Paunenge uchicheka kabhoni simbi, laser yekucheka michina inowanzo shandisa ebetsero magasi kubatsira mukushanda.Magasi anowanzo anobatsira iokisijeni, nitrogen uye mweya.Ndeupi musiyano uripo pakati pemagasi matatu aya pakucheka carbon steel?
Kuti unzwisise kukanganisa kwegasi rimwe nerimwe rinobatsira pakucheka, zvakakosha kujekesa musimboti webasa remagasi anobatsira.Chokutanga pane zvose zvakanakira kushandisa mhepo yekucheka zvakajeka zvakakwana, hapana mari inodiwa.Paunenge uchishandisa mhepo, chete magetsi emagetsi emhepo compressor uye muchina pachawo unofanirwa kuverengerwa, kubvisa mutengo wakakwira wemagasi anobatsira.Iko kushanda kwekucheka pamapepa matete kunofananidzwa neiyo yenitrogen yekucheka, zvichiita kuti ive yehupfumi uye inobudirira yekucheka nzira.Zvisinei, kucheka kwemhepo kunewo zvipingamupinyi zviri pachena maererano ne-cross-section.Chekutanga, iyo yakachekwa nzvimbo inogona kuburitsa maburrs, ayo anoda yechipiri kugadzirisa kuchenesa, kukuvadza kutenderera kwese kwekugadzirwa kwechigadzirwa.Chechipiri, nzvimbo yakachekwa inogona kuve yakasviba, iyo inokanganisa kunaka kwechigadzirwa.Laser kugadzirisa pachayo kunotora mukana wekubudirira uye kunaka kwemhando, uye zvipingamupinyi zvekucheka kwemhepo zvakaita kuti vatengi vazhinji vasiye rudzi urwu rwekucheka.
Chechipiri, kushandiswa kwekucheka okisijeni, kucheka okisijeni ndiyo yakajairika uye yechinyakare nzira yekucheka.Kushandiswa kweokisijeni fiber laser yekucheka muchina mabhenefiti ayo anonyanya kuratidzwa mumutengo wegesi, mukugadziriswa kwekabhoni simbi-yakavakirwa pepa simbi, pasina kazhinji kutsiva magasi anobatsira, kuwedzera kucheka kwekuita, kutonga kuri nyore.Zvisinei, kukanganisa ndekwekuti mushure mekucheka kweokisijeni, pachava nechidimbu che oxide firimu pamusoro pekucheka kwepamusoro, kana chigadzirwa ichi chine oxide firimu zvakananga kune welding, nguva ichave yakareba, iyo oxide firimu ichabva yaputika, iyo chigadzirwa chichagadzira welding yenhema, inokanganisa kunaka kwekushongedza.
Apo okisijeni inoshandiswa segasi rinobatsira, firimu re oxide rinoumbwa panzvimbo yekucheka.Kumusoro kweokisidhi-isina kuchekwa kunowanzo kuchena uye kunogona kukwenenzverwa zvakananga, kupendwa, nezvimwewo. Iyo yakasimba yekushongedzwa kwecorrosion inoitawo kuti kushandiswa kwayo kuve kwakakura kwazvo.
Iyo iri pamusoro yekucheka data ndeyekutarisa chete, iyo chaiyo yekucheka mhedzisiro ichakunda.
Muchidimbu, kana uchicheka gobvu kabhoni simbi mahwendefa pamusoro pe6mm, kucheka okisijeni chete kunotsigirwa.Paunenge uchicheka pasi pe 6mm, kana pane zvakajeka zvinodiwa zvekucheka kwehutano uye kururamisa, zvinokurudzirwa kushandisa nitrogen yekucheka, iyo inonyanya kushanda uye inogona kugadziriswa zvakananga munhanho inotevera, asi kucheka kweokisijeni kunononoka uye kusingakurudzirwi.Paunenge uchicheka pasi pe 6mm, kana kucheka chete kunofungidzirwa kana kuti pasina maitiro akajeka anodiwa, kucheka kwemhepo kunokurudzirwa, ne zero mutengo wegesi.
