Castings & Rotating Equipment Weld Repair
Titanium Fabrication Corporation (TiFab) is a leading provider of titanium weld casting repair services, offering unmatched expertise in restoring and enhancing titanium and zirconium components for demanding industries. From high-value castings used in naval propulsion systems to mission-critical rotating equipment in chemical processing plants, TiFab delivers precision weld repairs that meet NAVSEA and ASME code requirements.
Few fabrication shops in North America possess the experience, certifications, and metallurgical knowledge to successfully weld repair titanium and zirconium castings and rotating assemblies. TiFab stands at the top of that list.
Industry-Leading Repair Services for Titanium and Zirconium Components
TiFab has developed specialized capabilities to repair corrosion-resistant titanium and zirconium castings that suffer from pitting, cracks, or structural wear. These castings are commonly used in:
- Pumps and impellers
- Valve bodies and bonnets
- Vessel components
- Housing and flange assemblies
- Rotating equipment for marine, chemical, and energy systems
Most OEMs and end users do not have in-house resources to perform weld repairs on titanium castings or rotating equipment. TiFab fills this gap with a full suite of repair solutions performed in-house by certified welders and metallurgists.
Comprehensive Titanium Rotating Equipment Weld Repair Services
Rotating equipment fabricated from titanium or zirconium presents unique challenges in the field of maintenance and lifecycle management. TiFab's titanium rotating equipment weld repair services address those challenges with expertise that includes:
- Excavating and weld-filling pitted areas
- Repairing surface and through-wall cracks
- Restoring worn flange faces and bearing seats to dimensional tolerances
- Rebuilding geometry through weld buildup and precision machining
- Non-destructive testing to validate final integrity
Our repair teams work closely with OEMs and operators in sectors such as shipbuilding, aerospace, and energy to restore equipment performance and extend service life.
Certified to NAVSEA and ASME Standards
TiFab is fully qualified to perform titanium and zirconium weld repairs under both military and industrial specifications. We maintain approved welding procedures and testing protocols in accordance with:
- NAVSEA S9074-AQ-GIB-010/248 (MIL-STD-248) – Welding and brazing procedure and performance qualification
- NAVSEA S9074-AR-GIB-010/278 (MIL-STD-278) – Fabrication, welding, and casting inspection for machinery and pressure vessels
- NAVSEA T9074-AS-GIB-010/271 (MIL-STD-271) – Nondestructive testing standards
- ASME Section IX – Welding procedure and performance qualification for code work
These certifications are backed by decades of experience supporting the U.S. Navy, defense contractors, and industrial clients requiring strict quality assurance.
Welding Processes Supported
TiFab applies multiple advanced welding methods, depending on component geometry, alloy composition, and repair objectives. Our capabilities include:
GTAW (TIG – Gas Tungsten Arc Welding)
The preferred process for titanium and zirconium weld repairs due to its precision and control in reactive metal environments.
GMAW (MIG – Gas Metal Arc Welding)
Used for select weld build-up applications on large-diameter or thicker sections.
PAW (Plasma Arc Welding)
Ideal for high-precision welds requiring deeper penetration and automated control.
SAW (Submerged Arc Welding)
Deployed on large, fabricated components where high deposition rates and deep fusion are needed.
From Castings to Fabricated Alternatives
In some cases, TiFab is able to replace legacy titanium castings with fabricated and machined weldments that deliver improved lead times, cost savings, and performance consistency. For certain geometries and service conditions, fabricated solutions offer better control over metallurgical properties and dimensional tolerances. Our engineering team can evaluate your component and provide a recommendation tailored to your application.
