Ndi mitundu iti yayikulu yamakina achitsulo omwe alipo?

Makina azitsulo zachitsulo amaphatikizapo mitundu ingapo yogwirizana ndi njira zosiyanasiyana zopangira ndi kupanga. Zina mwa mitundu yodziwika bwino ndi:

- **ERW (Electric Resistance Welding) Makina Opangira Mapaipi**: Mphero za ERW zimagwiritsa ntchito mafunde amagetsi kuti apange ma welds motsatira msoko wazitsulo, kupanga mapaipi. Njirayi imaphatikizapo kudutsa mzerewu kudzera muzodzigudubuza kuti zikhale chubu chozungulira, ndikutsatiridwa ndi kuwotcherera kwafupipafupi kuti agwirizane m'mbali. Makina a ERW ndi osinthasintha, amatha kupanga mapaipi okhala ndi ma diameter osiyanasiyana komanso makulidwe a khoma oyenera kugwiritsidwa ntchito pomanga, zomangamanga, ndi mafakitale amagalimoto.

- **Mapaipi Opanda Msoko**:Mpherozi zimagwira ntchito popanga mapaipi opanda zitsulo opanda ma welds aatali. Njirayi imayamba ndi kutenthetsa ma cylindrical steel billets mpaka kutentha kwambiri ndiyeno kuwaboola kuti apange chipolopolo chopanda kanthu. Chigobacho chimadutsa ndikugudubuza ndi kukula kuti chikwaniritse miyeso ndi katundu wofunidwa. Mapaipi opanda msoko amadziwika chifukwa cha mphamvu zawo zazikulu, zofanana, komanso kuyenerana ndi ntchito zomwe zimafuna kukana kupanikizika, monga mapaipi amafuta ndi gasi ndi machubu a boiler.

- **HF (High Frequency) Mapaipi Owotcherera**: Mphero zowotcherera za HF zimagwiritsa ntchito kutentha kwapang'onopang'ono kupanga zowotcherera muzitsulo zachitsulo. Njirayi imaphatikizapo kudutsa mzerewu kudzera pa koyilo yolowera yomwe imapanga magetsi, kutenthetsa m'mphepete mwa chingwecho mpaka kutentha kwa welding. Kukakamiza kumagwiritsidwa ntchito popanga weld, kupanga mapaipi bwino ndi zinyalala zazing'ono. HF kuwotcherera nthawi zambiri amagwiritsidwa ntchito popanga mapaipi azinthu zamagalimoto, mipando, ndi ntchito zamapangidwe.

- **Mapaipi Owotcherera a Laser**: Makina owotcherera a laser amagwiritsa ntchito ukadaulo wapamwamba wa laser kuti akwaniritse ma welds olondola komanso apamwamba kwambiri pamapaipi achitsulo. Njirayi imagwiritsa ntchito matabwa a laser kuti asungunuke ndikuphatikiza m'mphepete mwazitsulo kapena machubu popanda kukhudzana. Mapaipi opangidwa ndi laser amawonetsa kupotoza pang'ono, mphamvu zowotcherera kwambiri, ndipo ndi abwino kwa mapulogalamu omwe amafunikira kukongola kwapamwamba komanso mtundu wa weld.
