Mutha kulumikizana nafe ngati mukufuna amakina owotcherera

(1) Zida zowotcherera zopangira ma arc kuwotcherera 1. Mapangidwe a ndodo yowotcherera Ndodo yowotcherera ndi electrode yosungunuka yomwe imagwiritsidwa ntchito powotcherera arc yamagetsi ndi zokutira.Amapangidwa ndi magawo awiri: ❖ kuyanika ndi kuwotcherera pachimake.

(L) Chowotcherera pachimake.Chitsulo chachitsulo chomwe chimakutidwa ndi ndodo yowotcherera chimatchedwa core welding.Pachimake chowotcherera nthawi zambiri ndi waya wachitsulo wokhala ndi kutalika kwake komanso m'mimba mwake.Pa kuwotcherera, pachimake kuwotcherera ali ndi ntchito ziwiri: imodzi ndi kuchita kuwotcherera panopa ndi kupanga arc kusintha mphamvu magetsi kutentha;chinacho ndikusungunula chitsulo chowotcherera chokha kukhala chitsulo chodzaza ndi kusakanikirana ndi chitsulo choyambira kupanga chowotcherera.

Waya wapadera wachitsulo womwe umagwiritsidwa ntchito pakuwotcherera ukhoza kugawidwa m'mitundu itatu: waya wachitsulo wopangidwa ndi mpweya, waya wachitsulo wopangidwa ndi aloyi ndi waya wosapanga dzimbiri.

(2) Khungu la mankhwala.Chophimba chomwe chimapanikizidwa pamwamba pa pachimake chimatchedwa chophimba.Kuphimba chophimba chopangidwa ndi mchere wosiyanasiyana kunja kwa ndodo yowotcherera kumatha kukhazikika arc.
