Bakin Karfe Welding Electrode
A302
GB/T E309-16
AWS A5.4 E309-16
Bayani: A302 shine Cr23Ni13 bakin karfe na lantarki tare da shafi titanium-calcium.Ana iya amfani dashi don duka AC da DC tare da kyakkyawan aikin aiki.Ƙarfin da aka ajiye yana da juriya mai girma da juriya na iskar shaka.
Aikace-aikacen: Ana amfani da shi don walda irin nau'in bakin karfe, rufin bakin karfe, karfe na musamman (Cr19Ni9 daidai yake da ƙananan ƙarfe na carbon), babban karfe na chromium, babban manganese karfe, da dai sauransu.
Abubuwan sinadaran na weld karfe(%):

Shawarwari na yanzu:
| Diamita na sanda (mm) da | 2.5 | 3.2 | 4.0 | 5.0 |
| Welding Current (A) | 50 ~ 80 | 80 ~ 110 | 110 ~ 160 | 160 ~ 200 |
Sanarwa:
1. Dole ne a gasa wutar lantarki don 1 hour a 150 ℃ kafin aikin walda;
2. Saboda zurfin shigar ciki ba shi da zurfi a lokacin waldi na AC, ya kamata a yi amfani da wutar lantarki ta DC gwargwadon yadda zai yiwu don samun zurfin shigar ciki.kuma kada na yanzu ya zama babba don gujewa jajayen sandar walda.
