Phau Ntawv Qhia Tshiab rau Tack Welding Techniques Tshaj Tawm

Tack welding yog cov txheej txheem tseem ceeb hauv ntau cov txheej txheem tsim khoom thiab sib dhos. Tsis tas li ntawd, txoj kev no yog dav siv thoob plaws ntau lub lag luam vim nws cov versatility, stabilizing muaj peev xwm, thiab nqi-zoo.

Yog li ntawd, tsab xov xwm no yuav tshawb txog cov txheej txheem vuam tack, npog nws cov ntsiab lus, ntau hom, nrog rau qhov zoo thiab qhov tsis zoo, los pab cov neeg nyeem kom nkag siab txog cov txheej txheem vuam no.

Tack Welding yog dab tsi?

Lub tack weld yog ib ntus weld siv los tuav ob lossis ntau daim hlau rau hauv qhov chaw ua ntej ua qhov kawg weld. Txoj kev no feem ntau yog siv cov cua sov tsawg thiab luv luv vuam arc los koom nrog cov hlau ua ke.

Tsis tas li ntawd, lub hom phiaj ntawm cov txheej txheem no yog txhawm rau kho cov hlau kom raug ua ntej vuam. Thiab nws kuj tiv thaiv cov khoom txav los yog hloov thaum lub sij hawm vuam txheej txheem. Hauv lwm lo lus, nws tuaj yeem muab kev ruaj ntseg txaus kom tso cai rau tus welder ua kom tiav qhov kawg weld tiav. Yog li, vuam ib ntus yog ib qho tseem ceeb ua ntej cov kauj ruam hauv ntau daim ntawv thov vuam.

Tack Welding Ua Haujlwm Li Cas?

Nws yog ib qho kev paub uas cov txheej txheem vuam no feem ntau siv cov arc los kho ob daim. Yog li ntawd, tack welding yog ib qho yooj yim txheej txheem piv rau lwm tus, thiab hauv qab no yog qee cov kauj ruam.

• Kev npaj : Nws yog ib qho tseem ceeb kom nkag siab txog cov duab kos thiab cov kev cai ua ntej pib vuam. Tom ntej no, nws tseem yuav tsum tau xyuas kom meej qhov chaw vuam yog huv thiab tsis muaj lwm yam oxides.
• Tsis muaj Kev Kho: Portable arc welder zoo li MIG welder thiab TIG welder, feem ntau yog siv rau hauv cov txheej txheem no. Raws li, tus welder yuav kho qhov vuam tam sim no thiab qhov hluav taws xob kom haum rau cov tuab thiab hom vuam cov ntaub ntawv.
• Tacking : Qhov kub thiab txias tsim los ntawm arc welds yuav ua rau cov vuam hlau melting sai. Cov hlau ces txias sai sai thaum lub vuam tiav. Feem ntau, qhov ntev ntawm me me tack yog li ntawm ½ ntiv tes mus rau ¾ ntiv tes, thiab tsis pub ntau tshaj 1 ntiv tes.

Cov ntaub ntawv uas tuaj yeem Tack Welded

Feem ntau, cov welders feem ntau siv cov khoom siv hlau hauv cov txheej txheem tack welding. Txawm li cas los xij, peb yuav xaiv cov khoom tsim nyog thiab tsim nyog li cas? Cov ntsiab lus tseem ceeb nyob ntawm cov khoom siv thermal conductivity, susceptibility rau distortion thiab coefficient ntawm thermal expansion. Hauv qab no yog qee yam hlau.

• Carbon Steel
• Stainless hlau
• Aluminium
• Aluminium Alloy
• Hlau
• Tooj
• CuCrZr

Hom Tack Welds

Txhua hom tack weld ua haujlwm rau nws tus kheej daim ntawv thov thiab lub hom phiaj, thiab ntu no yuav qhia qee yam hom.

Standard Tack Weld

Hom vuam no tuaj yeem tiv taus cov khoom hnyav thiab tuav cov khoom kom ruaj khov rau qhov kawg vuam txheej txheem.

Choj Tack Weld

Feem ntau, cov welders feem ntau siv cov txheej txheem no thaum muaj qhov sib txawv me me ntawm ob cov ntaub ntawv hlau tom qab sib dhos. Hauv lwm lo lus, txoj kev no yog npaj los sau cov qhov khoob uas tshwm sim los ntawm kev txiav tsis raug lossis distortion.

Nov yog qee qhov kev txawj ntse hauv hom vuam: ua haujlwm me me ntawm txhua qhov tig, tso sijhawm txaus rau lawv kom txias.

Kub Tack Weld

Kub tacking zoo ib yam li choj tacking, raws li ob qho tib si cov tswv yim yog txhais los sau qhov khoob. Txawm li cas los xij, qhov sib txawv tseem ceeb yog qhov kub tacking xav kom tus welder siv lub sledgehammer los pounds rau hauv txoj hauj lwm kom zoo.

Thermit Tack Weld

Thermit welding yog txheej txheem uas siv cov tshuaj tiv thaiv exothermic los ua kom muaj qhov kub thiab txias, uas tuaj yeem ncav cuag li 4000 degrees Fahrenheit. Tsis tas li ntawd, nws kuj muaj kev sib xyaw ntawm cov khoom siv, xws li txhuas hmoov thiab hlau oxide hmoov.

Ultrasonic Tack Weld

Ultrasonic welding koom nrog kev siv cov tshuab hluav taws xob ntau zaus los tsim cov cua sov thiab fuse cov hlau ua ke. Cov kev vibrations nrawm tsim kev sib txhuam ntawm qhov sib cuam tshuam ntawm cov khoom siv hlau, uas ua rau cov cua sov hauv zos thiab melting. Nyob rau hauv cov txheej txheem no, cov welders tau ncaj qha thawb lub melted qhov chaw rau hauv lub hauv paus hlau yam tsis muaj ntxiv cov ntaub ntawv muab tub lim.

Cov ntaub ntawv ntawm Tack Weld

Muaj plaub hom tack weld. Xaiv cov qauv tsim nyog tuaj yeem pab txhim kho vuam efficiency thiab zoo. Yog li ntawd, qhov no yuav piav qhia lawv nyob rau hauv kom meej.

Square Tack Weld: Daim ntawv vuam no muab kev sib koom ua ke zoo los ntawm kev siv cov welds hauv cov qauv square, ua kom yooj yim rau kev sib koom ntawm ob qhov chaw nyob ntawm txoj cai kaum.

Vertical Tack Weld: Cov txheej txheem no suav nrog kev tso ib txoj kab ntsug tack weld uas khiav tag nrho qhov siab ntawm ob daim uas tau koom nrog, tsis yog ib qho chaw sib txuas ntawm qhov chaw.

Lub kaum sab xis Tack : Hom tack weld no yog siv los koom nrog ob daim hlau uas sib ntsib ntawm 90-degree kaum sab xis. Nws feem ntau yog siv los ua kom ruaj ntseg hauv qab cov hlau hauv qhov kev teeb tsa perpendicular.

Lub kaum sab xis Tack Weld: Welders feem ntau siv daim ntawv no los tiv thaiv kev tsim ntawm T-shaped sib koom ua ke ntawm cov khoom siv hlau perpendicular

Qhov zoo thiab qhov tsis zoo ntawm Tack Welding

Tack Welding thev naus laus zis ua rau muaj txiaj ntsig zoo, tab sis nws kuj muaj qee qhov kev txwv.

Qhov zoo ntawm Tack Weld

• Kev kho ib ntus: Cov khoom siv hlau raug kho ib ntus kom yooj yim rau txoj haujlwm raug.
• Kev ua tau zoo: Pab txhim kho kev ua haujlwm zoo rau nws txoj kev tswj xyuas yooj yim
• Tus nqi qis: Piv nrog rau lwm txoj kev vuam, tack welding tsis tshua kim.
• Kev thov dav: Haum rau feem ntau cov ntaub ntawv thiab tuaj yeem siv rau cov hlau qhov sib txawv thicknesses.

Cons ntawm Tack Weld

• Tsawg zog: Kev kho ib ntus tsis tuaj yeem hloov lub zog ntawm kev ua tiav qhov kawg vuam.
• Distortion: Kev tso cov tack weld tsis raug lossis ntau dhau tack weld loj tuaj yeem ua rau muaj kev cuam tshuam.
• Kev Txawj Ntse: Ua tau zoo tack welds yuav tsum muaj kev txawj thiab kev paub los ntawm tus welder.

Yuav Ua Li Cas Ua Tau Zoo Tack?

Qhov zoo tshaj plaws tack weld pab ua qhov kawg vuam zoo kawg nkaus vim nws tuaj yeem tiv thaiv cov ntaub ntawv los ntawm kev tawg lossis poob ntawm kev txav mus los. Yog li, ntu no yuav muab cov lus qhia dav dav rau koj kom ua tiav qhov zoo tack weld.

• Khaws cov hlau muab tub lim kom huv si, thiab xaiv ib lub xaim nrog lub cheeb me me.
• Xyuas kom paub tseeb tias qhov kev tiv tauj tsis pub hnav.
• Siv cov ntaub nplaum kom ruaj khov.
• Xyuas kom tus naj npawb ntawm tack welds phim qhov loj ntawm qhov vuam.
• Npaj qhov kev txiav txim thiab kev taw qhia ntawm cov welds.
• Siv lub siab voltage thaum ua kom nws ruaj khov.

Tack Welding vs Spot Vuam

Txawm hais tias ob lub vuam no zoo sib xws, lawv kuj muaj qee qhov sib txawv. Thiab qhov sib txawv tseem ceeb ntawm tack welding thiab qhov chaw vuam yog:

• Tack weld yog txheej txheem vuam ib ntus siv los tuav cov khoom hauv qhov chaw, thaum qhov chaw vuam yog cov txheej txheem vuam tsis kam uas tsim kom muaj kev sib koom ua ke, ncig vuam.
• Tack welds yog me me thiab ntiav, thaum qhov chaw welds muaj zog thiab ruaj khov dua.
• Tack welding feem ntau yog ua haujlwm rau kev sib dhos thiab sib dhos, thaum qhov chaw vuam yog nyob rau hauv daim ntawv thov ntau lawm
