1. Titanium TIG welding wire (tungsten inert gas welding wire)
- Process characteristics
Principle: A Tungsten electrode is used as the electrode, argon gas is used to protect the arc and molten pool, and TIG welding wire needs to be added manually or automatically to fill the weld during welding.
Arc characteristics: stable arc, concentrated heat, delicate weld formation, suitable for precision welding.
Shielding gas: pure argon (Ar≥99.99%), gas purity must be ensured to avoid oxidation of titanium alloy.
- Main application scenarios
- High-precision and high-demand welding scenarios: aerospace, medical implants, electronics and precision instruments
- Thin plate or ultra-thin plate welding: Suitable for titanium plate welding with a thickness of ≤3mm,
- Welding repair and repair welding: Local repair of formed titanium alloy parts requires precise control of the welding heat affected zone.
- Advantages and disadvantages
- Advantages: High weld quality, beautiful formation, suitable for single-sided welding and double-sided forming; no need to add flux to avoid welding slag residue.
- Disadvantages: Low welding efficiency, not suitable for mass production; High technical requirements for welders, and the distance between the tungsten electrode and the molten pool must be strictly controlled to avoid tungsten contamination.
2. Titanium MIG welding wire (metal argon arc welding wire)
- Process characteristics
- Principle: MIG welding wire is used as the electrode, which is continuously fed through the automatic wire feeding mechanism. The arc melts the welding wire and the base material to form a weld, and argon or argon-helium mixed gas is used for protection.
- Arc characteristics: high current density, high deposition efficiency, suitable for thick plates or large-scale welding.
- Shielding gas: usually pure argon, or a mixture of argon + helium (to increase the penetration depth) and argon + hydrogen (to improve arc stability).
- Main application scenarios
- Thick plate structure and mass production: chemical and marine engineering, automobiles and engineering machinery, buildings and bridges
- Welding and surface strengthening: cladding wear-resistant or corrosion-resistant layers (such as TC4 cladding layers) on the surface of titanium alloy substrates to increase the service life of components.
- Advantages and disadvantages
- Advantages:
- High welding efficiency, fast deposition speed, suitable for automated production lines (such as robot welding).
- The welder's operation requirements are lower than TIG welding, and it is easy to master.
- Suitable for welding thick plates (can be completed through multi-layer and multi-pass welding), with a large penetration depth.
- Disadvantages:
- The weld formation is rougher than TIG welding, and spatter may occur.
- The equipment is complex and needs to be equipped with a wire feeding mechanism and a precise gas flow control device.
- Thin plates are easy to burn through when welding, and the heat input needs to be strictly controlled.
