Thaum tus kws tsim khoom siv tes ua yuav tsum tsim ib qho kev sib txuas ntawm ntau yam khoom ua los ntawm cov hlau, titanium, stainless hlau lossis lwm yam khoom siv, nws yuav tsum siv argon vuam, uas txawv ntawm txhua qhov sib txawv hauv nws qhov tshwj xeeb. Chav tsev ua ke tag nrho cov yam ntxwv ntawm ib qho hluav taws xob arc thiab cov khoom siv roj. Txhawm rau kom ua haujlwm sai thiab ua tau zoo, koj yuav tsum npaj cov pas nrig rau argon arc vuam ua ntej.
Txoj Cai Ua Haujlwm
Zoo melting ntawm cov npoo ntawm ntau qhov chaw yuav tsum tau koom nrog thiab muab tub lim cov ntaub ntawv, uas ib tug me me weld yog tsim, yog tiav vim kub kub uas tshwm sim los ntawm qhov kub ntawm ib tug hluav taws xob arc. Argon muab kev tiv thaiv kev ua haujlwm. Ua tib zoo vuam ntawm cov hlau tsis-ferrous thiab alloys, nrog rau cov hlau alloy, nws muaj nws tus yam ntxwv. Thaum muaj kev cuam tshuam nrog oxygen thiab lwm yam khoom muaj nyob rau hauv ib puag ncig, active oxidation ntawm hlau tshwm sim. Qhov no yogQhov xwm txheej tsis zoo cuam tshuam txog qhov kawg ntawm qhov zoo ntawm cov seam tsim, uas hloov tawm kom xoob. Txhawm rau zam tag nrho cov ntsiab lus tsis zoo, cov kws tshaj lij pom zoo kom siv cov pas nrig rau TIG vuam.
yam ntxwv
Vuam pas nrig yog nthuav tawm hauv daim ntawv ntawm cov pa hlau hlau lossis cov khoom siv polymer, uas yog siv los ntawm cov kws tshaj lij los sau thiab tsim cov seam muaj zog. Qhov ntev ntawm cov khoom txheem yog ib meter. Rau kev ua haujlwm zoo, cov rods raug mob rau hauv reels. Cov khoom yog qhov zoo tagnrho rau kev kho txhua hom hlau. Classic muab tub lim rau argon arc vuam yuav tsum phim cov khoom siv hauv paus uas ua haujlwm. Tab sis cov khoom siv no tsis haum rau stainless hlau.
Txoj Cai Ua Haujlwm
TIG welding rods siv tsis tau yam tsis muaj lub teeb. Ib qho tshwj xeeb tungsten electrode nrog qhov projection ntawm 5 hli yog muab tso rau hauv nruab nrab ntawm chav tsev no. Nyob rau hauv lub puab compartment, cov khoom yog tsau nrog ib tug tuav. Rau lub sij hawm muab kev tiv thaiv roj, lub burner yog nruab nrog ib tug txhim khu kev qha ceramic nozzle. Lub seam yog tsim nrog ib tug hlau. Rau kev ua haujlwm ntawm cov hlau tsis huv, cov pas nrig muab tub lim rau argon arc vuam yog xaiv tshwj xeeb tshaj yog lub luag haujlwm kom cov txiaj ntsig ua tau raws li txhua yam kev ua haujlwm. Thaum ua haujlwm, ib qho hluav taws xob arc yog ignited. Cov electrode yuav tsum tsis txhob kov qhov chaw yuav tsum tau koom nrog. Txoj cai no yogyuav tsum tau hwm raws li lub peev xwm ionization ntawm argon yog siab heev.
Ntau yam
Hnub no tsis muaj ib qho kev faib tawm ntawm cov welding rods, vim muaj ob peb ntawm lawv. Qhov kev xaiv zaum kawg yog nyob ntawm hom khoom siv ua tiav. Aluminium filler rods rau TIG vuam yog tus cwj pwm los ntawm kev ua haujlwm siab. Lub resulting seams yeej tsis tawg. Aluminium bars muaj cov thermal conductivity siab, uas muaj nuj nqis heev hauv kev lag luam loj. Cov khoom siv tooj liab yog nyob rau hauv qhov kev thov loj tshaj plaws. Ntau tus yam ntxwv zoo tso cai rau kev ua haujlwm zoo ntawm tooj liab, tsis hais qhov loj ntawm qhov.
