Koj puas tau ntsib ib qho kev pom tsis meej xws li tawg loj thaum lub sijhawm vuam, thiab muaj ntau ntawm pores tom qab vuam? Thaum koj tseem tab tom xav txog seb nws puas yog vim yog qhov teeb meem ntawm Laser vuam txheej txheem kev ntsuas, koj puas yog ib qho tseem ceeb cuam tshuam rau weld tsim thiab ua haujlwm. Xaiv qhov zoo tshaj plaws vuam tiv thaiv cov roj ua tau zoo dua vuam zoo thiab cov kev ua tau zoo.
Txij li thaum Vuam kev thaiv cov roj av yog qhov tseem ceeb heev, tom qab ntawd: cov kev tiv thaiv roj? Yuav ua li cas xaiv cov hom thaiv pa roj? Kev tiv thaiv cov kev thaiv cov pa hluav taws xob sib tsoo hauv lub sijhawm vuam? Tom ntej no, hangao tech (sepo machinery) yuav ua rau txhua tus kom paub ntau ntxiv.
Lub luag haujlwm ntawm cov roj tiv thaiv
Nyob rau hauv laser vuam, thaiv cov roj yuav cuam tshuam WELD tsim, Weld zoo, Weld Nkag Mus tob thiab nkag mus rau qhov dav. Feem ntau, tshuab kev thaiv pa roj yuav muaj cov nyhuv zoo ntawm Weld, tab sis nws kuj tseem tuaj yeem ua kev puas tsuaj. Los ntawm cov nyhuv tsis zoo.
Cov teebmeem zoo
1) Lub tshuab ntawm kev thaiv hluav taws xob yuav tiv thaiv cov pas dej weld kom txo lossis tseem tsis txhob oxidation;
2) Lub tshuab hluav taws xob kom raug cov roj uas muaj peev xwm txo cov koob tawm los txo cov cuab yeej ua vuam;
3) Cov cua tshuab hluav taws xob muaj peev xwm txhawb nqa cov khaub ncaws sib kis ntawm chav Weld sib kis tau thaum lub sijhawm zoo nkauj thiab zoo nkauj;
4) Lub tshuab hluav taws xob kom raug cov hluav taws xob kom txo tau cov kev thaiv cov ntaub thaiv npog ntawm lub laser, thiab nce kev siv tus nqi siv ntawm lub laser;
5) Qhov tseeb ntawm kev thaiv cov roj yuav ua tau zoo txo cov vuam sam porosity.
Ntev npaum li cov hom pa nkev, roj ntws tawm, thiab hom kev raug xaiv tau raug xaiv, cov nyhuv xav tau tuaj yeem tau txais.
Txawm li cas los xij, kev siv hluav taws xob tsis yog yuav muaj cov kev tsis zoo ntawm vuam
1) Cov roj tiv thaiv tsis ncaj ncees yuav ua rau muaj kev cuam tshuam ntawm Weld:
①ngecting lub hom tsis muaj roj tsis zoo yuav ua rau cov kab nrib pleb hauv Weld, thiab kuj tseem yuav ua rau cov khoom siv hauv Weld kom txo qis;
②selecting cov roj av tsis ruaj khov yuav ua rau muaj oxidation ntau dua los yog me me), thiab tseem yuav cuam tshuam rau hauv Weld pas dej sab nraud thiab ua rau lub weld los tsoo lossis ua tsis ncaj;
③selping txoj kev siv roj tsis zoo yuav ua rau lub vuam sib dhos los yog tsis muaj kev tiv thaiv kev tiv thaiv lossis muaj qhov tsis zoo ntawm txoj kev sib tw;
2) Cov tshuab tiv thaiv roj yuav muaj qee cov txiaj ntsig ntawm Weld nkag, tshwj xeeb yog thaum vuam nyias daim hlau, nws yuav txo qhov kev nkag rau weld.
Cov Hom Tiv Thaiv Tiv Thaiv
Feem ntau yog siv cov roj av roj av rau n2, ar, nws, thiab tshuaj lom neeg sib txawv, thiab yog li lawv cov kev cuam tshuam ntawm Weld kuj txawv.
Nitrogen n2
Tus nqi yog qhov pheej yig tshaj, tab sis nws tsis haum rau vuam ib co hlau stainless. Ionization lub zog ntawm N2 yog ib nrab me ntsis, siab dua li ntawm ar thiab qis dua li ntawm nws. Raws li kev nqis tes ua ntawm laser, kawm tiav ionization yog qhov nruab nrab, uas tuaj yeem txo cov huab plasma huab thiab nce tus nqi siv tau zoo ntawm laser. Nitrogen muaj peev xwm siv tau cheev ib txwm muaj nrog txhuas alloy thiab carbon hlau ntawm ib qho kub, uas yuav ua rau muaj cov khoom siv tsis zoo, txo cov khoom siv tsis zoo ntawm cov khoom siv hluav taws xob ntawm kev sib koom ua ke. Yog li ntawd, nws tsis pom zoo kom siv nitrogen. Txhuas Alloy thiab Carbon Steel Welds muaj kev tiv thaiv.
Lub Nitride tsim los ntawm cov tshuaj lom neeg ntawm nitrogen thiab stainless hlau tuaj yeem ua rau lub zog ntawm kev sib koom ua ke ntawm Weld sib koom tes, uas yuav pab txhim kho cov khoom ntiag tug ntawm Weld. Yog li ntawd, cov nitrogen tuaj yeem siv los ua cov pa tiv thaiv thaum vuam stainless hlau.
Argon ar
Tus nqi pheej yig dua, qhov ceev tau siab dua, thiab cov nyhuv tiv thaiv zoo dua. Lub saum npoo ntawm cov weldment yog smoother dua helium roj, tab sis nws yog qhov cuam tshuam rau cov cua daj cua sov hnyav ionization. Herly hindly. Lub ionization lub zog ntawm AR yog tsawg, thiab cov ordization theem yog siab nyob rau hauv kev tsim ntawm Plasma huab, thiab yuav muaj qee yam cuam tshuam rau kev siv ntawm laser. Txawm li cas los xij, kev ua si ntawm Ar yog tsawg heev thiab nws yog qhov nyuaj rau kev sib tham nrog cov hlau. Tus nqi ntawm AR tsis yog siab. Tsis tas li ntawd, qhov ceev ntawm AR yog siab dua, uas tau txais txiaj ntsig zoo rau sab saum toj ntawm lub pas dej weld, yog li nws tuaj yeem siv los ua cov pa thaiv cov roj av.
Helium nws
Tus nqi yog kim kim dua, tab sis cov nyhuv yog qhov zoo tshaj plaws, yog li ntawd lub laser tuaj yeem dhau mus ncaj qha thiab mus txog ntawm qhov chaw ua haujlwm yam tsis thaiv. Ionization lub zog ntawm nws yog qhov siab tshaj plaws, thiab cov kev Ionization qib qis qis hauv laser, uas tuaj yeem tswj tau kev tsim cov huab plasma huab. Lub laser tuaj yeem ua ntawm cov hlau zoo heev, thiab cov haujlwm ntawm nws yog tsawg heev, thiab nws yeej tsis yog chemically reactic nrog hlau. Nws yog cov kev tiv thaiv zoo ntawm cov roj vuam, tab sis tus nqi ntawm nws siab dhau. Feem ntau, cov khoom lag luam ntau lawm yuav tsis siv cov roj no. Nws feem ntau yog siv rau kev tshawb fawb los yog cov khoom lag luam nrog cov nqi ntau.
Hangao Tech (Seko Machinery) muaj ntau dua 20 xyoo ntawm kev paub hauv Stainless hlau muaj yeeb nkab ntau lawm Kab Tube ua machine tsim kev lag luam. Lub paub tab R & D pab pawg thiab cov kws sib dhos ua ke yuav ua rau muaj kev sib dhos ua ke ntawm txhua kab ua ntej ua ntej ua zaub mov xa tuaj, yog li ua kom tiav cov khoom siv. Txwv txiav kev ua tau zoo thiab txo qhov nyuaj ntawm kev teeb tsa thiab debugging rau cov neeg siv khoom.
