113044G452 - Josef OW220 .045 Build-Up Flux Core Wire - 25lb Spool

Industrial Grade Dimensional Restoration Wire

For professional welders and fabricators tasked with equipment repair, the Josef OW220 .045 Build-Up Flux Core Wire delivers the performance needed to tackle severe wear. This wire is formulated to rebuild carbon and low-alloy steel parts that have been worn down to undersize conditions. It serves as the perfect "butter pass" or build-up layer, providing a sound metallurgical base for subsequent hardfacing layers.

The .045-inch diameter is versatile for a wide range of positional welding and deposition rates. As a flux-cored wire, it offers deep penetration and good sidewall fusion, minimizing the risk of lack-of-fusion defects which can be catastrophic in high-stress components. The slag system is designed to support the puddle while being easy to remove, reducing cleanup time between passes. The 11.36kg spool size fits standard industrial wire feeders, ensuring you have enough material for substantial repair jobs without frequent changeovers.

One of the standout characteristics of this wire is its deposit properties. It creates a weld metal that is neither too soft to deform nor too hard to crack. This balance is essential for parts like crane wheels, idlers, and mine car wheels, which are subjected to constant rolling loads. The deposit typically hardens to a range that is machinable with carbide tools, allowing you to turn or mill the part back to OEM specifications.

Using the correct build-up wire is critical; using a standard mild steel wire may not offer the compressive strength needed, while using hardfacing wire for buildup can lead to check cracking and failure. The Josef OW220 eliminates this guesswork, providing a specialized solution optimized for rebuilding geometry. It is an essential inventory item for any MRO shop dealing with earthmoving equipment, crushers, or heavy industrial machinery.
