Zowotcherera Ma Parameters mu Makina Owotcherera a Butt

Zowotcherera zowotcherera zimagwira ntchito yofunika kwambiri pamakina owotcherera a matako, chifukwa amatanthauzira makonda omwe amafunikira kuti akwaniritse zotsatira zabwino kwambiri zowotcherera. Kumvetsetsa magawowa ndi kufunikira kwawo ndikofunikira kwa owotcherera ndi akatswiri pantchito zowotcherera. Nkhaniyi ikuyang'ana magawo omwe amawotcherera pamakina owotcherera a butt, kutsindika udindo wawo pakuwonetsetsa kuti ma welds olondola komanso apamwamba kwambiri.

1. Tanthauzo la Zigawo Zowotcherera: Zowotcherera zimatanthawuza kuchuluka kwa zinthu zomwe zimawongolera njira yowotcherera pamakina a matako. Izi zikuphatikizapo kuwotcherera panopa, voteji, liwiro chakudya waya, kutentha preheating, ndi interpass kutentha, pakati pa ena.
2. Welding Current and Voltage: Kuwotcherera panopa ndi magetsi ndi zinthu zofunika kwambiri zomwe zimatsimikizira kutentha kwa cholumikizira. Kuwongolera koyenera kwa zinthu izi kumatsimikizira kutentha koyenera komwe kumafunikira kuti muphatikizidwe bwino komanso kulowa mkati mwa weld.
3. Kuthamanga kwa Wire Feed: Kuthamanga kwa mawaya kumatengera kuchuluka komwe ma elekitirodi amalowetsedwa mu cholumikizira chowotcherera. Kusintha liwiro la chakudya cha mawaya ndikofunikira kuti zisankho zikhale zokhazikika ndikukwaniritsa kupanga mikanda yofananira.
4. Preheating Temperature: Preheating kutentha ndi kutentha komwe chitsulo m'munsi chimatenthedwa chisanayambe kuwotcherera. Ndi gawo lofunikira kwambiri popewa kusweka komanso kuchepetsa chiopsezo cha zovuta zobwera chifukwa cha hydrogen.
5. Kutentha kwa Interpass: Kutentha kwa Interpass kumatanthawuza kutentha kwachitsulo choyambira pakati pa mawotchi otsatizana. Kuwongolera kutentha kwa interpass ndikofunikira kuti muchepetse kuopsa kwa nkhani zokhudzana ndi kutentha ndikuwonetsetsa kusakanikirana koyenera pakati pa madutsa.
6. Shielding Gas Flow Rate: Munjira zomwe zimagwiritsa ntchito mpweya wotchinga, monga MIG kapena TIG welding, kuthamanga kwa gasi wotetezedwa ndi gawo lofunikira kwambiri. Kuyenda bwino kwa gasi kumatsimikizira chitetezo chokwanira cha dziwe la weld ku kuipitsidwa kwa mumlengalenga.
7. Mapangidwe Ophatikizana ndi Fit-Up: Mapangidwe ophatikizana ndi kukwanira ndi magawo ofunikira pamakina owotcherera matako. Kuphatikizika kokonzedwa bwino ndi koyenera koyenera kumatsimikizira kuwotcherera yunifolomu ndi kuphatikiza koyenera.
8. Chithandizo cha Post-Weld Heat (PWHT): Pazinthu zenizeni ndi ntchito, chithandizo cha kutentha kwapambuyo pa weld chikhoza kufotokozedwa muzowotcherera. PWHT imathandizira kuthetsa kupsinjika kotsalira ndikuwonjezera katundu wowotcherera.

Pomaliza, magawo owotcherera ndi zinthu zofunika kwambiri pamakina owotcherera a butt, kulamula zoikamo zomwe zimafunikira kuti zitheke bwino. Kuwotcherera pakali pano, voteji, liwiro la chakudya cha waya, kutentha kwa preheating, kutentha kwa interpass, kuteteza kuchuluka kwa gasi, kapangidwe kawo, kukwanira, ndi chithandizo cha kutentha kwapambuyo pa weld ndi magawo ofunikira omwe amathandiza kuti weld akhale wabwino komanso kukhulupirika. Mwa kutsata mwamphamvu zowotcherera ndikuwongolera mosamala magawowa, ma welds ndi akatswiri amatha kukwaniritsa ma welds olondola komanso apamwamba kwambiri pazogwiritsa ntchito ndi mafakitale osiyanasiyana. Kutsindika kufunika kwa magawo owotcherera kumatsimikizira kukhathamiritsa kwa ntchito zamakina a matako, zomwe zimapangitsa kuti pakhale njira zolumikizirana zodalirika komanso zodalirika.
