Low Alloy Karfe Welding Electrode
Saukewa: J557SLA
GB/T E5515-G
AWS E8015-G
Bayani: Wannan ƙaramin hydrogen sodium da aka rufe shi da lantarki na musamman don ƙarfe alumini.Yi amfani da DCEP (tabbataccen lantarki na yanzu kai tsaye), kuma ana iya walda shi a duk wurare tare da gajeriyar aikin baka.J557SLA za a iya kai tsaye welded ba tare da cire aluminized Layer a kan tsagi surface kafin waldi.Amma J557SLB yakamata ya cire aluminized Layer a saman tsagi kafin waldawa.
Aikace-aikace: Ana amfani da walda da aluminized karfe tsarin a karkashin lalata matsakaici na hydrogen sulfide, sulfur, ammonia, ammonium bicarbonate da hydrogen nitrogen tare da aiki zafin jiki a kasa 540 ° C.Kamar bututun mai, kayan aikin tace mai, kayan aikin taki da bututun tururi da sauransu.

Sanarwa:
1. Dole ne a gasa wutar lantarki don 1 hour a kusa da 350 ℃ kafin aikin walda;
2. Yana da mahimmanci don tsaftace tsatsa, sikelin mai, ruwa, da ƙazanta akan sassan walda kafin walda.
