• Aerospace components
• Marine environments and offshore structures
• Chemical and petrochemical industries, especially for pipes, reactors, and tanks
• Heat exchangers, pressure vessels, and boilers
• Medical implants and devices
• Food processing equipment (where corrosion resistance is crucial)

Storage and Handling

• Storage: Store the titanium welding wire in a clean, dry environment, away from contaminants, moisture, and chemicals. Ensure the wire is kept in its original packaging until use to prevent oxidation.
• Handling: Handle the wire with clean gloves to avoid contaminating the surface. Keep the wire free from oils, grease, and moisture, as these can negatively affect the weld quality. Always ensure the welding area is free from contamination to achieve optimal results.
