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.

2. When using hot water for a long time, the number of hot water taps should be minimized. Because every time the hot water faucet is turned on and off, the boiler will need to be restarted. When the water starts, the water will slowly heat up. This wastes time and increases the workload of the boiler.
3. Turn off or turn down radiator valves in unoccupied rooms. If your housing area is large, there are many rooms, and the population is relatively small, then the radiator valve of a room that is not occupied or that is used infrequently can be completely turned off or turned down. This is equivalent to reducing the heating area and not only saving energy. In addition, the rise in temperature during normal use of space heating will also increase, reducing gas consumption.
4. When there is no person in the house during the daytime, it is not advisable to turn off the boiler immediately when walking. If the boiler is turned off immediately, the wall-hung boiler is set to high-grade for quick heating after off duty, which is equal to starting from the beginning. Before the boiler set temperature reaches the room temperature, the boiler needs time to run intensively, thus increasing the gas consumption. It is not environmentally friendly and energy-saving. It also increases the time for households to freeze.
5. When the family is not inhabited for a long time, the water in the boiler and the radiator should be drained. This saves you from wasting gas, not to mention that the boiler or radiator is frozen or leaking.
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
Wall-hung boiler energy-saving tips
1, when using hot water, it is not appropriate to open the hot tap to the maximum temperature. The wall-hung boiler starts to heat the water for a certain period of time. Even if the hot water tap is turned to the maximum, there will not be hot water flowing out. This will waste some cold water. It should be turned on first and then slowly enlarged, so that it can save energy Water, and the warming of water will be faster.
