Kev Tshawb Fawb Nrov ntawm Maven Laser | 10 Txoj Kev Siv Vuam Uas Siv Tau Ntau
- Kev Vuam Hlau Tiv Thaiv (SMAW)
Kev vuam hlau uas muaj hlau tiv thaiv yog ib qho ntawm cov txuj ci tseem ceeb tshaj plaws uas tus kws vuam yuav tsum paub. Yog tias tsis paub qhov txuj ci no zoo, yuav ua rau muaj ntau yam teeb meem hauv cov xov hlau.
- Kev Vuam Arc Hauv Qab Av (SAW)
Kev vuam siv submerged arc yog ib txoj kev vuam uas siv hluav taws xob arc ua qhov cua sov. Nws muaj qhov nkag mus tob, tsim khoom tau zoo thiab zoo heev: cov hlau yaj raug cais tawm ntawm huab cua los ntawm kev tiv thaiv slag, thiab kev ua haujlwm yog tshuab heev, ua rau nws tsim nyog rau kev vuam cov kab ntev ntawm cov qauv phaj nruab nrab thiab tuab.
- Gas Tungsten Arc Welding (GTAW/TIG)
Nov yog qee qhov kev ceev faj tseem ceeb rau GTAW:
(1) Ib txwm ua kom lub tungsten electrode ntse kom zoo. Lub electrode blunt yuav ua rau muaj hluav taws xob tawg thiab ua rau lub arc tsis ruaj khov, ua rau lub vuam puas tsuaj.
(2) Yog tias lub tungsten electrode nyob ze rau ntawm qhov vuam seam, nws yuav lo rau ntawm qhov workpiece; yog tias nws nyob deb dhau, lub arc yuav tawg, ua rau cov vuam dub, lub electrode hnav sai sai thiab muaj zog dua rau lub welder. Nws yog qhov zoo dua kom khaws nws ze li sai tau.
(3) Kev tswj lub cuab yeej yog ib qho kev txawj, tshwj xeeb tshaj yog rau kev vuam phaj nyias - tsuas yog qhov chaw vuam hauv qhov luv luv xwb. Tsis zoo li cov tshuab vuam tsis siv neeg nrog cov hlau pub thiab kev mus ncig tsis siv neeg, kev vuam tas mus li yuav hlawv thoob plaws hauv qhov chaw ua haujlwm.
(4) Kev pub hlau tes yuav tsum muaj kev xav zoo. Cov hlau vuam zoo tuaj yeem txiav los ntawm 304 stainless hlau ntawv nrog lub tshuab txiav es tsis txhob yuav cov hlau ua ntej-coiled; cov hlau ua ntej-coiled zoo, tau kawg, muaj nyob rau ntawm cov neeg muag khoom lag luam wholesale.
(5) Ib txwm ua haujlwm nyob rau hauv ib qho chaw uas muaj cua nkag tau zoo thiab hnav hnab looj tes tawv, khaub ncaws tiv taus hluav taws thiab lub kaus mom hlau vuam uas muaj qhov tsaus ntuj.
(6) Siv lub qhov (ceramic nozzle) ntawm lub teeb vuam kom thaiv lub teeb arc—tshwj xeeb, cia sab nraub qaum ntawm lub teeb tig rau koj lub ntsej muag ntau li ntau tau.
(7) Tus kws vuam hlau muaj kev nkag siab thiab kev kwv yees ua ntej ntawm qhov kub ntawm lub pas dej vuam, qhov loj me thiab kev ua haujlwm ntawm lub teeb.
(8) Siv cov tungsten electrodes uas muaj cim daj lossis dawb ua ntej, vim tias lawv xav tau kev txawj vuam siab dua.
- Kev Vuam Roj Oxy-Fuel (OFW)
Kev vuam siv roj oxy-fuel siv nplaim taws los ua kom cov hlau thiab cov hlau vuam kub ntawm qhov sib txuas ntawm cov hlau, yaj kom ua tiav kev vuam. Cov roj siv feem ntau suav nrog acetylene, roj av liquefied thiab hydrogen, nrog oxygen ua tus thawj oxidizer.
- Kev vuam laser
Kev vuam laser yog ib txoj kev vuam zoo thiab meej uas siv lub teeb laser muaj zog heev ua qhov chaw kub, thiab yog ib qho tseem ceeb ntawm kev siv tshuab ua cov khoom siv laser. Xyoo 1970, nws feem ntau yog siv rau kev vuam cov khoom siv nyias-phab ntsa thiab kev vuam qeeb qeeb. Cov txheej txheem vuam yog tswj los ntawm kev sib txuas: lub teeb laser ua rau qhov chaw ua haujlwm sov, thiab qhov kub ntawm qhov chaw sib kis mus rau sab hauv los ntawm kev sib txuas thermal. Los ntawm kev tswj cov kev teeb tsa xws li laser pulse dav, lub zog, lub zog siab tshaj plaws thiab qhov rov ua dua, cov khoom ua haujlwm yaj los ua ib lub pas dej vuam tshwj xeeb.
- Gas Metal Arc Vuam (GMAW/MIG/MAG)
Muaj ntau tus kws vuam xav tias GMAW yog txoj kev vuam yooj yim tshaj plaws vim nws tsis yooj yim nkag mus thiab yooj yim kawm. Feem ntau, tus neeg tshiab uas tsis muaj kev paub txog kev vuam tuaj yeem ua qhov chaw vuam yooj yim tom qab tsuas yog 2-3 teev ntawm kev qhia los ntawm tus kws tshaj lij.
Cov ntsiab lus tseem ceeb rau kev kawm GMAW: tuav tes kom ruaj khov, paub txog kev hloov pauv tam sim no thiab voltage, tswj qhov ceev ntawm kev vuam, thiab kawm cov tes taw kom raug (yooj yim tau los ntawm kev saib cov yeeb yaj kiab qhia). Kev paub txog cov txheej txheem vuam yuav cia koj ua tiav feem ntau ntawm cov haujlwm vuam.
- Kev Sib Txhuam Vuam
Kev sib txhuam vuam yog ib txoj kev uas siv cua sov los ntawm kev sib txhuam ntawm qhov chaw sib cuag ntawm cov khoom ua haujlwm ua qhov chaw kub, ua rau cov yas deformation ntawm cov khoom ua haujlwm nyob rau hauv lub siab kom ua tiav kev vuam.
Nyob rau hauv qhov siab tas li lossis nce ntxiv thiab lub zog torque, qhov kev txav mus los ntawm qhov kawg ntawm qhov vuam sib txuas ua rau muaj cua sov sib txhuam thiab cua sov yas deformation rau ntawm thiab ze ntawm qhov sib txhuam nto, ua rau qhov kub ntawm thaj chaw nce mus rau qhov ntau ze rau tab sis feem ntau qis dua qhov melting point. Qhov no txo cov khoom siv tsis kam deformation, ua rau plasticity nce thiab tawg cov zaj duab xis oxide ntawm qhov interface. Nyob rau hauv qhov siab upsetting, nrog rau cov yas deformation thiab ntws ntawm cov khoom siv, vuam yog ua tiav los ntawm intermolecular diffusion thiab recrystallization ntawm qhov interface - ua rau nws yog ib txoj kev vuam khov-xeev.
Feem ntau kev vuam siv txhuam muaj plaub kauj ruam: (1) hloov pauv lub zog kho tshuab mus rau hauv lub zog thermal; (2) kev hloov pauv yas ntawm cov khoom siv; (3) kev nce siab hauv qab cov xwm txheej thermoplastic; (4) kev sib kis ntawm cov khoom sib xyaw thiab kev rov ua dua tshiab.
- Kev vuam ultrasonic
Kev vuam ultrasonic xa cov nthwv dej vibrational siab mus rau qhov chaw ntawm ob lub workpieces uas yuav tsum tau vuam. Hauv qab kev siab, ob qhov chaw txhuam rau ib leeg kom tsim kev sib xyaw ntawm cov txheej molecular. Lub kaw lus vuam ultrasonic tiav feem ntau muaj lub tshuab hluav taws xob ultrasonic, transducer, horn, vuam taub hau sib dhos, pwm thiab thav duab.
- Kev Siv Tshuab Mos Mos
Kev sib txhuam thiab kev sib txuas siv cov hlau filler uas muaj qhov kub qis dua li cov hlau hauv paus. Cov khoom ua haujlwm thiab cov hlau filler raug cua sov rau qhov kub siab dua qhov kub ntawm cov khoom ua haujlwm tab sis qis dua qhov kub ntawm cov hlau hauv paus. Cov hlau filler uas yaj yuav ua rau cov hlau hauv paus ntub, puv qhov sib koom ua ke thiab sib kis nrog cov hlau hauv paus kom ua tiav kev sib txuas ntawm cov khoom ua haujlwm. Kev sib txhuam thiab kev sib txuas muaj qhov tsis zoo thiab du, zoo nkauj, ua rau lawv haum rau kev vuam precision, cov khoom sib xyaw thiab cov khoom sib dhos ua los ntawm cov ntaub ntawv sib txawv (piv txwv li, cov vaj huam sib luag honeycomb, cov hniav turbine, cov cuab yeej txiav cemented carbide thiab cov laug cam luam tawm). Raws li qhov kub ntawm kev vuam, kev sib txhuam thiab kev sib txuas raug muab faib ua ob pawg: cov txheej txheem nrog qhov kub ntawm kev vuam qis dua 450 ℃ hu ua kev sib txhuam mos, thiab qhov siab dua 450 ℃ hu ua kev sib txhuam nyuaj.
