OVERVIEW

Restore Worn Parts with Confidence

When heavy equipment wears down, replacing parts isn't always the most cost-effective option. The Hobart Tube-Alloy Buildup-G .045" wire is your go-to solution for bringing worn steel components back to life. Designed for professional welders in maintenance and repair operations (MRO), this wire excels at rebuilding dimension on parts that have been subjected to metal-to-metal wear. Whether you are repairing crane wheels, dragline buckets, or coupling boxes, this wire provides the tough, impact-resistant foundation necessary for a long-lasting repair.

The Perfect Base for Hardfacing

Think of Tube-Alloy Buildup-G as the shock absorber for your hardfacing job. If you apply a super-hard, abrasion-resistant alloy directly onto a soft or worn base, heavy impacts can cause the hard layer to crack or peel off. By first building up the part with Tube-Alloy Buildup-G, you create a rigid, high-compressive-strength underlayment that supports the brittle top layer. This extends the service life of your equipment significantly compared to using standard mild steel wire for buildup.

User-Friendly Performance

Welders will appreciate the smooth runnability of this metal-cored wire. Because it is gas-shielded (typically 75/25 Ar/CO2), it offers a stable arc, minimal spatter, and very little slag to clean up between passes. This efficiency allows you to stack multiple layers quickly and cleanly. Additionally, if the part needs to be machined back to a specific tolerance, the deposit is fully machinable with standard carbide tools, making it versatile for a wide range of shop repairs. Don't just patch it—rebuild it stronger with Hobart Tube-Alloy.

FAQ

This wire typically requires a mixture of 75% Argon and 25% CO2. It can also run on other mixtures like 98% Argon / 2% Oxygen depending on the specific procedure, but 75/25 is the standard recommendation for optimal arc stability and penetration.

Yes, the deposit from Tube-Alloy Buildup-G is machinable with carbide tools. This makes it excellent for applications like crane wheels or shafts where the part must be returned to specific dimensions after welding.

While it has good strength, it is primarily designed for buildup and surfacing applications on mild and low alloy steels, not for structural joining of cracks. For joining, a specific joining wire (like E71T-1) is usually recommended.

The typical hardness is approximately 25-30 HRC (Rockwell C) or 250-300 HB (Brinell). This provides toughness and compressive strength rather than extreme abrasion resistance.

Yes, Tube-Alloy Buildup-G is designed for unlimited deposit thickness. You can apply as many layers as needed to restore the part to its original size.

This wire is designed to operate on Direct Current Electrode Positive (DCEP).

Standard MIG wire (like ER70S-6) is softer and has less compressive strength. Tube-Alloy Buildup-G is alloyed to provide a stronger, more rigid base that won't deform under heavy loads, preventing the hardfacing layer on top from failing.

This is a metal-cored wire. It contains metallic powders in the core and requires an external shielding gas. It offers higher deposition rates than solid wire and less slag than traditional flux-cored wires.
