1128404525 - Josef OW284 .045 Build-Up Flux Core Wire 25lb Spool

High-Performance .045" Flux Core Build-Up Wire

Welders and fabricators looking for a dependable solution to restore worn parts will find the Josef OW284 .045" Build-Up Wire to be an essential addition to their inventory. This flux-cored wire is engineered to deposit a low-alloy steel layer that restores the original dimensions of worn components. Unlike hardfacing wires which are often too hard to machine, the OW284 deposit is fully machinable, allowing you to turn shafts and rollers back to their precise tolerances after welding.

Key Technical Benefits:

• Machinability: The weld deposit has a moderate hardness that allows for shaping and finishing with standard tooling, making it perfect for shafts, trunnions, and gear teeth.
• Compressive Strength: It provides a rigid, non-deforming base that supports subsequent layers of hardfacing. Without a proper build-up layer, hardfacing on a soft base metal can collapse under high loads.
• Crack Resistance: The alloy is designed to resist cracking, even in multi-pass applications, ensuring structural integrity.

This 11.36kg (approx. 25 lbs) spool is designed for use with standard wire feeders. It operates with excellent arc stability and slag release, reducing cleanup time between passes. It is suitable for use on carbon steels and low-alloy steels commonly found in heavy equipment. Whether used as a final surface for metal-to-metal wear or as an underbase for high-impact hardfacing, the Josef OW284 ensures a quality repair that extends the service life of your equipment.
