FCW B NiMo
Description & applications
• Seamless high fill copper coated basic cored tubular wire for semi-automatic gas shielded arc welding
• For single and multiple pass welding of cold tough / fine-grained steels
• Optimal productivity by combining advantages of both seamless and seamed tubular wires
• HDM guaranteed < 4 ml/ 100g deposited metal on the whole parameter box
• No moisture pick up, excellent wire feeding properties, good weldability and low spatter
• Exceptional mechanical properties
