Tantalum Tube Welding Micro Non-Consumable Vacuum Arc Furnace

Product Overview

This compact non-consumable vacuum arc furnace is engineered for melting high-purity metals and alloys under a controlled argon atmosphere. It achieves extreme temperatures up to 3500°C, enabling research on refractory materials. The benchtop design is ideal for university labs and industrial R&D facilities where space and efficiency are critical.

Typical use cases include synthesizing novel alloys, preparing amorphous metals via suction casting, and sealing tantalum tubes. The system serves material science, metallurgy, and semiconductor research. Its water-cooled crucible with four positions and a rotating tube holder allow multiple samples or welds per session.

Built with robust water-cooled electrodes and reliable vacuum gauging, this furnace delivers consistent performance. Advanced safety features like over-temperature protection and a tinted window provide operator confidence, making it a dependable lab asset.

Key Features

• Ultra-High Temperature Performance: Capable of reaching 3500°C under high-purity argon, this furnace melts refractory metals and alloys that require extreme heat, expanding research possibilities. Supplementing broad temperature ranges, it accommodates everything from low-melting-point solders to high-entropy alloys.
• Rapid Vacuum and Argon Cycling: The small chamber volume enables quick evacuation to 5×10⁻³ Pa and fast argon backfill, significantly reducing cycle times and argon consumption compared to larger systems. A typical melt cycle is completed in minutes, boosting daily throughput.
• Multi-Position Water-Cooled Crucible: Four φ25×10 mm hemispherical cavities in a water-cooled copper hearth allow simultaneous melting of up to four samples, improving productivity and comparability. The symmetrical layout and effective cooling minimize cross-contamination between melts.
• Flexible Water-Cooled Electrode: An adjustable-height electrode with active water cooling provides precise arc control and stays cool during extended operation, ensuring stable melts and consistent arc ignition. The flexible positioning simplifies sample loading and observation.
• Integrated Tube Welding Station: A dedicated platform rotates tantalum tubes (φ5–14 mm diameter, 50–100 mm length) at 0–45 rpm, enabling uniform, high-quality welds for sample encapsulation or tube joining. The rotation speed is finely adjustable to match different tube sizes.
• Accurate Vacuum Monitoring: A reliable vacuum gauge gives real-time pressure feedback, helping maintain consistent process conditions and alerting users to any deviations.
• Enhanced Operator Safety: Over-temperature protection and a tinted observation window safeguard against arc radiation and accidental overheating, providing a safe working environment.
• Space-Saving Benchtop Footprint: The compact design minimizes laboratory space requirements and energy usage, fitting easily on standard workbenches. Despite its small size, it delivers industrial-grade performance suitable for demanding research.
• Intuitive Manual Controls: Straightforward electrode height adjustment and manual argon flow valves make setup quick and reduce training time for new users. This simplicity does not compromise the advanced capabilities needed for sophisticated experiments.
• Customizable Crucible Options: Beyond the standard 4-position hearth, we offer tailored crucible configurations to meet unique sample sizes or melt requirements (contact us for details).
