Pakusanganisa simbi dzinopisa zvishoma, kusarudza electrode yakakodzera kwakakosha kuti uwane welds dzemhando yepamusoro uye dzinogara kwenguva refu. W107 (AWS E7015-C2L) ielectrode inoonekwa pamusika.electrode yesimbi ine tembiricha yakadereraYakagadzirwa ne hydrogen sodium coating shoma, zvichiita kuti ive yakakodzera kushandiswa pakusonta munzvimbo dzine tembiricha yakaderera. Inokwanisa kuchengetedza kusimba kwakanaka kusvika -100°C, W107 electrode mhinduro yakavimbika kumapurojekiti ekusonta anoda kushanda zvakanaka mumamiriro ekunze anotonhora zvakanyanya.
Tsvimbo yekuwelda yeW107 yakagadzirwa zvakanyanya pakuwelda simbi ine tembiricha yakaderera uye inopa mhedzisiro yakanaka mukusimba uye kugara kwenguva refu. Kuvhara kwayo sodium shoma yehydrogen kunoita kuti hydrogen isanyanye kunyudzwa panguva yekuwelda, izvo zvakakosha kudzivirira kutsemuka uye kuve nechokwadi chekuti weld yacho haina kutsemuka. Izvi zvinoita kuti ive sarudzo yekutanga yekuwelda zvivakwa zvakakosha uye zvikamu zvinosangana netembiricha yakaderera, zvakaita sematangi e cryogenic, mapaipi nemidziyo inoshandiswa munzvimbo dzinotonhora.
Chimwe chezvinhu zvikuru zveW107 electrode ndechekuti inogona kushandiswa munzvimbo dzakasiyana-siyana dzekuwelda. Ingava yakatwasuka, yakatwasuka, yepamusoro kana kuti yakatsetseka, electrode iyi inogona kushandiswa munzvimbo dzese, zvichipa vanowelda mukana wekuchinjika uye nyore kushanda pamapurojekiti akasiyana-siyana. Pamusoro pezvo, electrode iyi yakagadzirirwa kushandiswa neDC Positive Electrode (DCEp) kuti iwane kushanda kwakanaka uye kwakasimba kwewelda mumashandisirwo akasiyana-siyana ekuwelda.
Simbi yakachengetwa yeW107 electrode inochengetedza kusimba kwakanaka kwesimba kunyangwe pakupisa kwakaderera zvakanyanya, zvichiita kuti ive sarudzo yakavimbika yekushandisa kana weld iri mumamiriro ekunze ekutonhora kwakanyanya. Kusimba uku kunoshamisa kunoita kuti weld irambe yakasimba uye ichishanda zvakanaka kunyangwe munzvimbo dziri pasi pe zero, zvichipa kuvimbika kwenguva refu uye kuchengetedzeka kune zvikamu zvakasungirirwa.
Muchidimbu, W107 (AWS E7015-C2L) Low Temperature Steel Welding Rod ndiyo mhinduro yepamusoro yekushandisa welding inoda kushanda kwepamusoro munzvimbo dzine tembiricha yakaderera. Kuvhara kwayo hydrogen sodium shoma pamwe nekugona kwayo kuchengetedza kusimba kwakanaka pa -100°C kunoita kuti ive sarudzo yakanaka kune vanowelders vari kutsvaga mhedzisiro yepamusoro uye yakavimbika mumamiriro ekunze anotonhora zvakanyanya. Nekugona kwayo kuchinjika uye kuenderana neDCEP, W107 electrode inopa vanowelders chivimbo uye vimbiso yavanoda kuti vagadzirise mapurojekiti ewelding esimbi ane tembiricha yakaderera neunyanzvi uye neunyanzvi.
