Tsib txoj kev ntawm titanium alloy vuam thiab yuav ua li cas xaiv

Titanium alloy yog hais txog ntau yam hlau alloy uas ua los ntawm titanium thiab lwm yam hlau, thiab yog cov khoom siv hlau uas muaj cov khoom zoo heev. Titanium yog ib qho tseem ceeb ntawm cov hlau tsim nyob rau hauv 1950s. Titanium alloys muaj lub zog siab, zoo corrosion kuj, thiab kub kub kuj. Nws yog dav siv hauv aerospace, aviation, tshuaj lom neeg kev lag luam, roj av, hluav taws xob fais fab, kev kho mob, kev tsim kho, khoom ua si thiab lwm yam. Lub vuam ntawm titanium alloy yog ib qho tseem ceeb ua technology, tab sis nws kuj yog ib qho nyuaj heev technology. Vim tias titanium alloys tau yooj yim ua rau cov ntsiab lus xws li oxygen, nitrogen, thiab hydrogen ntawm qhov kub thiab txias, ua rau txo qis hauv vuam zoo thiab kev ua haujlwm tsis zoo. Yog li ntawd, welding ntawm titanium alloys yuav tsum tau tshwj xeeb txoj kev thiab cov cuab yeej los xyuas kom meej qhov kev ncaj ncees thiab kev cia siab ntawm lub vuam. Niaj hnub no peb qhia tsib txoj hauv kev rau vuam titanium alloys:

Qhov no yog arc vuam txoj kev uas siv cov uas tsis yog-melting tungsten electrode thiab inert roj tiv thaiv. Nws yog qhov tsim nyog rau kev sib koom ua ke ntawm titanium thiab titanium alloy daim hlau, cov kav dej thiab cov khoom tshwj xeeb uas muaj qhov tuab ntawm 0.5 ~ 10mm. Lub kaum sab xis thiab lub puab tsaig vuam. Qhov zoo ntawm txoj kev no yog qhov zoo tshaj plaws weld zoo, me me deformation, hloov tau yooj yim, thiab tsis xav tau cov khoom siv hlau. Qhov tsis zoo yog tias qhov chaw vuam muaj cov kev cai nruj thiab yuav tsum tau ua raws li kev tiv thaiv roj argon. Txwv tsis pub, nws yuav ua rau muaj kuab paug xws li oxidation thiab nitration ntawm cov vuam, yog li kev noj cov roj argon loj heev.

Qhov no yog ib txoj kev uas siv high-speed electrons los bombard nto ntawm lub workpiece los ua kom muaj zog cua sov kom ua tiav vuam. Nws yog tsim rau pob tw thiab kaum pob qij txha ntawm titanium thiab titanium alloy daim hlau, cov kav dej thiab cov khoom tshwj xeeb zoo li tus nrog lub thickness ntawm 0.1 ~ 150mm. thiab lap welding. Qhov zoo ntawm txoj kev no yog tias nws tuaj yeem nqa tawm hauv lub tshuab nqus tsev, tsis txhob muaj pa phem, muaj qhov sib txawv ntawm qhov tob-rau-dav qhov sib piv ntawm vuam, me me deformation, thiab kev ua haujlwm siab. Qhov tsis zoo yog tias cov cuab yeej siv tau yooj yim thiab kim, yuav tsum tau npaj ua haujlwm siab, thiab tsis haum rau cov workpieces loj lossis complex-shaped workpieces.

Qhov no yog ib txoj kev siv tau zoo thiab meej vuam uas siv high-zog-density laser beams raws li qhov chaw tshav kub. Nws yog tsim rau pob tw thiab kaum pob qij txha ntawm titanium thiab titanium alloy daim hlau, cov kav dej thiab cov khoom tshwj xeeb zoo li lub thickness ntawm 0.1 ~ 10mm. thiab lap welding. Qhov zoo ntawm txoj kev no yog tias nws tuaj yeem nqa tawm hauv cov huab cua, tsuas yog yuav tsum muaj kev tiv thaiv sab-blown inert gas, loj weld qhov tob-rau-dav piv, me me deformation, thiab kev kub ceev. Nws tuaj yeem paub txog kev ua haujlwm tsis siv neeg lossis neeg hlau thiab tuaj yeem siv rau hauv lub hnab looj tes lossis lub tshuab nqus tsev. Nqa tawm los tsim ib qho chaw inert gas los yog lub tshuab nqus tsev ib puag ncig kom tau txais txiaj ntsig zoo dua thiab zoo dua vuam. Qhov tsis zoo yog tias nws muaj cov kev cai nruj ntawm kev ua haujlwm tshem tawm, tsis haum rau tuab-wall welding, thiab tsim nyog rau vuam ntawm titanium alloy precision lug.

Qhov no yog arc vuam txoj kev uas siv high-temperature thiab high-ceev plasma arc raws li ib tug kub qhov chaw. Nws yog tsim rau pob qij txha, cov pob qij txha thiab cov pob qij txha ntawm titanium thiab titanium alloy daim hlau, cov kav dej thiab cov khoom tshwj xeeb uas muaj qhov tuab ntawm 0.5 ~ 15mm. Lap vuam. Qhov kom zoo dua ntawm txoj kev no yog tias nws tuaj yeem nqa tawm hauv huab cua, thiab tsuas yog yuav tsum tau tshuab nrog inert roj tiv thaiv ua ntej thiab tom qab. Weld seam muaj qhov sib piv loj-rau-dav, me me deformation, thiab kev ua haujlwm siab. Qhov tsis zoo yog tias cov cuab yeej siv tau yooj yim dua thiab yuav tsum muaj qhov siab dua xws li nozzle aperture, ion gas flow rate, thiab vuam ceev, thiab tsis haum rau workpieces nrog nkhaus nto los yog qhov sib txawv ntawm cross-sections.

Qhov no yog ib txoj kev uas siv tsawg melting point hlau raws li muab tub lim kom tiav hlau kev twb kev txuas yam tsis melting lub hauv paus hlau. Nws yog tsim rau titanium thiab titanium alloy daim hlau, cov kav dej thiab cov kav dej nrog lub thickness ntawm 0.1 ~ 3mm. Butt, ces kaum thiab ncej puab vuam ntawm tshwj xeeb-puab qhov chaw. Qhov kom zoo dua ntawm txoj kev no yog tias nws tuaj yeem nqa tawm ntawm qhov kub thiab txias, tsis txhob cuam tshuam cov cheeb tsam kub thiab cov pa phem, muaj qhov deformation me me, thiab tuaj yeem ua tiav ntau txheej lossis ntau qhov kev sib txuas. Qhov tsis zoo yog tias nws yuav tsum tau siv cov flux tshwj xeeb thiab cov fillers, yuav tsum tau ua kom huv si ntawm qhov chaw ua haujlwm, thiab tsis haum rau cov pob qij txha nrog cov khoom loj lossis kev ua haujlwm siab.
Cov saum toj no tsib txoj kev vuam sib txawv, thiab peb tuaj yeem xaiv raws li qhov xwm txheej tshwj xeeb. Rau cov kev lag luam tshwj xeeb, peb pom zoo kom siv cov tshuab laser vuam: 1. Cov khoom siv hauv tsheb, nkoj, kev kho mob thiab lwm yam. 2. Cov khoom siv hauv hluav taws xob, kev sib txuas lus, biology thiab lwm yam. 3. Cov khoom tseem ceeb hauv aerospace, nuclear zog, tshuaj lom neeg kev lag luam thiab lwm yam kev lag luam. 4. Cov khoom tseem ceeb hauv aerospace, nuclear zog, tshuaj lom neeg kev lag luam thiab lwm yam kev lag luam.

Nws tuaj yeem siv rau hauv kev sib dhos vuam ntawm micro thiab me me workpieces uas tsim nyob rau hauv loj qhov ntau rau automated ntau lawm. (Qhov tsawg kawg nkaus lub teeb pom kev tuaj yeem ncav cuag 0.1mm)
5. Rau cov ntaub ntawv refractory xws li titanium alloy thiab quartz, laser vuam yog yooj yim heev thiab cov nyhuv zoo heev.
6. Thaum vuam cov ntaub ntawv nyias lossis cov xov hlau zoo, tsis muaj teeb meem meltback zoo li arc vuam.
7. Nws yog ib qho yooj yim rau automate high-speed welding thiab tuaj yeem tswj tau digitally lossis hauv computer.

Yuav kom suav tau, muaj ntau yam hauv kev xaiv titanium alloy vuam txoj kev. Xaiv txoj kev vuam tsim nyog tsim qhov chaw vuam zoo rau titanium alloy vuam. Vim yog cov yam ntxwv ntawm kev kub ceev, siab zog thiab siab precision ntawm laser vuam, nws yog ib qho kev xaiv rau titanium alloy vuam. Qhov kev xaiv zoo tshaj plaws.
