1, kuwotcherera kwa arc ya electrode
Kuwotcherera arc ndi imodzi mwa luso lofunikira kwambiri lomwe owotcherera ali nalo, ngati lusolo silili bwino, padzakhala zolakwika zosiyanasiyana mu msoko wowotcherera.
2, kuwotcherera kwa arc m'madzi
Kuwotcherera arc woviikidwa m'madzi ndi njira yowotcherera pogwiritsa ntchito arc ngati gwero la kutentha. Chifukwa cha kulowa mozama kwa arc woviikidwa m'madzi, ubwino wa kuwotcherera ndi wabwino: chifukwa cha chitetezo cha slag yosungunuka, chitsulo chosungunuka sichimakhudzana ndi mpweya, ndipo kuchuluka kwa ntchito ya makina ndi kwakukulu, kotero ndi koyenera kuwotcherera ma weld ataliatali a nyumba zapakati ndi zokhuthala.
3. Kuwotcherera kwa Argon arc
Nazi njira zina zodzitetezera pakuwotcherera kwa argon arc:
(1) Singano ya tungsten iyenera kunoledwa pafupipafupi. Ngati ili yosalala, mphamvu yamagetsi sidzakhala yolimba ndipo cholumikiziracho chidzatha.
(2) Ngati mtunda pakati pa singano ya tungsten ndi cholumikizira uli pafupi kwambiri, zimamatirana. Ngati uli kutali kwambiri, arc idzaphuka. Arc ikaphuka, idzayaka yakuda ndipo singano ya tungsten idzakhala yofiirira. Kuwala kwake nakonso kumakhala kwamphamvu. Ndi bwino kuisunga pafupi.
(3) Kulamulira switch ndi luso, makamaka pa kuwotcherera mbale zopyapyala. Ikhoza kuyatsidwa imodzi ndi imodzi. Iyi si makina owotcherera odziyendetsa okha omwe amayendetsa okha komanso amayatsa waya okha. Ngati ikuyaka nthawi zonse, idzatha.
(4) Muyenera kudyetsa waya. Izi zimafuna kukhudza. Waya wowotcherera wabwino kwambiri umadulidwa kuchokera ku mbale 304 pogwiritsa ntchito makina odulira. Musagule m'mabokosi. Zachidziwikire, mutha kupeza abwino m'malo ogulitsira zinthu zambiri.
(5) Yesetsani kugwira ntchito pamalo opumira mpweya, valani magolovesi achikopa, zovala, ndi chigoba chozimitsira mpweya chokha.
(6) Mutu wa ceramic wa mfuti yowotcherera uyenera kutetezedwa ku arc. Makamaka, mchira wa mfuti yowotcherera uyenera kuloza kumaso kwanu momwe mungathere.
(7) Ngati muli ndi chidziwitso ndi kuzindikira kutentha, kukula, ndi momwe dziwe losungunuka limagwirira ntchito, ndiye kuti ndinu katswiri wamkulu.
(8) Yesani kugwiritsa ntchito singano za tungsten zokhala ndi mabala achikasu kapena oyera, chifukwa izi zimafuna luso lapamwamba.
4. Kuwotcherera mpweya wa okosijeni
Kuwotcherera mpweya wa okosijeni ndi kugwiritsa ntchito malawi kutentha waya wachitsulo ndi wowotcherera pamalo olumikizirana a zitsulo kuti zisungunuke ndikukwaniritsa cholinga chowotcherera. Mpweya woyaka womwe umagwiritsidwa ntchito kwambiri ndi acetylene, mpweya wa petroleum wosungunuka ndi haidrojeni, ndipo mpweya wothandizira kuyaka womwe umagwiritsidwa ntchito kwambiri ndi mpweya.
5. Kuwotcherera ndi laser
Kuwotcherera kwa laser ndi njira yothandiza komanso yolondola yowotcherera yomwe imagwiritsa ntchito kuwala kwa laser kokhala ndi mphamvu zambiri ngati gwero la kutentha. Kuwotcherera kwa laser ndi chimodzi mwazinthu zofunika kwambiri pakugwiritsa ntchito ukadaulo wokonza zinthu za laser. M'zaka za m'ma 1970, imagwiritsidwa ntchito kwambiri powotcherera zinthu zokhala ndi makoma ochepa komanso kuwotcherera mwachangu. Njira yowotcherera ndi mtundu wa kutentha, ndiko kuti, kuwala kwa laser kumatenthetsa pamwamba pa chogwirira ntchito, ndipo kutentha kwa pamwamba kumafalikira mkati kudzera mu kutentha. Powongolera m'lifupi, mphamvu, mphamvu yayikulu komanso kuchuluka kwa kubwerezabwereza kwa kugunda kwa laser, chogwirira ntchitocho chimasungunuka kuti chipange dziwe linalake losungunuka.
