa, kunye neengxelo zokuhlola. Waphonononge ngononophelo la maxwebhu, ngakumbi uqinisekise ukuba ikholamu yenkqubo yemveliso ichaza ukuveliswa “okungenamthungo”. Usenokucela isiqinisekiso somthengisi kumenzi.
Kutheni Khetha EHONG?
Ngeminyaka engama-20 yobuchwephesha bokuthumela ngaphandle kwentsimbi, singumthengisi othembekileyo weempawu zentsimbi zeTianjin kunye nelungu le-China Iron kunye ne-Steel Export Industry Alliance. Ubudlelwane bethu obucwangcisiweyo kunye nezixhobo eziphambili zentsimbi ziqinisekisa ukuthengwa kwezinto ezithembekileyo nezizinzileyo. Yonke ibhetshi yemathiriyeli ekrwada engenayo ivavanywa ngokungqongqo ukuqinisekisa ukuba ukwakheka kwemathiriyeli kuhlangabezana ngokupheleleyo neenkcukacha. Ibhetshi nganye yemveliso ihlolwa okokugqibela phambi kokuba ithunyelwe. Iqela lethu labarhwebi behlabathi elikumgangatho ophezulu linikezela ngobuchule kwiimveliso kunye neenkonzo, izisombululo zokulungisa kunye neengcebiso kwiimfuno zakho. Sinikezela ngomkhondo wokuphela ukuya esiphelweni ukusuka ekubekweni kweodolo ukuya ekuhanjisweni, ukuxhaswa ngoqinisekiso lomgangatho kunye nenkxaso yokuthengisa emva kokuthengisa.
