MEGAFIL®: Seamless Cored Wires Production Technology

The unique production technology ITW Welding utilizes to manufacture MEGAFIL® seamless flux- and metal-cored wires results in valuable product benefits for end users. Strips are folded round, closed by high frequency welding and drawn to filling diameter.

In the next step, the tube is filled with agglomerated flux by means of a vibration system. In several steps the wire is annealed, drawn to final diameter and finally copper-coated.

Subsequently, the wire is precision layer-wound onto various spool sizes. The result is a full penetration closed cored wire with an extremely dry flux core, which is totally insensitive for moisture reabsorption during storage and use.
