Umbhobho wentsimbi ojikelezayo ngumbhobho wentsimbi yomthungo owenziwe ngomtya wentsimbi njengemathiriyeli ekrwada, ukhutshiwe kubushushu obuqhelekileyo, kwaye udityaniswe yinkqubo yokuwelda iarc ezenzekelayo enamacala amabini.Umbhobho wentsimbi ojikelezayo uthumela intsimbi yomcu kwiyunithi yombhobho odityanisiweyo, kwaye emva kokuqengqeleka ngeerola ezininzi, intsimbi yomcu iyasongwa ngokuthe ngcembe ukuze yenze ibhilethi yetyhubhu ejikelezayo enesithuba sokuvula.Lungisa ukucuthwa kwerola ye-extrusion ukulawula isithuba se-weld seam kwi-1 ~ 3mm, kwaye wenze iziphelo zombini ze-welding port zigungxule.
Inkqubo yeMveliso
(1) Imathiriyeli ekrwada zizikhoyili zentsimbi, iingcingo zokuwelda, kunye ne-fluxes.Ngaphambi kokuba zisetyenziswe, kufuneka zidlule kuvavanyo olungqongqo lomzimba kunye neekhemikhali.
(2) I-head-to-tail butt joint ye-strip yentsimbi ithatha i-arc-wire okanye i-double-wire submerged arc welding, kunye ne-arc welding ezenzekelayo ephantsi kwamanzi isetyenziselwa ukulungiswa kwe-welding emva kokuqengqeleka kwimibhobho yentsimbi.
(3) Ngaphambi kokuqulunqwa, intsimbi ye-strip ihlanjululwa, inqunywe, icwangciswe, icociwe, ihanjiswe kwaye igobe ngaphambili.
(4) Iigeyiji zoxinzelelo lombane zisetyenziselwa ukulawula uxinzelelo lweesilinda kumacala omabini omqhubi ukuqinisekisa ukuhanjiswa okugudileyo komcu.
(5) Ukwamkela ulawulo lwangaphandle okanye ukwenziwa koluhlu lolawulo lwangaphakathi.
(6) Isixhobo sokulawula i-weld gap sisetyenziselwa ukuqinisekisa ukuba i-gap ye-weld ihlangabezana neemfuno ze-welding, kunye nobubanzi bombhobho, ukungahambi kakuhle kunye ne-weld gap ilawulwa ngokungqongqo.
(7) Zombini i-welding yangaphakathi kunye ne-welding yangaphandle zisebenzisa i-American Lincoln welding machine kwi-welding-wire okanye i-double-wire submerged arc welding, ukuze kufumaneke umgangatho ozinzileyo we-welding.
(8) I-welded seams zonke zihlolwe yi-intanethi eqhubekayo ye-ultrasonic i-flaw detector, eqinisekisa i-100% yovavanyo olungonakalisi ukugubungela i-spiral welds.Ukuba kukho isiphene, kuya ngokuzenzekelayo i-alamu kwaye itshize uphawu, kwaye abasebenzi bemveliso banokuhlengahlengisa iiparitha zenkqubo nangaliphi na ixesha ngokutsho oku ukuphelisa isiphene ngexesha.
(9) Sebenzisa umatshini wokusika iplasma yomoya ukusika umbhobho wentsimbi ube ngamaqhekeza omnye.
10 inkqubo yokwenza umbhobho ifanelekile Emva koko, inokufakwa ngokusemthethweni kwimveliso.
(11) Amalungu aphawulwe ngokufunyaniswa kwempazamo ye-ultrasonic kwi-weld iya kuphinda ihlolwe i-ultrasonic manual kunye ne-X-ray.Ukuba ngokwenene kukho iziphene, emva kokulungiswa, ziya kuphinda zihlolwe ngokungenakonakala kuze kube yilapho iziphene ziqinisekiswa ukuba zipheliswe.
(12) Imibhobho apho intsimbi yentsimbi idibanisa iimpundu kunye neejoyinti ze-D ezinqumlana ne-spiral welds zikhoyo zonke ziye zahlolwa nge-X-reyi ye-TV okanye ifilimu.
(13) Umbhobho ngamnye wensimbi uphumelele uvavanyo loxinzelelo lwe-hydrostatic, kwaye uxinzelelo luvalwe nge-radially.Uxinzelelo lovavanyo kunye nexesha zilawulwa ngokungqongqo ngumbhobho wentsimbi uxinzelelo lwamanzi isixhobo sokubona microcomputer.Iiparamitha zovavanyo ziprintwa ngokuzenzekelayo kwaye zirekhodwe.
(14) Isiphelo sombhobho senziwe ngoomatshini bokulawula ngokuchanekileyo ukuqina kobuso besiphelo, i-angle ye-bevel kunye ne-edge ebomvu.
Unyango lwe-weld
1. Ukuba i-gap ikhulu kakhulu, umphumo wokusondela uya kuncitshiswa, ukushisa kwe-eddy current kuya kuba nganelanga, kwaye i-intergranular bonding ye-weld iya kuba yimbi, okubangela ukungabikho kokudibanisa okanye ukuqhekeka.
2. Ukuba i-gap incinci kakhulu, umphumo wokusondela uya kwanda, ukushisa kwe-welding kuya kuba kukhulu kakhulu, kwaye i-weld seam iya kutshiswa;okanye i-weld seam iya kwenza imingxuma enzulu emva kokukhupha kunye nokuqengqeleka, okuya kuchaphazela umgangatho womphezulu we-weld seam.
Emva kokuba imiphetho emibini ye-tube engenanto ishushu kwiqondo lokushisa lokutshisa, phantsi kwe-extrusion ye-roller extrusion, iinkozo eziqhelekileyo zetsimbi zenziwe ukuba zingene kwaye zidibanise, kwaye ekugqibeleni zenze i-weld eqinile.Ukuba i-extrusion force ye-spiral steel pipe incinci kakhulu, inani leekristale eziqhelekileyo ezenziweyo liya kuba lincinci, amandla e-weld metal aya kuncipha, kwaye kuya kwenzeka ukuqhekeka emva koxinzelelo;ukuba i-extrusion force inkulu kakhulu, isinyithi esinyibilikisiweyo siya kucudiswa ngaphandle kwe-weld, ayinciphisi nje amandla e-weld seam, kodwa ivelisa inani elikhulu le-burrs yangaphakathi nangaphandle, kwaye ibangela iziphene ezifana ne-weld laps. .
Iimpawu zenkqubo
Iimpawu eziphambili zenkqubo yombhobho wentsimbi ejikelezayo:
a.Ngethuba lenkqubo yokwenza, i-deformation ye-steel plate ifana, uxinzelelo oluseleyo luncinci, kwaye umphezulu awuvelisi imikrwelo.Umbhobho wentsimbi ejiyileyo owenziweyo unokuguquguquka okukhulu kubungakanani kunye noluhlu oluchaziweyo lobubanzi kunye nobukhulu bodonga, ngakumbi kwimveliso yemibhobho enodonga olungqingqwa yodidi oluphezulu, ngakumbi imibhobho emincinci enodonga olungqingqwa.Kukho iimfuno ezingaphezulu ngokubhekiselele kwiinkcukacha zemibhobho yentsimbi ye-spiral.
b.Ukusebenzisa itekhnoloji ye-arc ye-arc enecala eliphindwe kabini, i-welding inokuqondwa kwindawo efanelekileyo, kwaye akukho lula ukuba neziphene ezifana nokungahambi kakuhle, ukuphambuka kwe-welding kunye nokungena okungaphelelanga, kwaye kulula ukulawula umgangatho we-welding.
c.Ukuqhuba ukuhlolwa komgangatho we-100% wemibhobho yensimbi, ukwenzela ukuba yonke inkqubo yokuvelisa ipayipi yensimbi iphantsi kokuhlolwa okusebenzayo kunye nokubeka iliso, ngokufanelekileyo ukuqinisekisa umgangatho wemveliso.
d.Zonke izixhobo zomgca wemveliso yonke inomsebenzi wokunxibelelana kunye nenkqubo yokufumana idatha yekhompyutheni ukuze ifezekise ukuhanjiswa kwedatha yexesha langempela, kwaye iiparitha zobugcisa kwinkqubo yokuvelisa zihlolwe yigumbi lokulawula eliphakathi.
