BW70S-4 is a GTAW wire.
BW70S-4 is a copper coated, double de-oxidised low carbon steel filler rod suitable for
the oxy-acetylene (fusion) welding and Gas Tungsten Arc (TIG) welding of a wide range of mild and medium strength steels.
BW70S-4 is recommended for the TIG welding of steel pipes, plates and castings with a
tensile strength in the 500 MPa class. It is tolerant to surface rust and mill scale and is ideal for root pass welding applications where tough and ductile welds are produced.
