Welding distortion idambudziko rakajairika rinosangana neakasiyana-siyana welding process, kusanganisira simba rekuchengetedza welding michina. Kupisa kunogadzirwa panguva yewelding kunogona kukonzera kuwedzera kwezvinhu uye kubvongodzwa, zvichitungamira kune zvisingadiwe deformation muzvikamu zvakasungwa. Ichi chinyorwa chine chinangwa chekuongorora mazano ekugadzirisa nemazvo uye kuderedza kukanganiswa kwewelding mumashini ekuchengetedza magetsi. Nekushandisa maitiro akakodzera, ma welders anogona kuve nechokwadi chekuti ekupedzisira welded zvimiro zvinosangana nezvinodiwa uye kushivirira.
- Welding Sequence uye Tekinoroji: Yakafanira welding kutevedzana uye hunyanzvi hunogona kukanganisa zvakanyanya kuitika uye ukuru hwekushatisa welding. Izvo zvakakosha kuronga kutevedzana kwewelding nenzira inodzikisira kuunganidzwa kwezvakasara zvinonetsa uye kupisa kwemafuta. Mawelder anofanirwa kufunga kutanga kubva pakati uye kuenda kunze kana kushandisa nzira yekudzokera kumashure kugovera kupisa zvakaenzana. Pamusoro pezvo, kushandisa intermittent welding matekiniki uye kudzikisira huwandu hwewelding pass inogona kubatsira kuderedza kukanganisa.
- Fixture uye Clamping: Kushandisa akakodzera zvigadziriso uye clamping matekiniki kwakakosha pakudzora welding kukanganisa. Fixtures inopa rutsigiro uye kubatsira kuchengetedza inodiwa kurongeka panguva yewelding. Maitiro ekugadzirisa akakodzera, senge tack welding kana kushandisa jigs akasarudzika, anogona kubatsira kuchengetedza maworkpiece munzvimbo chaiyo, kuderedza kufamba uye kukanganisa panguva yewelding process.
- Preheating uye Post-Weld Heat Treatment: Preheating the base material before welding inogona kubatsira kuderedza tembiricha gradient uye kuderedza kukanganiswa. Iyi tekinoroji inonyanya kushanda kune zvakakora zvinhu kana kana welding dissimilar simbi. Saizvozvo, post-weld heat yekurapa matekiniki, senge stress annealing, inogona kushandiswa kudzoreredza kushushikana kwasara uye kuderedza kukanganisa. Iyo chaiyo preheating uye kupisa kurapwa parameters inofanirwa kuve yakatarwa zvichienderana neiyo zvinhu zvivakwa uye welding zvinodiwa.
- Welding Parameters uye Joint Dhizaini: Kugadzirisa maparamita ewelding, senge kupisa kwekuisa, kumhanya kwewelding, uye kusarudzwa kwesimbi yekuzadza, kunogona kukanganisa mazinga. Welders anofanirwa kukwirisa aya ma paramita kuti awane chiyero pakati pekupinda, fusion, uye kukanganisa kutonga. Pamusoro pezvo, dhizaini yakabatana inogona kuita basa rakakosha mukuderedza kukanganisa. Kushandisa nzira dzakadai sechamfering, grooving, kana kushandisa kaviri-sided welding approach inogona kubatsira kugovera kupisa uye kuderedza kukanganisa kukanganisa.
- Post-Weld Distortion Correction: Muzviitiko izvo welding distortion isingadzivisike, post-weld distortion kururamisa nzira dzinogona kushandiswa. Izvi zvinosanganisira matekiniki akadai sema mechanical kutwasanudza, kupisa kutwasanudza, kana kuti localized re-welding. Zvakakosha kuziva kuti post-weld kugadzirisa nzira dzinofanirwa kushandiswa nekuchenjerera uye nenyanzvi dzine ruzivo kuti dzirege kukanganisa kutendeseka kwechimiro che welded.
Welding kukanganisa idambudziko rakajairika rinotarisana nenguva yewelding process, uye magetsi ekuchengetedza welding michina hazvisi izvo. Nekushandisa nzira dzakakwana dzewelding, kushandisa zvigadziriso uye kusungirira, kufunga preheating uye post-weld kupisa kurapwa, optimize welding paramita, uye kushandisa post-weld kukanganisa kururamisa nzira pazvinenge zvichidikanwa, welder vanogona kunyatso gadzirisa uye kuderedza kukanganiswa kwewelding. Izvo zvakakosha kuti unzwisise iyo chaiyo yezvinhu zvivakwa, dhizaini yekubatana, uye welding zvinodiwa kuti ugadzire nzira dzakakodzera dzekudzora kukanganisa uye kuve nechokwadi chemhando uye kuvimbika kwezvikamu zvakashongedzwa.
