"Love" car must first "love" the battery
According to Battery.com.cn, I believe that people who drive know that the battery is the heart of the car. Therefore, in order to drive your car better, you must learn to maintain and maintain the battery carefully. With a variety of automotive electronic equipment gained popularity, importance of the automobile storage battery maintenance is more and more mentioned. If a car does not have a battery, it is difficult to start, let alone the electrical equipment and other functions in the car. I believe that many car owners have had the same experience: because the car battery is dead, it is on the road. In the urban area, if it is in the suburbs or high-speed, it can be annoying. In the car owner's daily use, there are usually two key points: avoid excessive discharge and correct battery maintenance. Avoid over discharge When the vehicle is used for more than 3 years, there will be problems with more or less batteries. Prior to this, usually pay more attention to scientific electricity, which can effectively extend the service life of the battery. Experts remind: "After turning off the engine, long-term use of in-vehicle electrical equipment, such as audio, lighting, air conditioning, will cause the battery to over discharge, and each over-discharge will greatly reduce the battery performance; before leaving the vehicle, the car mainly checks whether There is also a power device that is not turned off; in addition, it is best not to start more than 5 seconds each time the car is started, and do not start continuously." At the same time, since the original car electronic equipment is configured according to the original vehicle power consumption, the car mainly tries to avoid using the battery external high-power electrical equipment, and do not arbitrarily modify and install the electronic equipment inside the vehicle, otherwise it is likely to be impossible. Startup issue. At the same time, there is an automatic discharge phenomenon in the battery. For vehicles that are idle for a long time, the battery may be over-discharged and cannot be started. It is recommended that the owner remove the negative connector of the battery in advance. Correct battery maintenance At present, most of the batteries on the market belong to lead-acid batteries. Xiaobian reminds the majority of owners: The acidity of lead-acid batteries is highly corrosive. Wear protective gloves and eye masks during operation. In addition, the car mainly checks whether the positive and negative battery connecting wires are loose and the battery surface is clean, so as not to affect the normal charging and discharging of the battery. The owner can also check whether the small holes in the battery cover are ventilated. If the small holes are blocked, the generated hydrogen and oxygen can not be discharged, and the electrolyte expansion is too large, which will affect the battery life. “It is best for the owner to replace the battery every two years to ensure proper use of the vehicle.†Battery power failure emergency method Usually, the owner can prepare a pair of jumpers in the car. If the battery is out of power and cannot be started during driving, the owner can use the jumper to connect the batteries of other vehicles to start his own vehicle. It is worth noting that the battery voltage of the car Must be higher than or equal to the loss of power vehicles. According to the relevant staff: "The two ends of the jumper are connected to the positive and negative poles of the two batteries respectively, and the position of the wire is adjusted. The vehicle is started for one minute and then the vehicle is turned off, and the engines of the two cars are idling for a while. "If there is no jumper, it is recommended that the owner promptly ask for help from the 4S shop. 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.
