Pakusanganisa simbi isingatsvi, kusarudza maerekitirodhi kwakakosha kuti uwane weld yemhando yepamusoro uye inogara kwenguva refu. Apa ndipo panodiwaAF2209-15 (AWS E2209-15)Inouya. Iyi electrode yesimbi isina ngura ine nitrogen shoma ine kabhoni yakawanda yakagadzirirwa kusangana nezvinodiwa zvakanyanya zvekunamira. Nekupfeka kwayo kwehydrogen shoma, AF2209-15 inoita kuti kunamira kuve kwakanaka uye kushanda zvakanaka.
AF2209-15 yakagadzirirwa kusanganisa simbi dzisina ngura mbiri uye inopa simba rakanaka rekudzivirira ngura uye simba rayo guru. Kabhoni yayo yakaderera zvikuru inoderedza njodzi yekunaya kwemvura mu carbide, ichivimbisa hunhu hwakanaka hwemakanika uye kugona kusanganisa. Nitrogen yakawanda inowedzerawo kuramba kwe weld kugomba uye ngura, zvichiita kuti AF2209-15 ive yakakodzera kushandiswa kwakakosha mumaindasitiri akadai semafuta negesi, kugadzira makemikari uye mainjiniya ekunze.
Chimwe chezvinhu zvakakosha zveAF2209-15 ipurasitiki yayo isina hydrogen yakawanda, iyo inoderedza zvakanyanya njodzi yekutsemuka kunokonzerwa nehydrogen. Izvi zvinoita kuti ive yakakodzera kushandiswa kwewelding uko hydrogen embrittlement iri nyaya, zvichiita kuti weld irambe yakasimba uye kwenguva refu. Electrode ine arc yakagadzikana uye hunhu hwewelding hwakatsetseka zvinowedzera kubatsira mukushandiswa kwayo nyore uye kushanda kwayo nguva dzose, zvichikonzera kushanda kwayo zvakanaka uye kwakavimbika kwewelding.
Pamusoro pekushanda zvakanaka kwazvo kwewelding, AF2209-15 yakagadzirwa nepfungwa yekushanda nesimba uye nyore. Ingave ichishandiswa panzvimbo dzakati sandara, dzakatwasuka, dzakamira kana pamusoro, electrode iyi inopa welds dzakafanana uye dzemhando yepamusoro. Yakakodzera zvinhu zvakasiyana-siyana zvepasi, zvinosanganisira UNS S31803, S32205 uye S2205 duplex stainless steels, zvichiita kuti ive mhinduro inoshanda zvakanyanya kune akasiyana-siyana mashandisirwo ewelding.
Pakazara, AF2209-15 inoisa mwero mutsva wemaelectrode esimbi isina ngura, ichipa mashandiro asina kujairika, kuvimbika uye kushanduka-shanduka. Electrode iyi ine nitrogen shoma ine kabhoni, hydrogen coating yakaderera uye inodzivirira ngura zvakanyanya, ndiyo sarudzo yepamusoro yemhando yepamusoro yeweld uye kugara kwenguva refu. Kunyangwe uri kushanda pamapurojekiti akakosha ezvivakwa kana mashandisirwo einjiniya chaiyo, AF2209-15 ndiyo mhinduro inosarudzwa pamatambudziko akaomarara ewelding.
