Flux-cored welding wire

Detailed Product Description

                                Flux-cored wire E70T-1( E71T-1)

 

 

Standard: AWS/A5.20 E70T-1  GB/T 10045 E500T-1

 

E70T-1 is a kind of Ti type flux-cored wire by CO₂.

 

It is superior to solid wires in cladding, welding technical performance and mechanical properties of deposited metal. It is used for the welding of low carbon steel and 490 grade strength steel of moderate thickness plates welding.

 

 It is widely used for flat welding and horizontal fillet welding, such as, ships, mechanical equipments and bridges.
