Ultrasonic Impact Txhim Kho Weld Fatigue Performance Of Titanium

Ultrasonic Impact (UIT / UP) thev naus laus zis tau thov los ntawm lub ntiaj teb nto moo Ukrainian Paton Vuam Kev Tshawb Fawb Lub Tsev Haujlwm hauv xyoo 1972, thiab koom tes tsim los ntawm Paton Welding Research Institute thiab Lavxias "Quantum" Research Institute, thiab tau siv nyob rau hauv lub qub Soviet Union. txhawm rau txo cov kev ntxhov siab nyob hauv cov welds thiab kev qhia txog cov txiaj ntsig compressive kev ntxhov siab hauv cov nkoj tub rog.

Ultrasonic impact technology yog ib txoj kev ua tau zoo heev ntawm kev tshem tawm cov teeb meem seem tensile kev nyuaj siab thiab qhia tau zoo compressive stresses rau ntawm qhov chaw ntawm lub tivthaiv los yog nyob rau hauv lub weld cheeb tsam. Ultrasonic cuam tshuam cov cuab yeej siv lub zog muaj zog los tsav lub taub hau cuam tshuam nrog ntau zaus ntawm 20,000 zaug hauv ib ob qhov cuam tshuam rau saum npoo ntawm cov khoom hlau, muaj zog, ua haujlwm siab thiab tsom mus rau lub zog loj thiaj li hais tias qhov saum npoo ntawm cov hlau los tsim ib tug loj compressive yas deformation; Nyob rau tib lub sijhawm, ultrasonic cuam tshuam los hloov qhov kev ntxhov siab qub, ua rau muaj txiaj ntsig zoo compressive kev ntxhov siab; high-zog cuam tshuam ntawm qhov kub thiab txias ntawm cov hlau kom nce sai heev thiab tom qab ntawd txias txias kom ua rau cov nyhuv ntawm thaj tsam ntawm cov txheej txheem hlau hloov pauv, qhov chaw cuam tshuam los ntxiv dag zog rau saum npoo ntawm cov hlau. Qhov chaw cuam tshuam tuaj yeem ua kom muaj zog.

Nyob rau hauv lub tshav pob ntawm high-zog ultrasound (HPU), ultrasonic cuam tshuam tshuab tau dhau los ua ib qho kev cog lus kev tshawb fawb kev taw qhia, thiab cov Scope ntawm daim ntawv thov tau raug ncua mus rau ntau yam ntaub ntawv, Cheebtsam thiab vuam units. Txog tam sim no, ultrasonic cuam tshuam tshuab nyob rau hauv Russia, Ukraine, Fabkis, Nyiv, Norway, Sweden, Canada thiab lub tebchaws United States thiab lwm lub teb chaws nyob rau hauv railroads, marine engineering, tsheb, armored tsheb, hnyav siv machinery, machinery qhov chaw, aircraft, choj, dov Tshuag, roj pipelines, tshuaj machinery thiab khoom siv, thiab ntau lwm yam teb tau siv.

Kev cuam tshuam Ultrasonic yog kev siv lub zog hluav taws xob siab los txhawb cov cuab yeej cuam tshuam rau ntau tshaj 20, 000 zaus ntawm qhov thib ob zaus cuam tshuam rau saum npoo ntawm cov khoom hlau, vim yog ultrasonic high-frequency, high-efficiency thiab tsom nyob rau hauv lub zog loj, thiaj li hais tias qhov saum npoo ntawm cov hlau los ua ib tug loj siab-yas deformation; Nyob rau tib lub sijhawm, ultrasonic poob siab tsis hloov pauv qhov kev ntxhov siab qub, ua rau muaj qee qhov kev ntxhov siab compressive; kom cov ultrasonic cuam tshuam qhov yuav tsum tau ntxiv dag zog. Ultrasonic tsav fais fab mov los ntawm lub cable thiab teem rau hauv lub plhaub ntawm lub ultrasonic transducer txuas nrog lub vibration tso zis kawg ntawm lub transducer thiab amplitude pas nrig txuas nrog lub amplitude pas nrig kawg nruab nrog cuam tshuam koob. Lub ultrasonic tsav fais fab mov converts cov nqi hluav taws xob rau hauv high-frequency, high-voltage alternating tam sim no, uas yog kis mus rau lub ultrasonic transducer. Tom qab ntawd lub ultrasonic transducer yuav input hluav taws xob lub zog rau hauv txhua yam zog, uas yog, ultrasonic tsis, uas yog qhia nyob rau hauv daim ntawv ntawm transducer nyob rau hauv lub longitudinal kev taw qhia rau lub reciprocating telescopic zog; telescopic txav ntawm qhov zaus sib npaug rau lub zog tsav AC tam sim no zaus, telescopic hloov chaw hauv ntau tshaj li kaum microns los yog li ntawd. Lub luag hauj lwm ntawm lub amplitude pas nrig yog ua kom lub zog tso zis amplitude ntawm lub transducer, ncav cuag ntau tshaj 100 microns, ntawm qhov tod tes, qhov cuam tshuam ntawm rab koob cuam tshuam siv lub zog cuam tshuam los txhawb qhov cuam tshuam ntawm rab koob high-speed rau pem hauv ntej. Kev cuam tshuam rab koob cuam tshuam rau ntawm qhov chaw ua haujlwm, lub zog rau lub vuam seam hloov mus, txhawm rau tshem tawm lub luag haujlwm ntawm kev ntxhov siab sab hauv. Kev cuam tshuam lub taub hau los ntawm cov tshuaj tiv thaiv ntawm lub workpiece tom qab lub rebound, ua tau raws li high-frequency vibration ntawm lub amplitude lever, dua los ntawm excitation, thiab ib zaug dua ntawm kev kub ceev rau lub vuam, thiab lwm yam rau ntau zaus, ua kom tiav cov kev cuam tshuam ntawm kev ua haujlwm. Nta: siab zog, zoo cuam tshuam, muaj kev ntseeg siab, lub neej ntev kev pab cuam, lub teeb yuag, portable, yooj yim heev rau kev khiav lag luam zoo-tsim, dav siv lub zog txuag, txo nqi.
Kev ua tau zoo:

1, yog li ntawd cov residual tensile kev nyuaj siab nyob rau hauv lub nto txheej ntawm cov hlau weld yog hloov mus rau compressive kev nyuaj siab, li no ho nce lub zog qaug zog lub neej ntawm cov hlau qauv.

2, hloov txheej txheej txheej ntawm cov hlau nplej, kom cov yas deformation txheej, kom lub zog thiab hardness ntawm txheej txheej ntawm cov hlau yog ho txhim kho.

3, Txhim kho qhov geometry ntawm cov ntiv taw vuam thiab txo qhov kev ntxhov siab.

4, hloov lub vuam kev nyuaj siab, txo qhov vuam deformation, txhim kho qhov seem stability ntawm lub workpiece.
