APPLICATIONS:
Yakakodzera kukwenenzverwa kwesimbi yakasimba grey uye nodular cast iron, senge silinda, injini block, giya bhokisi, nezvimwewo.
CLASSIFICATIONS:
AWS A5.15 / ASME SFA5.15 ENiFe-CI
JIS Z3252 DFCNiFe
ZVINHU:
AWS ENiFe-CI (Z408) ndiyo yakakandwa simbi electrode ine nickel iron alloy core uye kudzika kwakasimba kwegraphite coating.Inogona kushandiswa mu AC uye DC mbiri chinangwa, ine yakagadzikana arc, uye iri nyore kushanda.Iyo electrode ine hunhu hwekusimba kwepamusoro, yakanaka plasticity, yakaderera mutsara wekuwedzera coefficient uye zvichingodaro.Kutsemuka kwesimbi yegrey cast iron kwakafanana neiyo yeZ308, ukuwo kutsemuka kwenodular cast iron kunodarika ENi-CI (Z308).Kune simbi yakakandwa ine yakakwira phosphorus (0.2% P), ine zvakare mhedzisiro yakanaka uye yayo yekucheka kuita yakaderera pane Z308 uye Z508 zvishoma.Z408 inoshandiswa mukunama simbi yegrey uye nodular cast iron yekamuri
TARIRA:
Asati apinza, maelectrodes anoda kubikwa kweawa imwe chete nekudziya kwe150±10℃ asati ashandisa.
Kana welding, zvakakodzera kutora nhete weld uye kureba kwega kwega hakufanire kudarika 50mm.Hammer nzvimbo yewelding zvishoma nenyundo pakarepo mushure mekugadzirisa kuitira kubvisa kushushikana uye kudzivirira kuputika.
Lower heat input inokurudzirwa.

Hunhu pakushandisa:
Yakanyanya kugadzikana arc.
Yakanakisa kubviswa kwe slag.
Kupinda hakuna kudzika.
Kupisa kwakanaka uye kusagadzikana kwekuora.
Excellent crack resistance.
