Mbini. Iinkcukacha zenkqubo yokuvelisa ubukhulu obukhulu lsaw umbhobho wentsimbi
1. Sebenza ngaphambi kokuba wenze
Imathiriyeli ekrwada ziikhoyili zentsimbi, iingcingo zokuwelding, kunye ne-flux. Kufuneka udlule kuvavanyo oluqatha lomzimba kunye neekhemikhali phambi kokuba utyale imali. Amalungu e-butt eentsimbi zentsimbi adityaniswe nge-monofilament okanye i-arc welding yocingo oluphindwe kabini. Emva kokuba ityhubhu yentsimbi iqengqeleke, i-arc ye-arc isetyenziselwa ukuwelda ngokuzenzekelayo.

2. Inkqubo yokubumba
I-gauge yokudibanisa yombane isetyenziselwa ukulawula ukunyanzeliswa kweesilinda zokuxinzelela kumacala omabini omqhubi ukuqinisekisa ukuhanjiswa kakuhle komgca. Umatshini ophambili ubekwe embindini. Ngoko ke, ukulungiswa kwe-roller ethe nkqo (ingakumbi ngaphambi nangemva kwentloko) kufuneka kuhlolwe rhoqo ukuze kuqinisekiswe ukuhanjiswa okungqongqo komda. Baleka kwindlela echazwe yinkqubo kwaye ugqithise indawo eyilelwe i-meshing point. Ukulawulwa kwangaphandle okanye ukuqulunqwa komqulu wolawulo lwangaphakathi kusetyenziselwa ukujonga ukuba i-perimeter, i-ellipticity, i-straightness, njl. Ukuba ayihambelani neemfuno, iya kuqhubeka ihlengahlengiswa de ihlangabezane neemfuno.

3. Inkqubo ye-Welding
Isixhobo sokulawula i-weld gap sisetyenziselwa ukuqinisekisa ukuba i-gap ye-weld iyanelisa iimfuno ze-welding. Ubungakanani bombhobho, ubungakanani bokungalungelelanisi, kunye nesithuba se-weld zonke zilawulwa ngokungqongqo. Umgangatho we-seam yokwenza kufuneka uqwalaselwe ngokuqhubekayo, kwaye kufuneka kufunyanwe ukuba imida engafanelekanga, i-seams evulekileyo, njl njl. Ukulungelelanisa i-angle ye-axle yangasemva ngexesha lokuqinisekisa umgangatho wokwenza; xa imeko ingaqhelekanga, khangela ukuba ububanzi bokusebenza komtya, imeko yangaphambili yokugoba komphetho, indawo yokuhambisa umgca, i-angle ye-roller encinci, njl., itshintshile, kwaye uthathe amanyathelo okulungisa ngexesha. Abavelisi bemibhobho yentsimbi yomthungo kaHebei okwangoku basebenzisa umatshini wokuwelda wase-United States weLincoln wocingo olunye okanye ngocingo oluphindwe kabini oluntywiliselwe i-arc welding ukuze bafumane umgangatho ozinzileyo wokuwelda. Abavelisi bemibhobho yentsimbi yomthungo othe tye baya kuthi gqolo bajonge umgangatho wokwenza amajoyina, kwaye baya kulungisa ngokukhawuleza i-angle ye-axle yangasemva ukuqinisekisa umgangatho wokubumba kwimeko ye-edges engalungiswanga kakuhle, i-seams evulekile, njl. ukuba iimeko aziqhelekanga, khangela ububanzi bokusebenza, i-edge pre-bending condition, kunye nokuhanjiswa kwentsimbi yentsimbi. Ingaba kukho nayiphi na inguqu kwisikhundla somgca, i-angle ye-roller encinci, njl., kwaye uthathe amanyathelo okulungisa ngexesha.

4. Ukufunyanwa
Iiwelds ezidityanisiweyo zonke zahlolwa kwi-intanethi nge-automatic ultrasonic flaw detector ukuze kuqinisekiswe i-100% yokuhlolwa okungonakalisi kokuhlolwa kwe-spiral weld. Ukuba kukho iziphene, ziya kuphazamiseka ngokuzenzekelayo kwaye zipeyintwe. Abasebenzi bemveliso baya kulungelelanisa iiparameters zenkqubo nanini na ukuphelisa iziphene ngexesha. Xa i-diameter ye-nominal D ≥ 426mm, iziphene zangaphakathi zombhobho wensimbi kufuneka zicocwe kwaye zilungiswe ngaphakathi; xa i-D ≤ 426mm, iziphene zangaphakathi zingasuswa ngaphandle ukuze zenze i-welding yangaphandle. Emva kokulungiswa kwe-welding, i-weld kufuneka ibe phantsi kwaye ubuninzi bodonga obuseleyo emva kokusila kufuneka bube phakathi kokunyamezela kodonga oluchaziweyo. Ngaphambi kokulungisa umbhobho wensimbi odibeneyo kwinkqubo elandelayo, kuyimfuneko ukuhlola ngokucophelela ukuba kukho nayiphi na impazamo elahlekileyo okanye elahlekileyo kumbhobho wensimbi kwaye uyilungise ngaphambi kokuba uqhubekele kwinkqubo elandelayo. Amalungu e-butt-welded joints of steel butt-welded joints kunye ne-spiral welds zonke zihlolwe ngumabonwakude we-X-ray okanye ifilimu. Umbhobho ngamnye wavavanywa nge-hydrostatic kwaye uxinzelelo lwavalwa nge-radial. Uxinzelelo lovavanyo kunye nexesha lilawulwa ngokungqongqo ngumbhobho wensimbi we-hydraulic pressure testing device. Iiparamitha zovavanyo ziprintwa ngokuzenzekelayo kwaye zirekhodwe.

5. Ukupakishwa ngaphandle kwethala leencwadi
Umbhobho ekupheleni machining, ukuze isiphelo ubuso perpendicularity, engile groove kunye edge blunt zilawulwa ngokuchanekileyo. Umsiki weplasma womoya usika ityhubhu yentsimbi ibe ngamaqhekeza ngamanye. Emva kokuba i-blade ibuthuntu okanye yonakele, i-blade entsha kufuneka itshintshwe ngokukhawuleza. Incakuba entsha mayilolwe ngelitye ngaphambi kokuba isetyenziswe, yaye mayingacolwa ngesisi. Emva kokuba i-blade iphukile, ingasetyenziselwa emva kokufaka ilitye lokugaya kwakhona emva kokugaya nge-grinder.
