The Ideal Option For Thermocouple Welding

Thermocouples play a crucial role in temperature measurement, utilizing the current generated by heating one end of two dissimilar metals. These sensors are known for their high accuracy and can be designed using a wide range of metals and corresponding calibrations. While general-use thermocouples employ base metals for the two dissimilar wires, noble metal thermocouples are preferred for high-temperature applications. Achieving precise welds between these wires and the thermocouple components is vital for ensuring measurement accuracy and device performance.

Thermocouple Welding Options

Enhanced Weld Strength and Performance
Percussion Welder offers a precise, accurate, and controlled option for welding thermocouples. Unlike other thermocouple spot welders, our system offers increased weld strength and performance with a bonded weld that is strong and durable. Our thermocouple wire welder uses both heat sources and pressure to fuse the molten ends of the two delicate wires for a butt weld that does not require filler, solder, or crimping.

Controlled Heat and Pressure
Percussion Welder is the ideal option for thermocouple welding due to its precise control of both heat and pressure. This technology uses an electrical arc to generate a spark, which melts both ends of the wire simultaneously. The pressure applied is light and consistent, ensuring that there is no damage to either wire’s hardness or resistance. By controlling the gap and the timing of the electrical arc and percussion, the welds are consistent, ensuring quality welding on both low and high-volume levels.

Integration with Automation

Efficient Thermocouple Welding Techniques
The Percussion Welder can also be integrated with automation, providing efficient thermocouple welding techniques for any manufacturing and industrial processes. This integration allows manufacturers to achieve consistent welds with minimal effort and cost, making it an ideal solution for high-volume production.

Robust and Long-Lasting Welds
Picking Percussion Welder for your thermocouple welding offers unmatched control, accuracy, and precision. With its ability to be integrated into automated processes, manufacturers can achieve robust, trustworthy, and long-lasting welds. These welds are perfect for high-temperature applications, setting a new standard for thermocouple welding solutions.

FAQ

Why does the weld matter for a thermocouple?

A thermocouple measures temperature using the current generated by heating one end of two dissimilar metals. Precise welds between the wires and components are vital for measurement accuracy and device performance.

Which thermocouple wires can be welded?

Both base metals, used in general-purpose thermocouples, and noble metals, preferred at high temperature.

How is the weld made?

An electrical arc melts both wire ends at once and light pressure brings them together into a butt weld that needs no filler, solder or crimping.

Does the pressure damage the wire?

No. The pressure is light and consistent, so there is no damage to either wire's hardness or resistance.

Can it be automated?

Yes. Integration with automation is described for consistent welds at low and high volume.

Where can I find settings for my wire?

Our lab weld-schedule database includes Chromel and Alumel thermocouple alloys, as starting points rather than guarantees. Contact us to confirm for your wire size.
