FCW M Ni3
Description & applications
• Seamless cored copper coated tubular wire for gas shielded flux cored arc welding
• Designed for welding 3.5 % Ni steel with impact requirements down to -101°C
• 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
APPLICATIONS
Tough at subzero steels
