Weldingelectrode ine zvikamu zviviri, core uye coating.Metal core welding electrodes iri kunze kwependi (coating) yunifomu kumanikidzwa inoiswa kune yakanyatso solder core.Mhando dzakasiyana dzewelding, welding core dzakasiyana.Welding electrode core metal core, kuitira kuve nechokwadi chemhando uye kushanda kweweld, butt iyo yepakati yemukati yesimbi element ine mitemo yakasimba, kunyanya kune zviri mukati metsvina inokuvadza (senge sarufa, phosphorus, nezvimwewo), panofanira. ivai zvirambidzo zvakasimba kupfuura zvinhu zvehwaro.Electrode mushonga bhegi yainzi weld metal core coated core.Welding core waya kazhinji ine humwe hurefu uye dhayamita.Kana soldering, welding core ine maitiro maviri: Chekutanga, kuitisa welding ikozvino, iyo arc simba inoshandurwa kuita kupisa, yechipiri musimboti waya pachayo inoshandiswa sesimbi yekuzadza ine mvura yakanyungudutswa mubereki simbi fusion weld inoumbwa.

Dzvinyiriro inoiswa pamusoro peiyo coating inonzi core solder coating.Electrode coating inoita basa rakakosha zvakanyanya mukuita welding.Iko kushandiswa kwemagetsi-isina mwenje ganda electrode welding, iyo welding process, iyo okisijeni uye nitrogen mumhepo ichave yakanyanya kupinda mukati mesimbi yakanyungudutswa, iyo simbi yesimbi uye inobatsira zvinhu kabhoni, silicon, manganese oxide uye nitride kuumbwa kweakasiyana oxides uye. nitrides, uye inoramba iri mu weld, weld slag, kana kukonzera kutsemuka.Kunyunguduka kwegasi kunogona kukonzera kuwanda kwe weld porosity, zvinhu izvi zvinogona kuita kuti michina ye weld (simba, kukosha kwekukanganisa, nezvimwewo) ideredzwe zvakanyanya, nepo weld brittle.

SMAW welding electrodes anoshandiswa nekukoira uye welding core inoumbwa nezvikamu zviviri.Kana welding, a welding electrode soruoko rumwe, uye kubva mutyairi arc ikozvino conduction mugumisiro, kuti pakati electrodes uye hwaro simbi mune inopfuurira, yakatsiga arc, kupa kupisa zvakakodzera kunyungudutsa solder.Kune rumwe rutivi, uye sesimbi inoputika yekuzadza yakawedzerwa kune weld kuti ive chikamu chikuru chesimbi ye weld.Saizvozvo, kuumbwa kwemhando yewelding uye welding, iyo kemikari yeweld simbi inokanganisa zvakananga ma mechanic properties uye yemuviri zvinhu.Uyezve, iyo electrode inewo simba guru pakugadzikana kwekutaridzika kwemhando ye weld, iyo welding process senge welding kugadzirwa.
