ITW Megafil cored wires
Gas shielded flux cored wires were developed mainly for welding structural steels and thick materials. They offer higher process reliability than solid wires, have a higher deposition rate and can be used in constrained positions. All of these advantages result in a higher production rate than solid wire or electric hand welding with fewer defects in the weld.
Production
The unique production technology ITW Welding uses to produce MEGAFIL® seamless flux cored wire provides valuable product benefits to the end user. The manufacturing process is divided as follows: Strip is formed into a tube, HF welded and then drawn to the filling diameter. In the next step, the tube is filled with agglomerated powder by means of a vibration system. Then the wire is annealed, drawn to the final diameter and coated with copper. Finally, the wire is precisely wound onto different spool sizes in layers. The result is a completely closed flux cored wire with an extremely dry powder core that does not absorb any moisture during storage and welding.
Approvals
MEGAFIL® seamless cored wires are available for most steel grades with a wide range of approvals from societies such as ABS, DNV, LR and TÜV. The wire can be ordered with a 3.1 certificate that lists the real values of chemical composition and mechanical properties of the delivered batch.
Brands from ITW
We can offer you not only filler wires from ITW, but also welding consumables from Hobart and Elga.
All advantages at a glance
-
Higher deposition rate due to increased welding parameters
-
Higher process reliability, can be used in constrained positions and produces fewer defects in the weld seam
-
Prevention of hydrogen-induced cracking . The hydrogen content in the weld metal, tested according to EN and AWS, is below 4 ml/100 g Typical values are below 3 ml/100 g
-
Special precautions for storage are not necessary. Can be stored indefinitely like solid wire. No risk of moisture absorption
-
No need for re-drying, even after storage in a humid environment
-
Resistant to moisture absorption even after removal from the package, e.g. when mounted on wire feed unit
-
No voids in the filling – thus reliable weld metal properties
-
Copper coating for optimum welding current transfer between contact tip and wire and to minimize contact tip wear
-
Excellent wire feeding characteristics and twist-free entry into the contact tip due to carefully controlled dimensions, cast and helix. Ideal for robot welding
