Imibhobho yensimbi ye-galvanized yinto esetyenziswa ngokuqhelekileyo kubomi banamhlanje, kwaye i-welding yindlela yokudibanisa esetyenziswa ngokuqhelekileyo. Umgangatho we-welding uhambelana ngokuthe ngqo nokhuseleko kunye nokuzinza kwemveliso. Ngoko ke zeziphi iingxaki esifanele sinikele ingqalelo kuzo ukuze siqinisekise umgangatho weemveliso ezidityanisiweyo?

1. Ubukhulu bombhobho wensimbi Ekuveliseni nasekusetyenzisweni kwemibhobho yensimbi edibeneyo, ubukhulu bombhobho wensimbi yiparameter ebaluleke kakhulu. Nangona kunjalo, ngenxa yezizathu zokuvelisa kunye nokucubungula, ubukhulu bombhobho wensimbi bunokuba nokuphambuka okuthile. Le migangatho ichaza iiparameters ezifana nobukhulu, ubukhulu, ubunzima, kunye nokunyamezela kwemibhobho yensimbi edibeneyo ukuqinisekisa umgangatho kunye nokhuseleko lwemibhobho yensimbi. Ukuphambuka kobunzima bemibhobho yensimbi edibeneyo kunokuchaphazela umgangatho kunye nokhuseleko lwemibhobho yensimbi. Ukuba ukuphambuka kobunzima bombhobho wensimbi kukhulu kakhulu, kunokubangela ukuba umthamo wokuthwala umbhobho wensimbi uyancipha, ngaloo ndlela uchaphazela ukhuseleko kunye nokuzinza kwemveliso. Ukulawula ukuphambuka kobunzima bemibhobho yentsimbi edityanisiweyo, imigangatho yamazwe ngamazwe ngokuqhelekileyo ichaza imigangatho yokuphambuka okuvumelekileyo kobunzima beepayipi zensimbi ezidibeneyo. Kwimveliso yangempela kunye nokusetyenziswa, kuyimfuneko ukulawula ngokungqongqo kunye nokulawula ngokwemigangatho yokuqinisekisa umgangatho kunye nokhuseleko lwemibhobho yensimbi.

Silawula ngokungqongqo ubuninzi beepayipi zensimbi. Kwimibhobho yensimbi yenkcazo efanayo, ukunyamezela kobunzima ± 5%. Silawula ngokungqongqo umgangatho wombhobho wentsimbi nganye. Senza uvavanyo lobunzima kwibhetshi nganye yeepayipi zetsimbi ukukhusela iimveliso ezingafanelekanga ukuba zingene kwiimarike, zikhusele amalungelo kunye nomdla wabathengi, kwaye siqinisekise ukhuseleko kunye nokuthembeka kwepayipi nganye yensimbi.

2. Ngethuba lenkqubo ye-welding yeepayipi zetsimbi, enye into ebalulekileyo yonyango yomlomo wombhobho wepayipi yensimbi. Ingaba ifanelekile kwi-welding ichaphazela kakhulu umgangatho wemveliso egqityiweyo emva kwe-welding. Okokuqala, kuyimfuneko ukugcina umlomo wombhobho ungenawo umhlwa odadayo, ukungcola, kunye negrisi. Le nkunkuma ichaphazela kakhulu umgangatho we-welding, oya kubangela ukuba i-weld ingalingani kwaye iphulwe ngexesha le-welding, kwaye ichaphazela yonke imveliso ye-welding. I-flatness ye-cross-section yinto ebalulekileyo ekufuneka yenziwe phambi kwe-welding. Ukuba i-cross-section iyancipha kakhulu, iya kubangela ukuba ipayipi yensimbi igobe kwaye ibonakale kwi-angle, echaphazela ukusetyenziswa. Xa i-welding, i-burrs, kunye ne-attachments kwi-fracture yombhobho wensimbi kufuneka ihlolwe kwakhona, ngaphandle koko ayiyi kufakwa. I-burrs kumbhobho wensimbi iya kukrwempa abasebenzi kwaye yonakalise iimpahla zabo xa zilungiswa, nto leyo echaphazela kakhulu ukhuseleko.

Ukuthathela ingqalelo iingxaki ze-welding zabasebenzisi, songeze inkqubo yokucoca umlomo wombhobho kwinkqubo yokuqinisekisa ukuba ujongano lomlomo wombhobho lugudile, luthe tyaba, kwaye alunaburr. Xa usebenzisa i-welding yentsimbi yombhobho, akukho mfuneko yokuphinda usike umlomo wombhobho, olungele abasebenzisi ukuba badibanise ekusebenziseni imihla ngemihla. Ukuphunyezwa kwale nkqubo akunakunciphisa kuphela inkunkuma yezinto ezilahlwayo ekwakufuneka sizibone kwi-welding ngaphambili, kodwa nokwandisa ukusebenza kakuhle kwemveliso, ukunciphisa i-welding deformation, kunye nokuphucula ngakumbi umgangatho weemveliso ze-welding.

3. I-Weld I-weld yombhobho wensimbi ibhekisela kwi-weld eyenziwe ngumbhobho wensimbi ngexesha lenkqubo ye-welding. Umgangatho we-weld yensimbi yombhobho uchaphazela ngokuthe ngqo ukusebenza kunye nokhuseleko lombhobho wensimbi. Ukuba kukho iziphene kwi-weld yentsimbi yombhobho, njenge-pores, i-slag inclusions, i-cracks, njl., iya kuchaphazela amandla kunye nokutywinwa kombhobho wensimbi, okubangelwa ukuvuza kunye nokuphuka kombhobho wensimbi ngexesha lenkqubo ye-welding, ngaloo ndlela ichaphazela. umgangatho kunye nokhuseleko lwemveliso.

Ukuqinisekisa umgangatho we-welds, songeze izixhobo zokubona i-turbine weld kumgca wokuvelisa ukufumanisa isimo se-weld yombhobho wentsimbi nganye. Ukuba kukho ingxaki ye-weld ngexesha lenkqubo yokuvelisa, i-alamu iya kuvakala ngokukhawuleza ukukhusela iimveliso ezinengxaki ekufakweni kwiphakheji yemveliso egqityiweyo. Siqhuba uvavanyo olungonakalisi, uhlalutyo lwe-metallographic, uvavanyo lwepropathi yomatshini, njl.njl kwibhetshi nganye yemibhobho yentsimbi eshiya umzi-mveliso ukuqinisekisa ukuba abathengi abasezantsi abadibananga neengxaki ezifana nokusebenza kwemveliso engazinzanga kunye nenkqubela phambili ye-welding ecothayo ngenxa yeengxaki zemibhobho yentsimbi ngexesha lokucubungula. imisebenzi.
