Yepakati kabhoni simbi kazhinji inoreva kune kabhoni yemukati inosvika 0.25 kusvika 0.60% kabhoni simbi.Manual arc welding yekabhoni simbi yekukanda uye welding yeakanyanya maficha seanotevera:

(1) Chigadziko chesimbi padhuze nenzvimbo yeweld inoita kuderera kwepurasitiki yenyama yakaoma.Iyo yakakwirira iyo kabhoni yemukati, kukora kweplate, ndiko kukura kwemaitiro akaomarara.Weldment yakaoma, kukurumidza kutonhora uye kusarudzwa kwetsvimbo haisi iyo nguva, inotonhora kutsemuka.

(2) Sezvo base simbi yakanyunguduka muchikamu chekutanga che weld metal ratio inosvika makumi matatu muzana, saka iyo yakakwira kabhoni yemukati we weld, mhedzisiro yacho iri nyore kupinza simbi inopisa kuputika uye kuputika kutonhora.

Matanho anotorwa nekutungidzwa kwekabhoni simbi

(1) Kana zvichiita, sarudza maelectrodes akaderera-hydrogen.Maelectrode akadaro uye kupikisa kwakanyanya kutonhora kupemha kuramba kune thermal cracking capacity.Mhosva dzemunhu mumwe nemumwe, nekunyatso kudzora tembiricha yekupisa uye kuderedza kuderedzwa kwesimbi yepasi penetration weld kabhoni yemukati uye mamwe maitiro matanho, kushandiswa kwecalcium ilmenite mhando electrode kunogona zvakare kuwana zvinogutsa mhedzisiro.Kana simba welded majoini uye hwaro simbi haadi yakaenzana nguva inofanira kushandiswa yakaderera-simba inokosha yakaderera hydrogen electrodes.Yakadaro Weld Weld plastiki, inoburitsa kutonhora kutsemuka uye kupisa kwekuputika kwezvisina ngozi.

(2) Preheat iyo huru tekinoroji matanho ekushivirira uye kugadzirisa welding yekabhoni simbi, kunyanya kukora kweiyo weldment, kuomarara kwakakura, kudziya-mukuda kudzikisa kuoma kwakanyanya kwenzvimbo yakakanganisika uye kudzivirira kutonhora kutsemuka, uye kunogona kuvandudza. mapurasitiki akabatanidzwa.Pakazara kudziya-up uye kwakakodzera kudziya-up zvakare kunoderedza emuno post weld residual kusagadzikana.Iyo kabhoni yemukati yeakasiyana welding kabhoni simbi welding preheat tembiricha uye hapana yunifomu mitemo.Izvi hazvisi chete nekuti kusarudzwa kwekushisa kwekutanga kunotsanangurwa nekabhoni ye electrode, asi zvakare kukanganiswa nezvimwe zvinhu, senge saizi uye ukobvu hweweldment, welding mhando, iyo welding paramita uye kuoma kwechimiro uye. zvichingodaro.
