Bakin Karfe Walda Electrode
A402
GB/T E310-16
AWS A5.4 E310-16
Bayani: A402 wani electrode ne mai tsabta na Cr26Ni21 mai launin austenitic mai rufin calcium na titanium. Ana iya amfani da shi don AC da DC tare da kyakkyawan aikin aiki. Karfe da aka ajiye yana da kyakkyawan juriya ga iskar shaka a ƙarƙashin yanayin zafi mai zafi na 900 ~ 1100 ℃.
Aikace-aikace: Ana amfani da shi don walda irin wannan nau'in bakin ƙarfe mai jure zafi wanda ke aiki a ƙarƙashin yanayin zafi mai yawa, kuma ana iya amfani da shi don walda na ƙarfe chromium masu tauri (kamar Cr5Mo, Cr9Mo, Cr13 da Cr28, da sauransu) da ƙarfe daban-daban.

Sanarwa:
- Dole ne a gasa wutar lantarki na tsawon awa 1 a kusan 250℃ kafin aikin walda;
- Saboda zurfin shigar ciki ba shi da zurfi yayin walda ta AC, ya kamata a yi amfani da wutar lantarki ta DC gwargwadon iyawa don samun zurfin shigar ciki. Kuma kada wutar ta yi girma sosai don guje wa jajayen sandar walda.
An kafa kamfanin Wenzhou Tianyu Electronic Co., Ltd. a shekara ta 2000. Mun shafe sama da shekaru 20 muna kera na'urorin lantarki na walda, sandunan walda, da kuma kayan da ake amfani da su wajen walda.
