Stick Welding Process Intro

SMAW (Shielded Metal Arc Welding) nthawi zambiri amatchedwa kuwotcherera ndodo.Ndi imodzi mwa njira zowotcherera zomwe zimagwiritsidwa ntchito masiku ano.Kutchuka kwake ndi chifukwa cha kusinthasintha kwa ndondomekoyi komanso kuphweka komanso mtengo wotsika wa zipangizo ndi ntchito.SMAW imagwiritsidwa ntchito kwambiri ndi zinthu monga chitsulo chofewa, chitsulo chosapanga dzimbiri, ndi chitsulo chosapanga dzimbiri.

Momwe Stick Welding Imagwirira Ntchito

Kuwotcherera ndodo ndi njira yowotcherera ya arc.Pamafunika electrode consumable kuti yokutidwa mu flux kuyala weld, ndi mphamvu ya magetsi ntchito kupanga arc magetsi pakati electrode ndi zitsulo kuti welded pamodzi.Mphamvu yamagetsi imatha kukhala yosinthira kapena yachindunji kuchokera kumagetsi opangira magetsi.

Pamene weld ikuyikidwa, zokutira za electrode flux zimasweka.Izi zimapanga nthunzi zomwe zimapereka mpweya wotetezera komanso wosanjikiza wa slag.Zonse za gasi ndi slag zimateteza dziwe la weld kuti lisaipitsidwe ndi mumlengalenga.Flux imathandizanso kuwonjezera zowotcha, deoxidizers, ndi alloying zinthu ku weld chitsulo.

Flux-Coated Electrodes

Mutha kupeza maelekitirodi okutidwa ndi flux mu mainchesi ndi utali wosiyanasiyana.Kawirikawiri, posankha electrode, mukufuna kufananitsa katundu wa electrode ndi zipangizo zoyambira.Mitundu ya ma elekitirodi okhala ndi flux imaphatikizapo mkuwa, mkuwa wa aluminiyamu, chitsulo chofewa, chitsulo chosapanga dzimbiri, ndi faifi tambala.

Kugwiritsa Ntchito Kuwotcherera Ndodo

SMAW ndiyotchuka padziko lonse lapansi kotero kuti imayang'anira njira zina zowotcherera pakukonza ndi kukonza.Akupitirizabe kugwiritsidwa ntchito kwambiri pakupanga mafakitale ndi zomangamanga zazitsulo, ngakhale kuti kuwotcherera kwa arc-flux-cored kukukula kwambiri m'maderawa.

Makhalidwe Ena Owotcherera Ndodo

Makhalidwe ena a Shielded Metal Arc Welding ndi awa:

• Imapereka kusinthasintha konse kwa malo
• Simakhudzidwa kwambiri ndi mphepo ndi ma drafts
• Ubwino ndi maonekedwe a weld amasiyana malinga ndi luso la woyendetsa
• Nthawi zambiri imatha kupanga mitundu inayi ya zolumikizira zowotcherera: cholumikizira chathako, cholumikizira pachiuno, T-joint, ndi fillet weld.
