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.
Metal bellows have the characteristics of pressure, axial force, lateral force or bending moment can produce the corresponding displacement, and with pressure, vacuum seal, corrosion resistance, temperature stability and long service life and other properties. Therefore, it is more and more widely used in many industrial fields. Bellows as a seal isolation element in the valve application. In a variety of bellows valves, whether it is cut-off valves, throttle valves, regulators or valves such as valves, bellows are sealed as a packing seal element. In the process of valve work, the bellows together with the stem axial displacement and reset. At the same time it also withstands fluid pressure and guarantees sealing. Compared with the packing seal valve, bellows valve with higher reliability and service life. Therefore, the bellows valve in the nuclear industry, petroleum, chemical, pharmaceutical and aerospace industries have been widely used. In practical applications, the bellows often with other components such as flanges, take over and stem welding such as one to form a bellows-like components. Welding has become an indispensable component in the production of bellows an important process. With the development of scientific research and production, new requirements are put forward on the corrugated pipe welding tools and equipment. According to these requirements, the need to develop a new bellows welding equipment. Search Keyword: More Valve Technical Articles
