Kuwotchereraelectrode imakhala ndi magawo awiri, pachimake ndi zokutira.Maelekitirodi azitsulo zowotcherera ali kunja kwa utoto (wophimba) kuthamanga kwa yunifolomu kumagwiritsidwa ntchito mosamala pachimake.Mitundu yosiyanasiyana ya kuwotcherera, kuwotcherera pachimake ndi kosiyana.Kuwotcherera elekitirodi pachimake zitsulo pachimake, pofuna kuonetsetsa khalidwe ndi ntchito ya kuwotcherera, butt pachimake zili zitsulo ali ndi malamulo okhwima, makamaka zili zonyansa zoipa (monga sulfure, phosphorous, etc.), payenera kukhala kukhala zoletsa okhwima kuposa zinthu m'munsi.Electrode mankhwala thumba amatchedwa weld zitsulo pachimake TACHIMATA pachimake.Waya wowotcherera nthawi zambiri amakhala ndi kutalika kwake komanso m'mimba mwake.Pamene soldering, kuwotcherera pachimake zimakhala ndi zotsatira ziwiri: Choyamba, kuchititsa kuwotcherera panopa, mphamvu arc amasandulika kutentha, wachiwiri pachimake waya wokha ntchito monga filler zitsulo ndi madzi osungunula kholo zitsulo maphatikizidwe weld amapangidwa.

Kupanikizika kumagwiritsidwa ntchito pamwamba pa zokutira zomwe zimatchedwa core solder coating.Kupaka kwa electrode kumagwira ntchito yofunika kwambiri pakuwotcherera.Kugwiritsa ntchito mankhwala opanda kuwala khungu ma elekitirodi kuwotcherera, ndondomeko kuwotcherera, mpweya ndi nayitrogeni mu mpweya adzakhala yaikulu kulowerera chitsulo chosungunuka, chitsulo chitsulo ndi zinthu zothandiza mpweya, pakachitsulo, manganese okusayidi ndi nitride mapangidwe oxides osiyanasiyana ndi nitrides, ndipo amakhalabe mu weld, weld slag, kapena kuyambitsa ming'alu.The kusungunuka mu chithaphwi cha mpweya kungayambitse kuchuluka kwa weld porosity, zinthu zimenezi akhoza kupanga mawotchi katundu wa weld (mphamvu, zimakhudza mtengo, etc.) kwambiri kuchepetsedwa, pamene weld Chimaona.

SMAW kuwotcherera maelekitirodi ntchito ❖ kuyanika ndi kuwotcherera pachimake wopangidwa ndi zigawo ziwiri.Pamene kuwotcherera, ndi kuwotcherera elekitirodi monga dzanja limodzi, ndi woyendetsa Arc panopa conduction kwenikweni, kuti pakati maelekitirodi ndi m'munsi zitsulo mu mosalekeza, khola arc, kupereka kutentha zofunika kusungunula solder.Komano, ndipo monga kuwotcherera filler zitsulo anawonjezera kuti weld kukhala chigawo chachikulu cha weld zitsulo.Choncho, zikuchokera kuwotcherera khalidwe ndi kuwotcherera, mankhwala zikuchokera zitsulo weld zimakhudza mwachindunji katundu makina ndi katundu thupi.Komanso, electrode imakhalanso ndi chikoka chachikulu pa kukhazikika kwa mawonekedwe a weld, njira yowotcherera monga kuwotcherera zokolola.
