Cobalt-based alloy powders are commonly used in plasma transfer arc welding (PTAW) due to their excellent high-temperature properties and resistance to wear and corrosion. These alloys are typically composed of cobalt as the base metal, with various alloying elements such as chromium, tungsten, nickel, and carbon added to enhance specific properties.

In recent years, with the development of new industries such as ships and aviation, the demand for measurement and inspection with a strong value-added force is increasing rapidly. Especially for the shipbuilding industry, the strong value tension sensor is mainly used to detect the thrust of large ships, and then based on the test data to improve the ship's power design, control and control the quality of the ship's components, so the great value of pulling force measurement is of great significance to the development of the shipbuilding industry. Due to the fact that the forceful tension sensors generally have major self-contained problems (about 1 ton), large dimensions (more than 1 meter long), and mismatched detection space, it is difficult to measure the pull force and the force measurement service has been provided. It has become a key bottleneck restricting the quality improvement of the shipbuilding industry.
According to the customer's measurement requirements, Hubei Metrology Institute, with its strong technical strength, carefully and carefully performed a large number of preliminary preparations, strictly formulated technical service plans, and provided special matching tooling for sensor inspection and sensor connection, ensuring a large number of sections. Tensile force measurement security, successfully completed the full-scale measurement testing, has received high customer evaluation and recognition, and further enhance the hospital's credibility in the field of domestic mechanical measurement services. The hospital will continue to adhere to the "market high positioning, high level of capabilities, service quality," the working guidelines, and actively expand the market of strong mechanical measurement testing services, and strive to Hubei, the central region and even domestic ship manufacturing and large-scale equipment manufacturing quality development Provide better service and support.

The use of cobalt-based alloy powders in PTAW offers several advantages, including:
1. High-temperature strength: Cobalt-based alloys exhibit excellent strength and resistance to deformation at elevated temperatures, making them suitable for welding applications that involve high heat.
2. Wear resistance: These alloys have a high hardness and resistance to wear, making them ideal for welding applications where the welded parts are subjected to abrasive or erosive conditions.
3. Corrosion resistance: Cobalt-based alloys offer good resistance to corrosion, making them suitable for welding applications in aggressive environments, such as those involving chemicals or saltwater.
4. Thermal conductivity: Cobalt-based alloys have good thermal conductivity, allowing for efficient heat transfer during welding and reducing the risk of heat-affected zone (HAZ) defects.
5. Compatibility with other materials: Cobalt-based alloys can be easily welded to a wide range of base metals, including stainless steels, nickel alloys, and other cobalt-based alloys, providing versatility in welding applications.
To use cobalt-based alloy powders for PTAW, the powder is typically fed into the plasma arc using a powder feeder. The powder is then melted by the high-temperature plasma arc and deposited onto the workpiece, forming a weld bead. The specific welding parameters, such as arc current, travel speed, and powder feed rate, will depend on the specific alloy and application requirements.
It is important to note that the selection of the cobalt-based alloy powder should be based on the specific welding application and the desired properties of the final weld. Different cobalt-based a
