Why use FCW M Mo?
-
Alloyed with Manganese and Molybdenum (M Mo) :
-
Manganese: improves the mechanical strength and ductility of the deposited metal.
-
Molybdenum: increases tensile strength, crack resistance and heat resistance, while maintaining good toughness.
-
-
Very good resistance to hot cracking: particularly useful for sensitive steels or multi-pass welding.
-
Excellent arc stability: even at high currents, which is crucial for high-speed automatic welding.
-
Excellent weld seam appearance: smooth, even, without excessive spatter.
-
Reduced smoke generation: compared to other cored wires, this improves working conditions, especially in robotized cabs.
-
Very good deposition rate: increases productivity compared with solid wire, with rapid melting and optimized penetration.
-
Versatile application: suitable for a wide range of low-alloy and non-alloy steels.
