Description: It is a seamless rutile flux cored wire which contains 2% Ni;Due to the seamless design ,the wire has an extremely low hydrogen content which is very important when welding extra high tensile steels;It has a stable welding arc with less spatter and perfect bead surface,it also has excellent weldability;.
Application: Welding for the same strength leave structures of bridge, port machinery,suchas:HY-100,A514,Q690.
