Vuam Tshuab Ntawm Titanium Tube

1.Thaum vuam vuam, cov cua kub tso zis me me yuav tsum xaiv nyob rau hauv cov txheej txheem tsim nyog, thiab qhov kub ntawm cov khaubncaws sab nraud povtseg yuav tsum tsis txhob siab tshaj 200 ℃ kom tiv thaiv cov kua siv lead ua los ntawm kev loj hlob mus ntev rau ntawm qhov kub.

2.Qhov lub vuam ntawm seamless titanium cov kav dej yuav tsum tau ua nyob rau hauv kev tiv thaiv argon: lub viav vias tsau nozzle yog siv los tiv thaiv tus pas nrig pas nrig, lub teeb nyem npog tiv thaiv lub qhov txuas kub thiab sab nraud ntawm thaj chaw ze-sib koom, thiab cov yeeb nkab yog sau nrog argon los tiv thaiv lub weld thiab Sab hauv sab hauv ntawm thaj chaw ze ze, kev ntsuas tshwj xeeb: thaum welding cov yeeb nkab uas muaj qhov loj dua, cov neeg ua haujlwm hauv cov yeeb nkab hnav lub npog ntsej muag roj thiab tuav cov ntaub npog los tiv thaiv sab nraub qaum weld pas; thaum welding cov yeeb nkab nrog lub taub me dua lossis cov chaw nres nkoj ruaj ruaj, Sab hauv sab hauv yog ntim nrog soluble ntawv ntawm qhov deb ntawm 150-300mm los ntawm qhov zawj (qhov twg yog qhov ntau dua raws li kev ua haujlwm), thiab tom qab ntawd lub pob ntawm cov ntawv soluble yog ntxig txhawm rau tiv thaiv cov pa cua hauv lub raj kom tsis txhob puas, thiab tom qab ntawd tau sau nrog roj cav argon Cov pa hauv cov yeeb nkab tau sab lim. Argon roj yuav tsum tau muaj kev npaj ua ntej ua ntej vuam, thiab argon yuav tsum tau ncua kev txuas tom qab vuam kom txias qhov kub ntawm thaj chaw kub thiab tiv thaiv kom tsis txhob muaj oxidation.

3.Qhov qhov muab tub lim hlau yuav tsum nco ntsoov khaws cia hauv qab kev tiv thaiv ntawm argon thaum lub sijhawm ua haujlwm vuam. Lub vuam hlau yuav tsum tsis raug rau cov cua nrawm nrawm tom qab lub arc raug tua, thiab yuav tsum tau tawm thaum lub weld tawm ntawm kev tiv thaiv. Yog tias cov hlau hlau txhuam cov hlau tsis huv, ua rau oxidized thiab tshem tawm, cov ntu paug yuav tsum tau muab tshem tawm.

4.Tsis txhob ignite arc lossis kuaj arc nyob rau sab ntawm weldment; kom ntseeg tau qhov zoo ntawm arc pib thiab kaw thaum lub sijhawm vuam; sau txog txoj kev sib tsoo ntawm arc thaum kaw lub arc, thiab stagger interlayer pob qij txha ntawm ntau cov txheej txheem vuam.

5. Dhau ntawm qhov tshwj xeeb xav tau, txhua lub weld yuav tsum tau welded txuas ntxiv nyob rau hauv ua ke. Yog tias nws cuam tshuam rau qee qhov laj thawj, nws yuav tsum tau kuaj xyuas thaum rov txuas lub hlau, thiab vuam tuaj yeem txuas ntxiv tom qab paub tseeb tias tsis muaj keej.

6.Yog hais tias tungsten ntsib qhov tsis zoo thaum lub sijhawm ua haujlwm vuam, lub sijhawm ua haujlwm vuam yuav tsum nres, lub ntsej muag tungsten yuav tsum tau muab tshem tawm nrog lub grinder, thiab tungsten-qib kawg tuaj yeem rov ua haujlwm dua. Kev ua haujlwm vuam tuaj yeem ua haujlwm rov qab tom qab ncav tau qhov yuav tsum tau ua. Cov yuav tsum yog tib yam li pib kev ua haujlwm vuam.

7.Yog ib qho ntawm cov xwm txheej hauv qab no tshwm sim nyob rau hauv qhov chaw vuam ntawm titanium kav dej, lub vuam yuav tsum nres thaum kev tiv thaiv kev tiv thaiv tsis raug coj:

1) Cov cua nrawm ≥2m / s

2) Cov av noo txheeb ze dua 90%

3) Nws los nag thiab daus;

4) Qhov ntsuas kub qis dua 0 ° C.

8.Qhov vuam vuam kho cov txheej txheem yog tib yam li cov thawj vuam txheej txheem. Tus lej ntawm kev rov kho rau tib ntu tsis yog ntau tshaj ob. Yog tias yuav tsum tau kho thib ob, yuav tsum tsim cov txheej txheem kho. Nws yuav tsum tau nqa tawm tom qab kev pom zoo los ntawm tus thawj tswj xyuas lub luag haujlwm vuam, thiab yuav tsum tau qhia nyob rau hauv cov ntaub ntawv tsim kho.
