Babban Shawarar Azurfa na tushen Brazing Manna
Azurfa Base Brazing Manna Aikace-aikacen
Azurfa brazing tsari ne na haɗawa wanda ba ƙarfe mai cike da ƙarfe ba, gami da dumama ga zafin narke (sama da 800°F) kuma ana rarrabawa tsakanin sassa biyu ko fiye da ke kusa ta hanyar jan hankali.
Babban abubuwan da aka haɗa da manna brazing na azurfa sun haɗa da foda na azurfa, wakili na walda da ƙarin taimako.Azurfa foda wani mahimmin sashi ne wanda ke samar da wutar lantarki da yanayin zafi, wanda ke iya cika ɓangarorin guraben daɗaɗɗa da narke a matsanancin zafi.Ana amfani da wakili na walda don tsaftacewa da cire shingen oxide da inganta haɗin haɗin abubuwan brazed.Matsayin ƙari shine haɓaka ingancin walda, rage iskar shaka da haɓaka ƙarfi da amincin haɗin haɗin gwiwa.
Ana amfani da azurfa, azurfa da tagulla da tagulla;Low carbon karfe, low gami karfe, bakin karfe, high zafin jiki nickel tushe gami, refractory karfe da kowane irin lantarki lamba kayan brazing.
