Ruzhinji rweO-ring fractures inoitika muzvisimbiso zvakaputirana.O-mhete imhando yerabha chisimbiso chepamusoro chine denderedzwa muchinjikwa-chikamu, chikamu chemuchinjiko chakaumbwa neO, saka chinodaidzwa kuti O-ring, chisimbiso chinoshandiswa zvakanyanya mu hydraulic uye pneumatic sealing systems.Kana zvinhu zvechisimbiso zvikaita brittle, zvisinei, hapana kuomerera kwakasimba kune welding yakatarwa uye kupisa kurapwa, kusagadzikana kutsemuka kunogona kuitika nyore.Kana kusarudzwa kwezvinhu zvisina kunaka uye mafomu ezvimiro asina kugadzirwa kuti asangane nesaiti tembiricha uye kudzvanywa kunogona kukonzera kutsemuka zviitiko.Panguva yekushandiswa, iyo yekuisa chisimbiso inotarirwawo nekupaza zviitiko senge hydrogen embrittlement.
Saka O-ring fractures ichiri kugadziriswa here?Mhinduro yakajeka ndeyokuti hongu, kutanga kwezvose, tinofanira kunyatsobvisa kuputika, kunyange kutsemuka kuduku kunofanira kuva kwakajeka uye kwakachena, kururamisa kuona muviri gloss, hapana kukanganisa kusvika ikozvino.Iyo yakawandisa ine guruva zvinhu inofanira kubviswa, yakanamirwa nepurasitiki yakanaka welding tsvimbo yobva yadimburirwa kuita murwi kuti idzivirire.Kana iyo yakaturikidzana weld kutsemuka maitiro echikamu chemidziyo, iyo yakaturikidzana weld yezasi layer ichishandisa dhizaini yakanaka yepurasitiki yeiyo shanduko layer, inogona kudzivirira pamusoro pedhiri rekutsemuka.Iyo weld inofanira kunge ipfupi sezvinobvira kuderedza kupisa kwakakanganiswa nzvimbo uye kudzivirira deformation yekuisa chisimbiso pamusoro pe (chisimbiso).Asati cladding weld kuti preheat, pashure welding insulation kunonoka kutonhora, kudzivirira kudzivirira mhepo muhoro, kudzivirira welded chisimbiso pamusoro.Mushure mekunonoka kutonhora, wozogadzirisa uye kugadzira.
Ammonia igasi rinodzivirira risina kubatwa nesimbi newaya, uye simbi uye alloy muwaya hazvitsvairwe.Iyo inopisa yakakanganiswa nzvimbo idiki uye haikonzeri slag uye porosity mune yakafukidzira layer, uye deformation idiki.Welding nozzle uye chisimbiso pamusoro kuchengetedza yakakura kana vertical angled, kuitira kuti mhinduro nguva dzose akaiswa pasi kudzivirirwa giremu gasi, welding pfuti kuita kumwe kuzununguka, waya zvokudya zvinofanira yunifomu.Pakupera kwekuzadza kwepamusoro, zvishoma zvishoma welding waya inofanira kuwedzerwa.Wobva wadhonza zvishoma nezvishoma uchidzivirira pfuti uchisimudza, mushure mekunge dziva rakanyungudutswa ratonhora zvishoma, rega kudyisa gasi kuti upedze kugadzirisa.
