Umbhobho wensimbi ojikelezayo wenziwa ngokuqengqeleka kwentsimbi ephantsi-carbon structural okanye ephantsi-alloy structural steel strip kumbhobho, ngokwe-engile ethile yomgca we-spiral (ebizwa ngokuba yi-angle yokubumba), kwaye emva koko ukuwelda i-seams yombhobho.
Ingasetyenziselwa ukuvelisa umbhobho wentsimbi obubanzi obukhulu kunye nentsimbi emxinwa.
Inkcazo yombhobho wentsimbi ejikelezayo ibonakaliswa ngedayamitha yangaphandle * ubukhulu bodonga.
Umbhobho odibeneyo uya kuvavanywa ngovavanyo lwe-hydrostatic, amandla okuqina kunye nokugoba okubandayo, ukusebenza kwe-welding seam kuya kuhlangabezana neemfuno zokucaciswa.
Injongo ephambili:
Umbhobho wensimbi ojikelezayo usetyenziselwa ukuhanjiswa kweoli kunye negesi yendalo.
Inkqubo yokuvelisa:
(1) Izinto ezisetyenziswayo: ikhoyili yentsimbi, ucingo lwewelding kunye ne-flux.Ukuhlolwa okungqongqo ngokomzimba kunye neekhemikhali kuya kwenziwa phambi kokuveliswa.
(2) I-butt ukuwelda intloko kunye nomsila wekhoyili ukwenza iikhoyili ezimbini ezidityanisiweyo, emva koko ithatha ucingo olunye okanye iingcingo eziphindwe kabini ezifakwe kwi-arc welding, kunye ne-arc welding ezenzekelayo ephantsi kwamanzi yamkelwe ukuwelda emva kokuqengqeleka kumbhobho wentsimbi.
(3) Ngaphambi kokwenza, intsimbi yomtya iya kunyuswa, ilungiswe, icwangciswe, icocwe, ithuthwe kwaye igotshwe ngaphambili.
(4) I-gauge yokudibanisa yombane yombane isetyenziselwa ukulawula uxinzelelo lwe-cylinder yeoli ecinezelayo kumacala omabini omqhubi ukuqinisekisa ukuthuthwa kwentsimbi ye-strip kakuhle.
(5) Ukwenza umqulu, sebenzisa ulawulo lwangaphandle okanye ulawulo lwangaphakathi.
(6) Sebenzisa isixhobo solawulo lwe-weld gap ukuqinisekisa ukuba i-gap ye-weld ihlangabezana neemfuno ze-welding, ngoko ububanzi bombhobho, ukungahambi kakuhle kunye ne-weld gap inokulawulwa ngokungqongqo.
(7) Zombini i-welding yangaphakathi kunye ne-welding yangaphandle yamkela umatshini wokuwelda woMbane waseMelika we-American Lincoln wocingo olulodwa okanye iingcingo ezimbini ezintywiliselwe i-arc welding, ukuze ufumane ukusebenza kwe-welding ezinzileyo.
(8) Zonke i-welding seams zihlolwa nge-intanethi eqhubekayo ye-ultrasonic i-flaw detector yokuqinisekisa i-100% yovavanyo lwe-NDT olugubungela zonke i-spiral welding seams.Ukuba kukho iziphene, kuya ngokuzenzekelayo i-alamu kunye namanqaku okutshiza, kwaye abasebenzi bemveliso baya kulungelelanisa iiparitha zenkqubo nanini na ukuphelisa iziphene ngexesha.
(9) Umbhobho wensimbi unqunywe kwisiqwenga esisodwa ngomatshini wokusika.
(10) Emva kokusika kumbhobho wentsimbi enye, ibhetshi nganye yombhobho wentsimbi iya kuxhomekeka kwinkqubo yokuhlola engqongqo yokuqala ukujonga iimpawu zomatshini, ukwakheka kweekhemikhali, imeko yokudibanisa, umgangatho womphezulu wombhobho wentsimbi kunye ne-NDT ukuqinisekisa ukuba inkqubo yokwenza umbhobho. ifanelekile phambi kokuba ifakwe ngokusemthethweni kwimveliso.
(11) Amalungu anamanqaku aqhubekayo okufumanisa i-acoustic flaw kwi-welding seam iya kujongwa kwakhona nge-ultrasonic manual kunye ne-X-reyi.Ukuba kukho iziphene, emva kokulungiswa, umbhobho uya kuba phantsi kwe-NDT kwakhona de kube kuqinisekiswe ukuba iziphene ziphelisiwe.
(12) Umbhobho we-t-joint welding seam kunye ne-T-joint edibanisa i-spiral welding seam iya kuhlolwa ngomabonakude we-X-ray okanye uhlolo lwefilimu.
(13) Umbhobho ngamnye wentsimbi uphantsi kovavanyo lwe-hydrostatic.Uxinzelelo lovavanyo kunye nexesha lilawulwa ngokungqongqo ngesixhobo sokufumanisa ikhompyutha yoxinzelelo lwamanzi lombhobho wensimbi.Iiparamitha zovavanyo ziprintwa ngokuzenzekelayo kwaye zirekhodwe.
(14) Ukuphela kombhobho kumatshini wokulawula ngokuchanekileyo i-perpendicularity, i-angle ye-bevel kunye nobuso beengcambu.
