E6020 Welding Rod ISO E4320A(CHE424)
It is suitable for welding structures fabricated by medium plates or thick plates of mild steel, heavy machinery and construction machinery. Its melting rate is fast and penetration is deep. The weld metal has good crack resistance.
Type of Covering: High iron oxide
Welding Position: F, HF
Type of Current: AC, DCEP or DCEN
Notice: Normally the rod does not need to re-dry in case it is affected with damp seriously re-baked it at 150℃ for 30-60 minutes before use.
