I. Ua ntej Vuam: Ua "Peb Daim Ntawv Teev thiab Peb Kho" txhawm rau muab lub hauv paus ruaj khov
1. Xyuas Cov Yeeb Nkab Kawg Zoo thiab Txhim Kho Beveling Standards: Lub yeeb nkab beveling lub kaum sab xis yuav tsum tau tswj ntawm 30℃thiab 45 degree, nrog rau ib qho -sab lub kaum sab xis sib txawv tsawg dua los yog sib npaug li 1.5 degree, thiab qhov sib dhos sib dhos yuav tsum tau khaws cia ntawm 2 ~ 4mm. Yog hais tias lub beveling yog asymmetrical (piv txwv li, ib sab muaj lub kaum sab xis me), lub sij hawm nyob ntawm lub vuam teeb ntawm ob sab yuav tsum tau kho los ntawm kev tswj qhov system. Rau txhua txhua 1℃qhov sib txawv, lub sij hawm nyob rau ntawm lub kaum sab xis me me yuav tsum raug txo los ntawm 10ms kom tsis txhob muaj kev sib txuam tsis zoo los yog cov hlaws vuam ntau dhau.
2. Txheeb xyuas cov khoom siv thiab txhim kho kev ua haujlwm ruaj khov: Txheeb xyuas tias lub vojvoog dabtsi yog khoov ntawm lub vuam teeb hluav taws xob yog ntau dua lossis sib npaug li 150 hli, thiab cov xaim pub hose tsis kinked; paub meej tias txhim khu kev qha hauv av, tsis muaj pa paug, thiab argon purity Ntau dua lossis sib npaug li 99.99%. Ua ntej pib lub tshuab, ua qhov system nws tus kheej- xyuas kom ntseeg tau tias servo lub cev muaj zog thiab cov sensors teb ib txwm.
3. Txheeb xyuas cov txheej txheem tsis ua haujlwm thiab txiav txim siab cov txheej txheem sib xws. Preset tam sim no, voltage, thiab mus ncig ceev raws li cov khoom (stainless steel / carbon steel), phab ntsa thickness, thiab vuam txoj hauj lwm (pav / ntsug / nyiaj siv ua haujlwm vuam). Piv txwv li:
Nyias-walled tube (tsawg dua lossis sib npaug li 3 hli): Tam sim no 80 ~ 120A, Voltage 12 ~ 16V
Nruab Nrab - tuab phab ntsa tube (6 ~ 10mm): Tam sim no 150 ~ 220A, Voltage 18 ~ 24V
Kev siv lub taub hau vuam txoj hauj lwm: Tsim nyog txo kev mus los, nce argon txaus tus nqi los ntawm 1 ~ 2L / min los tiv thaiv molten hlau los ntawm dripping.
II. Thaum lub sij hawm vuam: Master "peb stabilities thiab ib qho kev hloov kho" rau dynamic optimization.
1. Stabilize vuam torch centering. Tom qab pib, ua tib zoo saib seb lub welding torch puas haum rau qhov chaw vuam. Yog tias muaj qhov sib txawv, nws tuaj yeem hloov kho kom zoo ntawm cov chaw taws teeb tswj: nias lub pob sab xis kom txav mus rau sab laug, thiab sab laug khawm kom deviate rau sab xis (cov lus qhia tau thim rov qab thaum khiav rov qab) kom ntseeg tau tias cov hlaws hlaws yog qhov nruab nrab.
2. Stabilize lub pas dej ua ke molten. Saib xyuas qhov loj thiab fluidity ntawm lub pas dej molten. Yog tias lub pas dej loj dhau lawm, nws qhia tau tias qhov tam sim no siab dhau los yog qhov nrawm nrawm dhau, uas tuaj yeem ua rau kub hnyiab tau yooj yim - los ntawm; Yog hais tias nws yog me me heev, qhov tob tob tob yog tsis txaus. Lub xeev zoo tshaj plaws yog "teardrop" zoo li lub pas dej molten nrog lub ntsiab lus meej nkag mus rau hauv paus ntawm bevel.
3. Stabilize lub oscillation atherosclerosis. Rau qhov dav bevels, siv Z-zoo li tus lossis sawtooth oscillation, ua ke nrog qhov tsim nyog oscillation zaus thiab lub sijhawm nyob. Tam sim no, voltage, oscillation zaus, thiab mus ncig ceev ua ke txiav txim siab "fish scale" qauv tsim nyhuv- ruaj khov thiab tsis sib xws ceev yog qhov tseem ceeb.
4. Kho dynamic tsis. Yog tias lub pas dej molten pom tau tias tsis ncaj ncees rau ib sab, qhov hluav taws xob arc tuaj yeem hloov kho kom zoo (nce 0.5 ~ 1V ntawm sab tsis ncaj ncees) kom "rub rov qab" lub pas dej molten; me ntsis weld offset (tsawg dua los yog sib npaug li 1 hli) tuaj yeem raug kho hauv online los ntawm kev nkag mus rau "offset them nqi" ntawm lub vaj huam sib luag ua haujlwm.
III. Post-weld: Siv "peb qhov kev tshuaj xyuas thiab ib qho kev tiv thaiv" rau kev kaw - voj voog tswj.
Kev tshuaj xyuas qhov tshwm sim: Lub npoo npoo npoo yog tiaj thiab du, tsis muaj kab nrib pleb, porosity, slag inclusions, thiab cov npoo dov yog uniform. Kev lees txais Dimensional: Axis misalignment yog ib txwm, ntug misalignment tsawg dua los yog sib npaug li 10% ntawm phab ntsa tuab, thiab ntev raws li qhov siab ntev.
Sealing Txais: Kev ntsuas siab tau ua tiav; tsis muaj qhov xau tau pom thaum lub zog tuav.
Cov Khoom Siv Kho: Ntxuav vuam slag txhua hnub, tshawb xyuas qhov ncaj thiab vuam qhov chaw qhov tseeb txhua lub lim tiam, thiab ua kom tiav kev ntsuas txhua hli txhawm rau txuas cov cuab yeej siv tau ntev.
