Iron-based alloy powder is commonly used in plasma transfer arc welding (PTAW) due to its excellent mechanical properties and high resistance to corrosion and heat. This type of powder is typically composed of iron as the base metal, along with various alloying elements such as nickel, chromium, molybdenum, and tungsten.

The specific composition of the iron-based alloy powder may vary depending on the desired properties and application requirements. For example, adding nickel can increase the strength and toughness of the weld, while chromium enhances the corrosion resistance. Molybdenum and tungsten are often added to improve the high-temperature strength and creep resistance of the weld.
Iron-based alloy powders for PTAW are available in various particle sizes, typically ranging from a few micrometers to several hundred micrometers. The powder is usually fed into the plasma arc through a powder feeder, which ensures a controlled and consistent supply of powder during the welding process.
During PTAW, the powder is melted and deposited onto the workpiece, forming a weld bead. The high energy plasma arc provides the heat necessary to melt the powder and the base metal, creating a strong and durable weld joint.
Overall, iron-based alloy powder for plasma transfer arc welding offers excellent weldability, high mechanical properties, and resistance to corrosion and heat, making it suitable for a wide range of applications in industries such as aerospace, automotive, and power generation.
As an explosion-proof electrical appliance, explosion-proof air conditioners are widely used in the industrial production category, and are mainly suitable for use in flammable and explosive environments such as petroleum, chemical, oil depot, and land oil platforms. Above, I will talk about the small masters as a master: the small skills of explosion-proof air conditioning protection and maintenance.
Look at the outdoor rack for loose signs and clean the outdoor unit to ventilate the foreign objects inside the grille. Then clean the indoor unit casing, filter net, check the power supply line, plug and socket board, switch; check the easy-to-use parts, such as air deflector, sterilization, dehumidification, photocatalyst and other components, to ensure that the air conditioning condition is outstanding, no.
The detailed method of shallow cleansing is to remove the dust filter and use the vacuum cleaner to suck the small dust. If there is more dirt, wash it with warm Panyu water, then wash it with clean water and dry it. Remember, don't use a sponge to clean it, or it will destroy the dust filter. After cleaning with clean water, dry it with a soft cloth or dry it in a cool place. Do not expose it to sunlight or dry it in an open flame such as a stove to stop the deformation of the filter net.
It is necessary to confirm that the filter is completely placed in the normal gear when installing.
In addition, there are various spacers on the panel on the air-conditioner casing to easily accumulate dust, which can be cleaned with non-woven fabric or soft-skinned cloth on time, and scrubbed with neutral Panyu water not exceeding 40 °C. The outdoor unit zui is also washed once. If the air conditioner is not durable, it will not only cause the cooling and heating results to fall, but also prolong the bacteria.
