FLUX-CORED WELDING WIRE

Flux-Cored Welding Wire is an alkaline slag type CO2 gas shielded welding wire.
E700T5-K3
For welding 70OMPa grade high strength steel in all position
ACCORD WITH:GB/T17493-1998
CORRESPONDING TO:E7OOT5-D2
DESCRIPTION: E70OT5-K3 is an alkaline slag type CO2 gas shielded welding wire.The weld metal achieves a good mechanical properties by microalloying.lt can take the place of austanitic electrode to weld armor plate.
APPLICATIONS: Suitable for welding 15MnMoVN,14MnMoVB and the same grade low ally steel,such as tank, armor venicle,bulldozer and etc.
