Cast iron welding rod inowanzo shandiswa kugadzirisa ganda reinjini, chivharo chemuviri, chigadziko chemuchina, mazino ekukanda anooneka vhiri kutyoka, kutsemuka, kupfeka, kukanganisa gomba welding matambudziko.Nekuda kwehuwandu hwekabhoni, chimiro chisina kuenzana, kusimba kwakaderera uye hurombo hwepurasitiki, simbi yakakandwa electrode chinhu chakashata cheldability zvinhu, zviri nyore kugadzira makatsemuka panguva yewelding, zvakaoma kucheka.Kuti uwane mhedzisiro inogutsa muwelding uye kugadzirisa welding yesimbi yakakandwa, zvakakosha kuterera kune "Three-part material and seven-part process", kwete chete kusarudza welding tsvimbo, asiwo kutora yakakodzera kugadzirisa welding nzira.
Iyo inotevera welding process inokurudzirwa sereferensi yesimbi yakakandwa welding uye kugadzirisa welding: 1, tanga wabvisa welding zvikamu zvesludge, jecha, mvura, ngura uye mamwe marara;Uye zvakare, iyo kabhoni-varombo layer uye oxide layer pamusoro pesimbi castings inoshanda pasi pePamusoro Tembiricha uye nharaunda yeutsi kwenguva yakareba inofanira kubviswa.2. Zvinoenderana nechimiro uye chakaremara rudzi rwechikamu chakashongedzwa, zviyero zvekugadzirira senge groove kuvhurika, kuputika kwekudzivirira kuchera gomba uye yakanyungudutswa dziva modelling inoitwa.3. Kune zvikamu zvinoda kutonhora kunopisa, preheat ivo pa 500-600 ° C, sarudza yakakodzera ikozvino, inopfuurira welding, chengetedza kupisa kwekutanga panguva yekugadzira welding, vhara zvinhu zvinodzivirira zvakadai seasbestos powder pakarepo mushure mekugadzira, uye vasiye. inotonhorera zvishoma nezvishoma, kuitira kuti ivandudze kupikisa kwayo uye kugadzirisa kushanda.4. Kunotonhora welding zvidimbu zvebasa, kudzivirira nheyo yesimbi kunyunguduka zvakanyanya, kuderedza maitiro echena, kudzivirira kupisa kwakanyanya, zvichiita kuti uwedzere kushushikana, diki ikozvino, pfupi arc uye narrow pass welding inofanira kushandiswa sezvinobvira ( kureba kwekupfuura kwega kwega hakufanirwe kudarika 50mm).Pakarepo welding sando weld kuzorodza kushushikana kudzivirira kutsemuka, kusvikira tembiricha yadonha kusvika 60 madhigirii C pazasi imwe weld.5, teerera kune arc hole paunenge uchivhara, kuitira kudzivirira kuvhara kwearc.
