Hunhu uye Zvishandiso

TheweldmetalofE309/309Iine Cr Ni yakawanda kupfuuraE 308/308L.Iyo ine yakakodzera huwandu ferrite mu microstructure, inopa iyo yakanakisa kuramba kune inopisa kuputika.Yakagadzirirwa meta welding yakasiyana-siyana yekubatanidza simbi yakapfava kune simbi isina tsvina, inoomesa alloy simbi uye simbi isina kusimba.Prop base simbi dzinosanganisira Stainless simbi ndiro, simbi tambo, simbi chubhu, kupisa kutamisa chubhu, pressure vess simbi bhaa, kukandira uye forging.

Zvinyorwa zvekushandisa

1.Chenesa zvakasvibiswa pachigadziko chesimbi, groove uye pfuura kuti upfuure nesimbi isina tsvina.
2.Kuchengetedza pfupi arclength inogoneka inokurudzirwa zvikuru.Nepo welding ne weave method, mov range inofanirwa kudzorwa mukati me2.5 times yewaya's dia.
3. Pukuta ma electrodes pa250 ~ 300 ℃ kwemaminitsi makumi matanhatu usati washandisa.Bvisa zvinodyiwa zvehaif zuva rekushandisa uye chengeta munzvimbo iri pa 100 ~ 150 ℃ panguva yewelding process.
4. Shandisa yakaderera ikozvino kudzivirira kubva kuputika uye kuderedza base metal dilution.

Tsanangudzo

Mhando dzeElectrodes	Nhanganyaya	Uses
Muenzaniso: CB-J421 GB: E4313 AWS: E6013	Iyo imhando yekabhoni simbi electrode ine titania rudzi rwekupfeka. AC/DC. Yese chinzvimbo welding. Iyo ine yakanakisa welding performance, kushanda kwakanaka kwazvo, kutonga kuri nyore, arc yakagadzikana, kutaridzika kwakanaka kwe weld.	Kukuchidzira yakaderera kabhoni simbi zvimiro, kunyanya akakodzera welding pamahwendefa matete uye cometic welding izvo zvinoda weld beads kuva akanaka uye kupenya.
Muenzaniso: CB-J425 GB: E4311 AWS: E6011	Iyo imhando yekabhoni simbi electrode ine cellulose potassium mhando coating. AC/DC. Iyo ine yakanakisa welding performance, inoyevedza kutaridzika mushure mekudzika yakadzika welding, mashoma slags uye yakakwirira welding kunyatsoita.	Inokodzera kubatira butt welding, fillet welding uye lap welding pamahwendefa matete, senge yakaderera kabhoni simbi zvimiro senge flue emagetsi zviteshi, madhiraivha emhepo, etransformer mafuta matangi, hulls, ekunze mapaneru emota, nezvimwe.
Muenzaniso: CB-J508 GB: E5018 AWS: E7018	Iyo imhando yekabhoni simbi electrode ine yakaderera hydrogen mhando yekubatisa. AC/DC. Iyo ine yakanakisa welding performance, nyore kutonga, yakagadzikana arc, yakanaka kutaridzika kwe weld.	Inoshandiswa kugadzira kabhoni simbi uye yakaderera alloy simbi zvimiro, senge 16Mn, nezvimwe.
