Full of salted work clothes, full of oily gloves, sweaty face, full of passion. Since November 10, the overhaul of the electric chlorine plant of Tianye Chemical Company has been in full swing in the autumn. 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 order to ensure that overhauling can play a greater role, Tianye Chemical Company's electrochlorine plant has carried out detailed deployment and arrangements prior to overhaul. According to the company's unified repair time node, the production system was meticulously sorted and the problems found during the operation were investigated. After research and confirmation of the maintenance project, the maintenance plan was formulated, "fixed time, quality, and responsible person" to ensure that the inspection and repair activities can be completed on time and in high quality.
It is reported that the major overhaul of the Tianye Chemical Company's electrochlorine plant mainly includes overhauling large-scale equipment and processing pipeline leakage points to ensure stable and reliable winter production operations. At the same time, using the opportunity of system-wide parking during maintenance, we will do a good job in the maintenance and maintenance of various equipment to ensure safe production in winter.
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
