(1) kuwotcherera arc pansi pamadzi
Kuwotcherera kwa arc pansi pamadzi kumagwiritsa ntchito waya wopitilira chakudya ngati ma elekitirodi ndi zitsulo zodzaza.Kuwotcherera, kumtunda pamwamba pa weld zone, yokutidwa ndi wosanjikiza wa granular flux, moto arc mu flux wosanjikiza wa mapeto gawo la waya ndi tsankho m'munsi zakuthupi anasungunuka ndipo anapanga kuwotcherera.Pansi pa kutentha kwa arc yamagetsi, kumtunda kwa slag kusungunuka kwa solder ndi metallurgical reaction kumachitika ndi zitsulo zamadzimadzi.Slag akuyandama pamwamba pa osungunuka zitsulo kusamba, Komano, angathenso kupanga dzanja limodzi kuteteza weld zitsulo, kuteteza kuipitsidwa kwa mpweya, ndi kupanga thupi ndi mankhwala anachita ndi chitsulo chosungunula, kusintha kwambiri ndi katundu wa weld zitsulo;weld zitsulo koma pang'onopang'ono Ling.Kuwotcherera kwa arc pansi pamadzi kumatha kugwiritsidwa ntchito ndi kuwotcherera kokulirapo.Poyerekeza ndi kuwotcherera kwa arc pamanja, mwayi waukulu kwambiri ndiweld wabwino, kuthamanga kwambiri.Choncho, makamaka oyenera msoko kuwotcherera lalikulu workpiece girth.Ndipo kwambiri makina kuwotcherera.Kuwotcherera arc pansi pamadzi kwagwiritsidwa ntchito kwambiri pakuwotcherera chitsulo cha kaboni, chitsulo chochepa cha aloyi ndi chitsulo chosapanga dzimbiri.Olowa slag akhoza kuchepetsa mlingo kuzirala, zina mkulu-mphamvu structural zitsulo, mkulu mpweya zitsulo kumizidwa arc kuwotcherera angagwiritsidwe ntchito.

(2) kuwotcherera kwamphamvu kwambiri
Yemweyo pafupipafupi kuwotcherera ndi olimba kukana kutentha mphamvu.Resistor matenthedwe kuwotcherera, ntchito mkulu-pafupipafupi panopa kwaiye mu workpiece kuti pamwamba pa workpiece weld zone ndi usavutike mtima ndi kusungunuka kapena pafupi ndi pulasitiki boma, ndiye ntchito (kapena osagwiritsidwa ntchito) kukhumudwitsa mphamvu kukwaniritsa kumanga. zitsulo.Chifukwa chake ndi gawo lolimba ndi njira yowotcherera yokana.Kuwotcherera kwafupipafupi molingana ndi mawonekedwe apamwamba kwambiri kuti apange kutentha mu workpiece akhoza kugawidwa kuti agwirizane ndi kuwotcherera kwafupipafupi ndi kulowetsedwa kwa kuwotcherera kwafupipafupi.Kukhudzana ndi kuwotcherera mkulu-pafupipafupi, mkulu pafupipafupi panopa kudzera kukhudzana ndi workpiece makina ukubwera workpiece.Kulowetsedwa kwa mawotchi apamwamba kwambiri, ma frequency apamwamba kwambiri kudzera pa chogwirira ntchito, kuphatikizika kwa koyilo yakunja mkati mwa chogwiriracho kumapangitsa kuti pakhale magetsi.High-frequency kuwotcherera ndi amphamvu mwapadera njira kuwotcherera, malinga ndi mankhwala ali ndi zida zapadera.High zokolola kuwotcherera liwiro la 30m/mphindi.Makamaka ntchito kupanga mipope welded kotenga nthawi msoko kapena ozungulira msoko.
