Kev tawg vuam ntawm Titanium Clad Steel Phaj: Txheej Txheem thiab Kev Tswj Xyuas Zoo

Lub hauv paus ntsiab lus ntawm Explosion Vuam

Kev tawg vuam koom nrog ob lub hlau los ntawm kev tsav lub phaj cladding mus rau lub substrate ntawm siab tshaj tawm nyob rau hauv ib oblique lub kaum sab xis. Lub detonation ntawm ib txheej ntawm explosive accelerates lub flyer phaj, thiab nyob rau hauv sib tsoo taw tes ib nyias dav hlau ntawm hlau yog ejected los ntawm ob qhov chaw, tshem tawm oxide films thiab exposing hlau huv si. Ob qhov chaw ces khi rau hauv cov khoom hauv lub xeev nyob rau hauv lub siab heev, tsis muaj bulk melting. Lub resulting interface muaj ib tug yam ntxwv wavy morphology uas xauv cov hlau ua ke mechanically thiab metallurgically. Vim hais tias cov ntaub ntawv weld nyob rau hauv ib feem ntawm ib tug thib ob, dissimilar hlau uas tsis tuaj yeem fusion welded, xws li titanium ntawm carbon steel, tuaj yeem koom nrog cov cheeb tsam loj.

Cov khoom siv rau cladding thiab substrate

Cov txheej txheej cladding, hu ua cov phaj sib xyaw lossis cov ntawv tshaj tawm, yog xaiv rau corrosion lossis yaig tsis kam. Cov ntaub ntawv cladding muaj xws li titanium thiab titanium alloys, npib tsib xee-raws li alloys, stainless hlau, duplex stainless hlau, tooj liab thiab txhuas. Lub substrate, los yog lub hauv paus phaj, feem ntau yog carbon steel los yog tsawg- alloy steel xaiv rau cov qauv muaj zog thiab nqi. Phaj qhov ntau thiab tsawg thiab thickness ua ke yog customized raws li tus neeg yuav tsum tau muaj. Lub phaj cladding yuav tsum loj dua li cov substrate hneev taw vim hais tias cov npoo yog trimmed tom qab vuam kom tshem tawm qhov tsis sib haum xeeb ciam teb.

Kev npaj nto ua ntej vuam

Surface condition tswj daim ntawv cog lus zoo. Lub substrate yog thawj zaug ntxuav ntawm daim tawv nqaij oxide nrog lub log abrasive, tom qab ntawd hauv av thiab polished kom du, tsis xws luag -dawb tiav. Lub phaj cladding tau txais kev kho tib yam ntawm nws lub ntsej muag sib txuas. Ob qhov chaw yuav tsum tsis muaj xeb, roj, nplai thiab noo noo vim tias txhua qhov kev sib kis yuav raug daig ntawm qhov sib cuam tshuam thiab ua rau thaj chaw tsis muaj kev cuam tshuam. Qhov twg cov cladding yuav tsum tau welded rau hauv loj panels ua ntej cladding, argon arc vuam nrog siab -purity argon yog siv, thiab cov welds yog av flush thiab tshuaj xyuas ua ntej tawg kauj ruam.

Txheej txheem Parameters thiab chaw teeb tsa

Qhov sib txawv ntawm qhov sib tsoo vuam yog xaiv rau txhua qhov khoom sib xyaw ua ke: qhov sib nrug deb ntawm cov phaj, hom thiab thauj khoom ntawm qhov tawg, qhov nrawm nrawm, thiab qhov tshwm sim ntawm kev sib tsoo lub kaum ntse ntse thiab cuam tshuam tshaj tawm. Qhov sib txawv standoff, ua nrog spacers nyob ib ncig ntawm lub phaj npoo, muab lub flyer phaj chav kom ceev ua ntej yuav cuam tshuam. Detonation yog pib los ntawm ib tug ntug thiab cheb hla lub phaj ntawm ib tug tswj ceev ceev uas ua rau lub sib tsoo lub kaum sab xis nyob rau hauv lub qhov rais sib txuas. Kev ua haujlwm yog nqa tawm ntawm qhov chaw muaj ntawv tso cai nyob deb, feem ntau ntau tshaj kaum mais ntawm thaj chaw nyob, ntawm cov av mos uas tsis muaj pob zeb kom lub hauv qab ntawm lub phaj tsis puas los ntawm kev poob siab. Kev nyab xeeb tawg ua raws li cov cai hauv zos rau kev tuav cov khoom tawg thiab tiv thaiv cov neeg ua haujlwm.

Ncej - Weld Processing and Inspection

Tom qab detonation lub clad phaj yog ntxuav thiab tshuaj xyuas los ntawm ultrasonic kuaj rau daim ntawv qhia kev sib raug zoo thiab unbonded cheeb tsam. Cov cheeb tsam uas tsis muaj kev sib txuas tau raug cim thiab kho, feem ntau yog siv los ntawm kev sib txuas los yog los ntawm re-cladding nrog ib qho kev sib txuas, thiab tom qab ntawd lub phaj raug kho yog tias xav tau. Thaum tshav kub kub-kev kho kub thiab lub sij hawm nyob ntawm seb cov ntaub ntawv cladding thiab substrate, txij li thaum titanium-steel interfaces tuaj yeem tsim nkig intermetallic theem yog overheated. Tom qab kev kho cua sov lub phaj yog straightened los ntawm cov menyuam leveling los yog xovxwm flattening, ces kuaj ib tug thib ob lub sij hawm los ntawm kev kuaj ultrasonic kom paub meej tias cov txheej txheem straightening tsis pib tawg. Thaum kawg lub phaj yog trimmed, cov npoo yog npaj los ntawm kev txiav thiab polishing, thiab cov khoom tiav dhau qhov seem thiab qhov chaw soj ntsuam ua ntej ntim thiab xa khoom. Kev lees txais cov txheej txheem rau titanium clad phaj tau txhais hauv ASTM B898 thiab, rau kev siv lub nkoj siab, hauv NB / T 47002.

Cov lus nug nquag

1. titanium puas tuaj yeem tawg welded ncaj qha rau carbon steel?

Yog lawm. Kev tawg vuam yog cov txheej txheem tsim khoom rau titanium-clad steel phaj vim tias cov khoom- lub xeev daim ntawv cog lus tsis muaj melting uas yuav tsim cov titanium nkig- hlau tebchaw hauv fusion vuam.

2. Dab tsi yog qhov raug shear zog ntawm clad interface?

Rau titanium- steel clad phaj, daim ntawv cog lus shear lub zog feem ntau yuav tsum muaj tsawg kawg yog 140 MPa, thiab daim ntawv cog lus raug txheeb xyuas los ntawm kev tshuaj xyuas ultrasonic dhau ntawm thaj chaw tag nrho ntxiv rau kev kuaj xyuas ntawm daim coupon.

3. Vim li cas qhov chaw tawg yuav tsum nyob deb ntawm cov tsev?

Lub detonation ua rau muaj zog shock yoj thiab hauv av vibration. Cov kev cai yuav tsum muaj qhov chaw nyob deb nroog uas muaj kev nyab xeeb ntawm ob peb mais ntawm cov tsev nyob, thiab cov av mos uas tsis muaj pob zeb los tiv thaiv lub phaj saum npoo los ntawm kev puas tsuaj.

4. Cov teeb meem dab tsi raug kuaj los ntawm kev kuaj ultrasonic tom qab vuam?

Unbonded cheeb tsam, inclusions thiab delaminations ntawm lub interface. Cov cheeb tsam uas tsis muaj kev sib koom ua ke raug cim, kho thiab rov ua dua - sim kom txog rau thaum cov qauv kev lees paub ntawm cov qauv siv tau.

5. Puas yog kev kho cua sov ib txwm xav tau tom qab tawg vuam?

Tsis yog ib txwm, tab sis nws yog ib txwm muaj rau cov tuab lossis hardenable substrate steels thiab rau kev ntxhov siab ua ntej straightening. Qhov kub yog txwv los ntawm cov txheej txheem cladding, tshwj xeeb tshaj yog titanium, kom tsis txhob tsim cov nkig interfacial compounds.

6. Cov qauv twg tswj hwm titanium clad phaj?

ASTM B898 npog reactive thiab refractory hlau clad phaj, thiab NB / T 47002 npog clad daim hlau rau cov hlab ntsha siab hauv Suav code daim ntawv thov. Cov neeg yuav khoom yuav tsum qhia meej tias qhov kev lees paub twg siv tau.
