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

Some commonly used nickel-based alloy powders for PTAW include:
1. Inconel 625: This alloy powder is widely used for PTAW due to its high strength, excellent resistance to corrosion, and oxidation at elevated temperatures. It is commonly used in applications involving seawater, chemical processing, and aerospace industries.
2. Hastelloy X: This alloy powder is known for its high-temperature strength and oxidation resistance. It is commonly used in applications involving gas turbine engines, industrial furnace components, and chemical processing.
3. Monel 400: This alloy powder is known for its excellent resistance to corrosion, particularly in marine environments. It is commonly used in applications involving seawater, chemical processing, and oil refining.
4. Inconel 718: This alloy powder is known for its high strength, excellent resistance to corrosion, and good weldability. It is commonly used in applications involving aerospace, oil and gas, and nuclear industries.
5. Inconel 601: This alloy powder is known for its excellent resistance to high-temperature oxidation and corrosion. It is commonly used in applications involving heat treatment equipment, chemical processing, and power generation.
These nickel-based alloy powders can be used in PTAW processes to create high-quality welds with excellent mechanical properties and resistance to corrosion and high temperatures.
①If the valve body is lined with anticorrosive lining, it should be made of corrosion-resistant cushion when installed on the pipeline, and be careful not to damage the valve body flange sealing surface. ② diaphragm storage, should be installed in the bag, on the wooden shelves, to avoid direct sun exposure and contact ozone, heavy objects can not be stacked. . ③ valve storage, should be fully open state, to ensure that the diaphragm is stress-free state, especially the spring-off type diaphragm valve should pay more attention to this point. The valve flange ends should be sealed with paper to prevent moisture and dirt from entering. ④ valve in use, can not be over-closed, once the diaphragm pressure valve body weir surface can be. Valve opening speed is not too fast, too fast load forces will be added to the diaphragm screw, the diaphragm will be damaged. ⑤ on the diaphragm and lining should be regularly inspected to prevent corrosion and tear damage to other parts and cause accidents. ⑥ remove and replace the valve, the fluid should be cut off on both sides, drain raffles, and good personal protection (wear protective clothing, masks, gloves, etc.) to prevent corrosive fluid on the human injury.
