Kev tsim cov yeeb nkab steel hnub los ntawm thaum ntxov 1800's. Thaum pib, cov yeeb nkab tau tsim los ntawm tes - los ntawm cua sov, khoov, lapping, thiab rauj cov npoo ua ke. Thawj cov txheej txheem kev tsim cov yeeb nkab tsis siv neeg tau tsim tawm hauv xyoo 1812 hauv tebchaws Askiv. Cov txheej txheem tsim khoom tau txuas ntxiv txhim kho txij li lub sijhawm ntawd. Qee cov txheej txheem tsim yeeb nkab nrov tau piav qhia hauv qab no.
Lap Vuam
Kev siv lap welding los tsim cov yeeb nkab tau qhia nyob rau hauv thaum ntxov 1920's. Txawm hais tias txoj kev no tsis ua haujlwm lawm, qee cov yeeb nkab uas tau tsim los siv cov txheej txheem vuam yog tseem siv niaj hnub no.
Nyob rau hauv txheej txheem vuam, hlau tau rhuab rau hauv lub cub tawg thiab ces dov mus rau hauv cov duab ntawm ib lub tog raj kheej. Cov npoo ntawm cov phaj hlau tau ces "scarfed". Scarfing suav nrog overlaying sab hauv ntawm lub phaj steel, thiab cov ntug tapered ntawm sab nraud ntawm lub phaj. Tom qab ntawd lub seam tau welded siv lub pob vuam, thiab cov yeeb nkab uas muaj cua sov tau dhau los ntawm cov chais uas yuam cov seam ua ke los tsim kev sib raug zoo.
Cov welds tsim los ntawm lap welding tsis zoo li cov uas tsim los ntawm cov txheej txheem niaj hnub. Lub Koom Haum American Society of Mechanical Engineers (ASME) tau tsim ib qho kev sib npaug rau kev suav cov kev ua haujlwm siab ntawm cov yeeb nkab, raws li hom kev tsim khoom. Qhov kev sib npaug no suav nrog qhov sib txawv uas hu ua "kev sib koom ua ke", uas yog raws li hom vuam siv los tsim cov seam ntawm cov yeeb nkab. Seamless kav dej muaj qhov sib koom ua ke ntawm 1.0 Lap welded yeeb nkab muaj qhov sib koom ua ke ntawm 0.6.
Electric Resistance Welded Yeeb Nkab
Hluav taws xob tsis kam welded (ERW) yeeb nkab yog tsim los ntawm txias-tsim ib daim ntawv ntawm cov hlau rau hauv cov duab cylindrical. Tam sim no ces dhau ntawm ob lub npoo ntawm cov hlau kom sov cov hlau mus rau qhov chaw uas cov npoo raug yuam ua ke los ua ib daim ntawv cog lus yam tsis tas siv cov khoom siv welding. Thaum pib, cov txheej txheem tsim khoom no siv cov zaus AC tam sim no los ua kom sov cov npoo. Cov txheej txheem tsawg zaus no tau siv txij li xyoo 1920 txog rau xyoo 1970. Xyoo 1970, cov txheej txheem tsawg zaus tau hloov pauv los ntawm cov txheej txheem ERW zaus uas ua rau cov khoom siv zoo dua qub.
Sij hawm dhau mus, cov welds ntawm tsawg zaus ERW yeeb nkab tau pom tias muaj kev cuam tshuam rau kev xaiv seam corrosion, nuv kab nrib pleb, thiab kev sib txuas ntawm cov seams tsis txaus, yog li tsis tshua muaj ERW tsis siv los tsim cov yeeb nkab. Cov txheej txheem siab zaus tseem yog siv los tsim cov yeeb nkab rau kev siv hauv kev tsim cov kav dej tshiab.
Electric Flash Welded Yeeb Nkab
Hluav taws xob flash welded yeeb nkab tau tsim los pib xyoo 1927. Flash vuam tau ua tiav los ntawm kev tsim cov ntawv hlau rau hauv cov duab cylindrical. Cov npoo tau rhuab kom txog thaum ib nrab molten, ces yuam ua ke kom txog thaum molten hlau raug yuam tawm ntawm kev sib koom tes thiab tsim ib tug hlaws dai. Zoo li tsawg zaus ERW yeeb nkab, cov seams ntawm flash welded yeeb nkab yog raug rau corrosion thiab nuv kab nrib pleb, tab sis rau ib tug tsawg dua li ERW yeeb nkab. Hom yeeb nkab no kuj raug cuam tshuam rau kev ua tsis tiav vim muaj qhov nyuaj ntawm cov phaj hlau. Vim tias feem ntau ntawm cov yeeb nkab flash welded tau tsim los ntawm ib lub chaw tsim khoom, nws ntseeg tau tias cov chaw nyuaj no tshwm sim vim kev sib tsoo ntawm cov hlau thaum lub sijhawm tsim khoom siv los ntawm cov chaw tsim khoom tshwj xeeb. Flash vuam tsis siv los tsim cov yeeb nkab.
Ob chav Submerged Arc Welded (DSAW) yeeb nkab
Zoo ib yam li lwm cov txheej txheem tsim cov yeeb nkab, kev tsim khoom ntawm Ob Chav Submerged Arc Welded Yeeb Nkab koom nrog thawj zaug ua cov hlau phaj rau hauv cov duab cylindrical. Cov npoo ntawm cov dov phaj yog tsim kom V-shaped grooves yog tsim nyob rau sab hauv thiab sab nrauv ntawm qhov chaw ntawm lub seam. Cov yeeb nkab seam yog ces welded los ntawm ib qho dhau ntawm ib qho arc welder ntawm sab hauv thiab sab nrauv (li no ob chav submerged). Lub vuam arc yog submerged nyob rau hauv flux.
Qhov kom zoo dua ntawm cov txheej txheem no yog tias welds nkag mus rau 100% ntawm cov yeeb nkab phab ntsa thiab tsim ib qho kev sib raug zoo ntawm cov khoom siv yeeb nkab.
Seamless Yeeb Nkab
Seamless yeeb nkab tau tsim txij li xyoo 1800's. Thaum cov txheej txheem tau hloov zuj zus lawm, qee cov ntsiab lus tseem nyob li qub. Seamless yeeb nkab yog tsim los ntawm piercing ib tug kub round steel billet nrog ib tug mandrel. Lub hollowed steel yog dua li dov thiab ncab kom ua tiav qhov ntev thiab txoj kab uas hla. Lub ntsiab kom zoo dua ntawm seamless yeeb nkab yog tshem tawm cov seam-cuam tshuam qhov tsis xws luag; Txawm li cas los xij, tus nqi ntawm kev tsim khoom yog ntau dua.
Thaum ntxov seamless yeeb nkab tau raug cuam tshuam los ntawm impurities hauv cov hlau. Raws li cov txheej txheem steel ua tau zoo dua qub, cov teeb meem no tau txo qis, tab sis lawv tsis tau raug tshem tawm tag nrho. Thaum nws zoo li cov yeeb nkab seamless yuav nyiam tsim, seam-welded yeeb nkab, lub peev xwm los txhim kho cov yam ntxwv xav tau hauv cov yeeb nkab yog txwv. Vim li no, seamless yeeb nkab yog tam sim no muaj nyob rau hauv cov qib qis thiab phab ntsa thicknesses welded yeeb nkab.
