Description: It is a seamless rutile flux cored wire which contains 2% Ni;Due to its seamless characteristic, the wire has an extremely low hydrogen content (typical 3ml/100g weld metal), which can effectively reduce the risk of hydrogen-induced cracks； It has a stable welding arc with less spatter and perfect bead surface,it also has excellent weldability.
Application: Welding for port machinery, bridges, such as HY-100, A514 high strength steel.
