Kuwotcherera ndi ntchito yofunika kwambiri pomanga zinthu zambiri zopangidwa ndi chitsulo ndi aluminiyamu.Kukhalitsa kwa dongosolo lonse ndi kupambana kwa polojekiti nthawi zambiri kumadalira ubwino wa weld.Choncho, kupatula zipangizo zoyenera, muyeneranso kudziwa momwe zinthuzo ziyenera kugwirizanirana nazo.Chimodzi mwazosintha munjira yonseyi ndi njira yowotcherera.Pazolinga za positiyi, tingoyang'ana pa kuwotcherera kwa arc ndi maelekitirodi okutidwa.
Kodi kuwotcherera arc pamanja ndi chiyani?
Njira yonseyi ndi yosavuta.Ndi imodzi mwa njira zowotcherera zotchuka kwambiri.Zimakhala kusungunula chivundikirocho pamodzi ndi electrode consumable ndi welded zinthu pogwiritsa ntchito arc magetsi.Ntchito zambiri zimachitidwa pamanja ndipo ubwino wa ntchitoyo umadalira luso la wowotchera.Komabe, pali zinthu zofunika kuziganizira ngati mukufuna kugwira ntchito mwaukadaulo.Muyenera kuyang'ana, mwa zina:
mwachindunji ndi alternating gwero panopa, mwachitsanzo wotchuka kuwotcherera makina
chingwe chokhala ndi ma electrode
chingwe chapansi chokhala ndi cholembera cha electrode
mtundu wa chisoti ndi zipangizo zina
Kupatula njira yowotcherera yokha, kusankha kwa ma electrode awiri a chinthu chowotcherera ndikofunikira kwambiri.Popanda izo, kupanga weld wabwino sikutheka.Kodi muyenera kusamala chiyani kuti musangalale ndi zotsatira zake?
Kusankha ma elekitirodi awiri pa workpiece - muyenera kudziwa!
Kusankhidwa kwa ma electrode awiri a chinthu chowotcherera mu njira ya MMA kumadalira makulidwe a weld kapena zinthu zomwe zikuwotcherera.Malo omwe mumawotcherera nawo ndiwofunikanso.Kawirikawiri, tingaganize kuti ma diameter amachokera ku 1.6mm mpaka 6.0 mm.Ndikofunikira kuti m'mimba mwake wa elekitirodi si upambana makulidwe a zinthu zomwe mukufuna kuwotcherera.Iyenera kukhala yaying'ono.M'mabuku pa kuwotcherera mudzapeza zambiri kuti awiri a elekitirodi ayenera kukhala lalikulu mmene ndingathere.Kusunthaku ndikokwera mtengo kwambiri.Choncho, zakuthupi ndi makulidwe a 1.5 mm kwa 2.5 mm bwino welded ndi elekitirodi ndi mtanda gawo la 1.6 mm.Nanga bwanji nthawi zina?
Zitsanzo za makulidwe azinthu ndi ma elekitirodi oyenera awiri.
Kuti muwone bwino pakusankhidwa kwa ma electrode awiri a chogwirira ntchito, m'munsimu mupeza mndandanda wazinthu zodziwika bwino kwambiri komanso ma elekitirodi awiri.
Kukula kwazinthu - Electrode diameter
1.5mm kuti 2.5mm - 1.6mm
3.0mm kuti 5.5mm - 2.5mm
4.0mm kuti 6.5mm - 3.2mm
6.0mm kuti 9.0mm - 4.0mm
7.5mm kuti 10mm - 5.0mm
9.0mm kuti 12mm - 6.0mm
