Nws yog qhov nyuaj heev kom ua tiav cov qauv siab tshaj plaws ntawm kev ua tau zoo thiab kev nyab xeeb siv phau ntawv vuam. Qhov no yog vim qee txoj haujlwm vuam, nyiaj siv ua haujlwm thiab down-hand welds piv txwv li, feem ntau ua rau faulty welds vim txwv kev nkag mus rau tus neeg siv muaj nyob rau hauv cov vuam txoj haujlwm. Txhawm rau kom muaj kev tswj xyuas tiav ntawm lub pas dej ua ke, qhov sib npaug zoo meej yuav tsum tau tswj xyuas ntawm lub zog gravitational thiab qhov nro ntawm txhua txoj haujlwm ntawm lub teeb. Los ntawm kev siv cov tshuab sib txawv ntawm cov txheej txheem, qee qhov ntawm cov txheej txheem vuam yog ua los ntawm cov khoom siv tshuab. Nco ntsoov tias tus welder yuav ib txwm saib xyuas thiab tswj cov txheej txheem. Hauv qhov xwm txheej zoo tagnrho, txhua qhov kev ntsuas vuam yuav tsum tau ua tiav ua ntej vuam pib. Hauv kev xyaum, txawm li cas los xij, qhov muaj qhov sib txawv ntawm qhov tsis sib xws txhais tau hais tias nws yog qhov tsim nyog rau cov welder los ua kev kho kom raug.
Orbital Welding ntawm Tubing siv tag nrho cov vuam taub hau yog txheej txheem fusion raws li ASME Tshooj 9. Tsis muaj cov hlau muab tub lim ntxiv.
Ib qho kev vam meej tsis siv neeg orbital GTA weld yog 100% rov ua tau ntev npaum li tus neeg teb xov tooj saib xyuas qhov sib txawv thiab ua cov qauv raws sij hawm lossis daim coupon uas tau tshuaj xyuas kom tiav kev nkag mus. Pom tias qhov sib txawv tau hloov pauv yog qhov kev txawj ntse thiab tuaj yeem plam tau yooj yim. Kev cob qhia thiab kev paub dhau los yuav tsum muaj rau tus neeg teb xov tooj kom ua tiav ntawm kev tsim cov vuam siv tau zoo.
ASME yuav tsum tau ntawv pov thawj ntawm ib tug neeg raws li ib tug orbital welding tus neeg teb xov tooj yuav tsum tau tus neeg yuav tsum tau teem lub vuam taub hau thiab programmed lub vuam tshuab thiab tsim 6 cov qauv sib law liag uas yuav dhau kev khoov thiab / los yog tensile xeem. Kev cob qhia kws tshaj lij feem ntau tau txais rau ib tus neeg tuaj yeem ua cov qauv uas dhau qhov kev xeem.
Qhov kev vam meej tsis siv neeg orbital GTA weld yog nyob ntawm kev ua kom zoo ntawm ntau qhov sib txawv tseem ceeb uas koom nrog kev ua haujlwm ntawm lub tshuab vuam thiab teeb tsa ntawm "weld head".
Kev saib xyuas ntawm lub taub hau weld feem ntau dhau los ua qhov tseem ceeb hauv kev rov ua tiav ntawm kev vam meej welds. Weld taub hau sab hauv tuaj yeem dhau los ntawm kev siv tsis raug. Lub charring yog cov pa roj carbon deposits uas muaj peev xwm ua hluav taws xob thiab luv luv Circuit Court ntws ntawm cov tungsten. Weld taub hau muaj cov txheej txheem ntawm precision planetary iav uas tuaj yeem hnav dhau sijhawm. Yuav tsum tau tu thiab tu kom zoo.
Kev vam meej orbital welding kuj yog nyob ntawm kev siv cov khoom siv tubing zoo. Feem ntau tsuas yog 316L stainless hlau tubing (tsis yog yeeb nkab) thiab fittings yog siv rau qhov tsis siv neeg orbital GTA vuam thiab tau txais los ntawm ntau lub tuam txhab tshwj xeeb.
Kev vam meej orbital welding kuj yog nyob ntawm qhov muaj peev xwm huv si ntawm Argon rau thaub qab thiab tiv thaiv roj. Qhov tsawg kawg nkaus purity yuav yog 99.995% rau cov kev siv niaj hnub. Rau qee qhov kev siv nws yog ib qho tsim nyog yuav tsum tau siv ultra siab purity argon, 99.9998% purity thiab cov ntawv thov no yuav tsum tau siv tag nrho cov khoom siv purity siab (valve, regulators thiab flow control). Feem ntau, tsis muaj cov khoom siv roj hmab tuaj yeem siv los ntxuav cov khoom siv roj av vim cov roj hmab absorbs thiab tso cov dej noo thiab oxygen rau hauv cov kwj deg argon. Cov dej noo thiab cov pa oxygen (hauv Argon) yog cov kab mob uas ua rau muaj kev vam meej tsis siv neeg orbital weld.
Weld daim coupons, tej daim hlau siv los kuaj ib tug welder txuj ci, [3] feem ntau yog npaj rau thaum pib ntawm ib tug vuam hloov, txhua lub sij hawm tej yam txawv txawv yog hloov los yog hloov thiab thaum kawg ntawm kev ua haujlwm (thiab ntau zaus raws li qhov yuav tsum tau ua los ntawm ib tug inspector). Txhua daim coupon yuav tsum raug tshuaj xyuas sab hauv thiab sab nraud kom paub tseeb tias kev nkag mus tag nrho, cov hlaws dav dav thiab lwm yam. Nrog me me diameters nws yog feem ntau yuav tsum tau qhib lub daim coupon no mus xyuas cov weld hlaws. Txhua daim coupon yuav tsum nthuav tawm ua tiav kev nkag mus thiab zoo ib yam hlaws dav. Kev hloov pauv hauv qhov sib xws yog qhov qhia txog qhov teeb meem uas yuav tsum tau daws ua ntej txuas ntxiv mus.
Orbital welding feem ntau tsuas yog ua rau TUBING thiab tsis yog yeeb nkab rau ntau qhov laj thawj tseem ceeb tshaj plaws yog tias cov tubing yields zoo ib yam sab nraud diameters uas yog qhov tseem ceeb kom haum rau hauv lub taub hau vuam.
Tsis siv neeg Orbital GTA welding tau dhau los ua tus qauv kev koom ua ke rau kev ua haujlwm siab ntawm cov pa roj thiab cov kua siv hauv SEMICONDUCTOR thiab Pharmaceutical manufacturing industries. Cov tshuab no raug ntsuas rau qhov siab tshaj plaws purity thiab xau nruj kev ncaj ncees. Tag nrho cov kev lag luam tshwj xeeb xa khoom li qub, fittings, regulators, gauges thiab lwm yam khoom siv rau orbital vuam thiab siv nyob rau hauv siab purity daim ntaub ntawv tau tsim txij li thaum nruab nrab xyoo 1980s. Rau raj vuam nyob rau hauv siab purity daim ntaub ntawv tsuas yog ib tug tag nrho lub taub hau weld yuav siv tau.
