Product Application
Titanium anodes are widely used in cathodic protection systems to prevent corrosion of metal structures. Here’s how they function in various applications:
1.Protection of Water Heater Storage Tanks
Titanium anodes are installed inside water heater tanks to protect the inner surfaces from corrosion.
They act as sacrificial anodes, corroding in place of the tank material (usually steel), thereby extending the lifespan of the tank.
The anodes are often coated with mixed metal oxides (MMO) to enhance their efficiency and durability in high-temperature and aggressive water environments.
2. Hull, Pipeline, Platform, Dock, Dam, and Power Station Cooling Water System Inlets
In marine environments, titanium anodes are used to protect submerged structures such as ship hulls, offshore platforms, and docks.
They are connected to an impressed current cathodic protection (ICCP) system, where an external power source drives the anodes to release current, counteracting the corrosion process on the metal surfaces.
The anodes are particularly effective in seawater due to their high conductivity and resistance to chloride-induced corrosion.
3. Internal Protection of Oil Storage Tanks, Condensers, Pipelines, and Heat Exchangers
Inside oil storage tanks and pipelines, titanium anodes are used to protect against internal corrosion caused by aggressive fluids or gases.
In condensers and heat exchangers, the anodes prevent corrosion of metal surfaces exposed to cooling water or other corrosive media.
The anodes are often pre-packaged with conductive materials like coke breeze to ensure uniform current distribution and maximize protection.
4. Metal Protection for Buried Structures (Carbon-Containing Soil)
For buried structures such as pipelines or storage tanks, titanium anodes are installed in anode beds (shallow or deep) to provide cathodic protection.
The anodes are connected to an impressed current system, which generates a protective current that flows through the soil to the metal structure, preventing corrosion.
Titanium anodes are preferred in carbon-containing soils due to their high durability and resistance to chemical degradation.
Key Advantages of Titanium Anodes in Cathodic Protection:
In titanium cutting processes, preventing material damage and minimizing heat-affected zones (HAZ) are crucial for ensuring product quality. Below are some common issues encountered during cutting and their corresponding solutions:
High Corrosion Resistance: Titanium’s natural oxide layer makes it highly resistant to corrosion, even in aggressive environments.
Long Lifespan: Titanium anodes, especially those coated with MMO, have a significantly longer lifespan compared to traditional sacrificial anodes.
Efficiency: They provide consistent and reliable current output, ensuring effective protection over large areas.
Versatility: Titanium anodes can be customized in various shapes and sizes to suit specific applications, from small water heaters to large marine structures.
Select Appropriate Cutting Methods: Use non-thermal methods such as waterjet cutting or wire EDM to avoid HAZ.
Optimize Cutting Parameters: Lower cutting power and increase speed to reduce heat concentration.
Use Cooling Techniques: Introduce water or air cooling during cutting to lower surface temperatures.
Surface Protection Treatments: Apply anti-oxidation coatings before cutting to mitigate high-temperature oxidation.
Principles of cathodic protection
Through external intervention, the entire metal surface becomes a cathode, eliminating the anodic zone and thus inhibiting the oxidative dissolution of the metal itself.

Welding is a critical step in titanium anode manufacturing, directly influencing product performance, durability, and cost. Choosing the right welding method depends on factors such as the sequence of production processes, potential thermal impacts from repeated sintering, and the desired balance between quality and price. Below, we explore these aspects to help purchasers make informed decisions.
1. Key Factors Affecting Quality and Cost
Impact on Quality:
- Weld Strength: Ensuring robust welds is essential to prevent detachment or leakage in harsh electrolytic environments.
- Thermal Stability: Repeated sintering during coating processes can cause weld deformation, potentially compromising product performance.
- Surface Finish: Smooth, defect-free weld seams are crucial for even coating application.
Impact on Cost:
- Welding Complexity: Advanced methods like electron beam welding (EBW) are precise but costly, while TIG welding offers a cost-effective alternative for simpler designs.
- Post-Weld Treatments: Processes like polishing or additional testing increase overall costs but enhance quality.
- Process Sequence: Welding before or after coating affects the need for additional protections, influencing total expenses.
2. Choosing the Right Welding Method
Before or After Coating?
- Before Coating: Preferred for processes involving repeated sintering, as the coating layers are not exposed to thermal stress during welding. However, this requires welds to endure subsequent high-temperature sintering.
- After Coating: Suitable for products where precise coating coverage is critical, but special care must be taken to prevent welds from damaging the coating.
3. Comparative Overview of Welding Methods
| Welding Method | Impact on Quality | Impact on Cost | Best Applied |
|---|---|---|---|
| TIG Welding | High precision and strong welds; moderate thermal stress. | Low to Moderate | Thin components or standard designs. |
| Plasma Arc Welding (PAW) | Excellent for thicker materials; high weld stability. | Moderate to High | Large or complex structures. |
| Electron Beam Welding (EBW) | Extremely precise; minimal distortion but requires vacuum environment. | High | High-end, ultra-precise applications. |
| Laser Beam Welding (LBW) | High precision and speed; moderate thermal stress. | High | Mass production with tight tolerances. |
| Resistance Welding | Limited to certain joint types; may leave marks. | Low | Simple joints with lower strength needs. |
4. Recommendations for Titanium Anode Purchasers
Evaluate Product Requirements:
- For products undergoing repeated sintering, prioritize welding methods that minimize thermal deformation (e.g., EBW or PAW).
- For designs requiring uniform coating, ensure weld seams are smooth and defect-free.
Consider Production Sequence:
- If welding is performed before coating, use high-temperature-resistant methods to maintain weld integrity.
- If welding is done after coating, ensure that protective measures are in place to prevent coating damage.
Balance Quality and Cost:
- For premium-quality products, advanced methods like EBW or LBW ensure the highest precision.
- For standard applications, TIG welding offers a cost-effective solution without compromising reliability.

How to Simplify Your Titanium Anode Production Challenges?
In titanium anode production, precise cutting and welding processes are essential. They directly impact product performance and cost control. We understand the challenges you face, such as maintaining strict angle tolerances during sintering, ensuring consistent welding quality, and balancing production costs. Here’s how we provide tailored solutions to simplify these complex issues and make collaboration more efficient:
1. Precision-Based Recommendations
Cutting and Welding Process Selection:
Our team analyzes your specific requirements, such as angle tolerances or joint strength, and recommends the most suitable cutting (e.g., laser, waterjet) and welding (e.g., TIG, PAW) techniques to achieve the best results while controlling costs.- Example: For a water treatment titanium anode order with a titanium mesh surrounded by titanium frame strips, we suggested cutting the mesh and frame to size, brushing and sintering them separately, and then welding them. This maintained coating integrity and reduced deformation from stress release after sintering. However, the client insisted on coating all surfaces, requiring cutting and welding before brushing and sintering. As a result, the titanium mesh and frame experienced different stress releases during sintering, causing warping. We had to remove the warped parts, flatten them, and re-weld, which increased costs and production time.
Prototype Validation:
Before mass production, we can create small prototypes that match the final design. For example, in a recent plating industry project, we produced a 50mm x 50mm prototype with a 30° bend angle, using the same cutting and welding parameters as the final product. This allowed us to simulate angle changes during sintering and optimize production parameters.
2. Efficient Problem Solving During Production
Comprehensive Technical Guidance:
Our experts provide full support in choosing the sequence of cutting, welding, and brushing processes to ensure smooth transitions. We help clients prioritize critical processes, such as completing cutting and welding before brushing and sintering, to reduce the impact of stress release.- Example: For an anode with a 45° bend angle, we recommended cutting and welding before coating and optimized welding parameters (current: 80A, welding speed: 150mm/min) to minimize deformation during high-temperature sintering. For cases where clients altered the sequence, we offered correction solutions to resolve welding deformation issues.
Preventative Solutions:
We focus on preventative measures, such as simulating the effects of processes before production. Thermal simulations predict angle deviations under specific sintering conditions, allowing us to adjust cutting and welding tolerances and refine the sequence based on post-sintering results to ensure the final product meets specifications.
3. Flexible Support Options
- Comprehensive Remote Support:
Our team is available via video calls, phone, or email to troubleshoot cutting precision and optimize welding strength in real time. - Pre-Production Simulation Services:
For critical projects, we offer simulation services to identify potential issues early. For example, in a batch of titanium anodes sintered at 750°C, simulations revealed a 0.5° angle deviation. We adjusted the initial cutting tolerance by 0.4mm to ensure accuracy in the final production.
4. Long-Term Collaboration for Process Improvement
