Thaum Tig Vuam yog ua yam tsis muaj kev sib txawv ua cov tub lim cov tub lim, cov txheej txheem yog tus tsim "autivenous raug vuam" (qee zaum hu ua "kev sib cav sib ceg). Cov txheej txheem no tsuas yog tso siab rau melting ntawm lub hauv paus hlau los ua tus weld, tshem tawm cov kev xav tau rau cov xaim hlau txuas ntxiv. Autogenous Tig Vuam yog muaj nuj nqis rau nws cov txiaj ntsig thiab cov txiaj ntsig kom huv tau, txawm hais tias muaj qhov muaj peev xwm ua tau los ua cov khoom siv hauv qab, puas tuaj yeem ua kom muaj zog, puas tuaj yeem ua txhaum.
Autogenous Tig Vuam ua haujlwm los ntawm kev tsom mus rau ntawm ob daim hlau, cua sov lawv rau lawv cov moltten txhim kho ua ke. Qhov tseem ceeb ntawm no yog tias Weld yog tsim tag nrho ntawm lub hauv paus hlau {1} Tsis muaj chaw muab tso rau choj rau choj lossis tsim tsa Weld hlaws. Qhov no yuav tsum tau kaw kom haum rau -} yuav tsum tau ua raws li cov neeg ua haujlwm tsawg dua (feem ntau tsawg dua lossis sib npaug Txawm tias cov khoob me me tuaj yeem ua rau underfilling, porosity, lossis tsis muaj fusion, raws li tsis muaj tus muab rau kev them nyiaj rau kev ua haujlwm.
Cov txheej txheem sib zog thauj vuam siv qhov xam pom qhov yooj yim Cov roj inert tiv thaiv cov molten pas dej paug (oxidation, tsis muaj tub lim rau hauv auturities, tej yam kev paug yuav ncaj ncaj qha weld. Qhov no ua rau autrogenous tig zoo tshaj plaws rau cov hlau nkag siab tsis zoo, suav nrog cov hlau tsis muaj zog, xws li khaws cia corrosion, uas yog qhov tseem ceeb yog qhov tseem ceeb.
Autogenous Tig Vuam yog zoo tshwj xeeb yog zoo {{0}-} Cov ntaub ntawv siv tau yooj yim (feem ntau 0.25 nti tuab). Hauv cov ntawv thov no, ntxiv cov tub lim tuaj yeem pheej hmoo overbuilding lub weld, tsim cov khoom siv ntau uas yuav ua rau cov hlau uas tsis muaj qhov sib luag lossis cuam tshuam qhov txawv txav. Cov piv txwv suav nrog Vuam Sheet Hlau Cheebtsam hauv Aerospace (piv txwv li, tooj, tooj liab bus tunks thiab tsawg heev distortion yog qhov tseem ceeb.
Nws tseem siv tau rau leeg vuam -}}}}}}}} weld (piv txwv li kev tso tsheb hlau luam lossis kev tso tsheb hlau luam los ntawm cov nplooj ntawv tiaj). Lub autogenous txoj hauv kev kom zoo, tsis muaj cov tub rog uas tsis muaj zog thaum muaj cov khoom siv tau siab los yog cov kua dej uas muaj zog.
Txawm li cas los xij, autrogenous tig vuam muaj kev txwv. Nws tsis haum rau cov ntaub ntawv tuab (saum 0.125 nti) vim tias cov khoom siv hauv paus ib leeg tsis tuaj yeem muab cov khoom siv molten txaus los ntawm cov tuab weld kom muaj zog. Cov ntu tuab yuav tsum muaj cov tub lim kom ua kom tiav kev nkag mus thiab zam kom tawg. Ib qho ntxiv, nws xav tau kev kawm tshwj xeeb los ntawm tus tswv cuab: Kev tswj hwm qhov tseeb, thiab kev tawm suab sov, thiab cua sov yog qhov kev kub hnyiab los ntawm cov hlau lossis tawm tsis tiav fusion. Txawm muaj kev sib txawv me me hauv cov cua sov tuaj yeem ua rau muaj kev tiv thaiv weld rau "sag" lossis tsim cov chaw ua haujlwm, raws li tsis muaj tus muab faus rau cov pas dej molten.
Lwm qhov kev txiav txim siab yog lub hauv paus hlau qhov sib txuam. Autogenous vuam ua haujlwm zoo tshaj plaws thaum ob daim tau koom nrog yog tib qho kev sib txuas. Sib tov cov hlau tsis sib xyaw (piv txwv li, cov hlau stainless thiab carbon hlau) tsis muaj cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm kev pheej hmoo ntawm Weld, uas tuaj yeem ua rau tawg. Cov xaim xaim yog feem ntau siv nyob rau hauv cov hlau dissimilar hlau vuam rau choj alloy sib txawv, ua cov txheej txheem autrogenous impactical nyob rau hauv cov xwm txheej zoo li no.
Hauv chaw muaj kev muaj, autrogenous tig vuam yog nquag siv tau siv cov tshuab robotic lossis tshwj xeeb ntawm cov neeg pab txiv. Automation ua kom muaj zog sib xws, taug kev nrawm, thiab sib koom ua ke- dhau los ntawm kev sib tw ntawm txhais tes kev sib tw. Caw rho tawm tus nplaig nyob rau hauv huab hwm coj ntau, xws li kev tsim khoom stainless hlau lossis txhuas kev hloov pauv cua sov, qhov chaw muaj txiaj ntsig zoo dua qub.
Thaum "autrogenous yog vuam" yog lub hom phiaj qhia, nws qee zaum tsis meej pem nrog lwm cov tsis muaj {{0} {cov txheej txheem ua haujlwm. Piv txwv li, kev tawm tsam vuam (piv txwv li, chaw vuam) kuj feses fuster) kuj tseem siv hluav taws xob ua kom muaj hluav taws xob, tsis yog ARC. Autogenous tig tseem txawv rau nws siv ntawm arc thiab inert gas shielding, txawm tias tsis muaj tub lim.
Hauv cov ntsiab lus, Autogenous TIG VUAM Nws txawj ua kom zoo nyob rau hauv nyias - kev siv Welge, yog tias nws yuav tsum tau ua kom ceev faj thiab kev txawj yuav zam tsis txhob muaj qhov tsis xws luag. Rau cov ntaub ntawv tuab, cov pob qij txha, lossis pob qij txha nrog cov khoob, ua kom}}} tab sis autienial tig tseem ceeb, siab} precision fittions.
