Kugovera kwekushisa panguva yebutt welding chinhu chakakosha chinopesvedzera maitiro ekushongedza uye kunaka kwezvinoguma welds. Kunzwisisa kuti tembiricha inosiyana sei munzvimbo yese weld kwakakosha kune ma welders uye nyanzvi muindasitiri yewelding. Ichi chinyorwa chinoongorora kugoverwa kwetembiricha panguva yebutt welding, ichiratidza maitiro ayo pane weld zvivakwa uye ichipa manzwisisiro mukugadzirisa iyo welding maitiro.
- Tsanangudzo yeTemperature Distribution: Kugovera kwetembiricha kunoreva kugovaniswa kwekushisa kwakasiyana-siyana pajoini yeweld panguva yekugadzira welding. Iyo inotangira kubva kune yakakwirira-tembiricha yefusion zone kune yakaderera-tembiricha inopisa-yakakanganiswa nzvimbo (HAZ) uye yakapoterera base simbi.
- Fusion Zone: Iyo fusion zone ndiyo yepakati dunhu re weld uko tembiricha yepamusoro inosvika. Ndiyo nzvimbo inonyungudika simbi yepasi yobatana kuti iite bead. Kuve nechokwadi chekuisa kwakaringana kupisa munzvimbo ino kwakakosha kuti uwane kutendeseka kweweld.
- Nzvimbo Inokonzerwa Nekupisa (HAZ): Yakatenderedza nzvimbo yefusion, nzvimbo yakakanganiswa nekupisa inosangana nekudziya kwakadzika kana ichienzaniswa nenzvimbo yefusion. Kunyangwe isinganyunguduke, iyo HAZ inosangana nemetallurgical shanduko inogona kukanganisa ma mechanic properties.
- Residual Stress and Distortion: Kugovera kwetembiricha kunokanganisa kusara kwekushushikana uye kukanganisa mune welded chimiro. Kukurumidza kutonhora kweiyo fusion zone uye HAZ inogona kutungamira mukukoira uye kukonzeresa kushushikana, izvo zvinogona kukonzera kukanganisa kana kuputika.
- Preheating uye Post-Weld Heat Treatment (PWHT): Kudzora kugovera kwekushisa uye kuderedza zvingangoitika, preheating uye post-weld heat treatment (PWHT) inoshandiswa. Preheating inosimudza tembiricha yesimbi, kuderedza tembiricha gradient uye kuderedza kupisa kushushikana. PWHT inobatsira kudzoreredza kushushikana kwasara uye kudzoreredza zvivakwa zvezvinhu mushure mekugadzira.
- Kugadziridza Welding Parameters: Kugadzirisa maparamendi ekushongedza, senge welding ikozvino, voltage, kumhanya kwekufamba, uye kupisa kupinza, kunobvumira welder kudzora kugovera tembiricha. Sarudzo yakakodzera yeparamendi inogonesa yaunoda weld kupinda uye fusion uku ichideredza njodzi yekupisa kana kupisa.
- Kupinza Kwekupisa uye Hukuru hweChinhu: Iyo yekupisa yekuisa uye ukobvu hwezvinhu zvakare inokanganisa kugovera tembiricha. Zvishandiso zvakakora zvinogona kuda kupinza kupisa kwakanyanya, nepo zvitete zvinoda kudzorwa welding kudzivirira kupisa.
- Kuongorora uye Kudzora: Tembiricha dzemazuva ano dzinosanganisira tembiricha yekutarisa uye yekudzora masisitimu, ichigonesa chaiyo-nguva mhinduro pakugovera tembiricha. Izvi zvinogonesa zvigadziriso panguva yewelding process kuchengetedza yakanyanya tembiricha mamiriro.
Mukupedzisa, kugovera tembiricha panguva yebutt welding kunokanganisa zvakanyanya kunaka kweweld, kusara kunetseka, uye zvinhu zvemukati. Iyo inodzorwa zvakanaka tembiricha mbiri, kubva kunzvimbo yefusion kuenda kunzvimbo yakakanganiswa nekupisa uye yakatenderedza base simbi, yakakosha pakuwana ruzha welds. Welders anogona optimize tembiricha kugovera kuburikidza preheating, post-weld kupisa kurapwa, uye kugadzirisa welding paramita. Kutarisa uye kudzora tembiricha munguva chaiyo inosimudzira welding chaiyo uye inotungamira kune inowirirana uye yakavimbika welds. Nekunzwisisa kukosha kwekugovera tembiricha panguva yebutt welding, nyanzvi dzinogona kusimudza maitirwo ewelding, kuve nechokwadi chekuvimbika kwechimiro, uye kusangana neyakaomesesa welding zviyero. Kusimbisa kudzora tembiricha mukushanda kwewelding kunotsigira kufambira mberi mune simbi yekujoinha tekinoroji uye inosimudzira hunyanzvi muindasitiri yewelding.
