Titanium alloys ane yakaderera density, yakakwirira chaiyo simba, yakanaka ngura kuramba, yakaderera thermal conductivity, non-chepfu uye asiri magineti, uye anogona welded; dzinoshandiswa zvakanyanya mundege, aerospace, makemikari, peturu, magetsi, zvekurapa, zvekuvaka, zvemitambo nezvimwe minda.
Dzakajairwa nzira dzekuwelda dzetitanium uye titanium alloys dzinosanganisira: argon arc welding, yakadzika arc welding, vacuum electron beam welding, nezvimwe.
Kugadzirira musati welding
Unhu hwepamusoro hweiyo weldment uye titanium welding wire ine simba guru pamagetsi emhando yejoini yakasungwa, saka inofanira kunyatsocheneswa.
1) Mechanical kucheneswa: Kune mawelds asingade yakakwirira welding mhando kana yakaoma kugadzika, yakanaka sandpaper kana simbi isina tsvina mabhurashi anogona kushandiswa kupukuta iwo, asi zviri nani kushandisa carbide yero kukwenya ndiro yetitanium kubvisa iyo. oxide film.
2) Kucheneswa kwemakemikari: Usati waputirwa, chidimbu chekuyedza uye waya yekupisa inogona kubikwa. Mhinduro ye pickling inogona kuva HF (5%) + HNO3 (35%) mhinduro yemvura. Shamba nemvura yakachena mushure mekunhonga, uye weld pakarepo mushure mekuoma. Kana kuti shandisa acetone, ethanol, carbon tetrachloride, methanol, nezvimwewo kupukuta gorofu retitanium plate uye mativi ese (mukati me50mm imwe neimwe), pamusoro pewaya yewelding, uye chikamu chinosangana netitanium plate.
3) Kusarudzwa kwemidziyo yewelding: Kune argon arc welding yetitanium uye titanium alloy tungsten mahwendefa, DC argon arc welding magetsi sosi ine hunhu hwekunze uye yakakwirira-frequency arc kutanga kunofanirwa kusarudzwa, uye kunonoka kuburitsa gasi nguva haifanirwe kunge iri pasi pe. 15 masekondi kudzivirira oxidation uye kusvibiswa kweiyo weldment.
4) Kusarudzwa kwezvinhu zvewelding: Kuchena kweargon gasi kunofanirwa kunge kuri pasi pe99.99%, dova rinofanira kunge riri pazasi -40 ℃, uye huwandu hwese hwehutsvina hunofanira kunge huri 0.001%. Kana dzvinyiriro iri mu argon cylinder inodonha kusvika pa 0.981MPa, inofanirwa kumiswa kudzivirira kukanganisa kunaka kwejoint yakasungwa.
Xinfa welding midziyo ine hunhu hwemhando yepamusoro uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
5) Kudzivirirwa kwegasi uye tembiricha yekudziya: Iyo titanium pombi yejojo yakaderera panguva yewelding. Kuti udzivise iyo welded joint kuti isasvibiswa nemagasi anokuvadza uye zvinhu patembiricha yakakwira, nzvimbo yewelding uye weld inofanira kuiswa pasi pekuchengetedzwa kwewelding inodiwa uye tembiricha yekudzora, uye tembiricha inofanira kunge iri pasi pe250 ℃.
Operating Instruction
1. Paunenge uchiita manual argon arc welding, iyo shoma angle (10 ~ 15 °) inofanira kuchengetedzwa pakati petambo yewelding uye weldment. Waya yewelding inofanira kudyirwa mudziva rakanyungudutswa zvishoma nezvishoma uye zvakaenzana nechekumberi kwedziva rakanyungudutswa, uye kupera kwewaya yewelding haifanirwe kubviswa kunze kwenzvimbo yekudzivirira yeargon.
2. Kana welding, pfuti yewelding haina kuzungunuka yakatwasuka. Kana ichida kuzununguka, iyo frequency inofanirwa kuve yakaderera uye swing amplitude haifanirwe kunge yakakura kwazvo kudzivirira kukanganisa kuchengetedzwa kweargon gasi.
3. Pakutyora arc uye kupedza weld, ramba uchipfuura argon kudzivirira kusvikira weld uye simbi iri munzvimbo inopisa inotonhora kusvika pasi pe350 ℃ usati wabvisa welding pfuti.
Muvara wepamusoro we weld uye inopisa-yakakanganiswa nzvimbo
1. Weld zone
Silver white, light yellow (inobvumirwa kune yekutanga, yechipiri uye yechitatu level welds); yakasviba yero (inobvumidzwa yechipiri neyechitatu level welds); yegoridhe yepepuru (inobvumirwa kune yechitatu level welds); rima bhuruu (hazvibvumirwi kune yekutanga, yechipiri uye yechitatu level welds).
2. Nzvimbo yakakanganiswa nekupisa
Silver white, light yellow (inobvumirwa kune yekutanga, yechipiri uye yechitatu level welds); yakasviba yero, yegoridhe yepepuru (inobvumirwa yechipiri neyechitatu level welds); bhuruu yakasviba (inobvumidzwa kune yechitatu level welds).
