Plasma Spray Welding Alloy Powder Physical Properties (JB/T 3168.1－1999)

，要原创，请各位把价格报出来 The Physical performance of the Alloy Powder for Gas Tungsten Arc Welding JB/T 3168.1 –1999 Gas Tungsten Arc Welding is a welding process that utilizes a non-consumable tungsten electrode to generate the weld. The electrode is shielded from the atmosphere by an inert gas, usually Argon, so that the metals to be welded do not become contaminated by oxygen in the atmosphere. Shielded or inert, gases such as argon or helium are the most widely used, which will protect the weld area from atmospheric contamination. The gas also assists in transferring heat to the weld area and in forming and shaping the weld pool, so the variant arc comes in many shapes, including the pointed arc, the keyhole arc and the full craters. In order to ensure the welding quality, the alloy powder is a major component in the welding process. The content of the alloy powder can range from 25%, and affects the performance of the welding. For example, too little alloy powder and the mixture is not well-connected, so the welding material can be easily oxidized, reducing the overall quality of the weld. In order for the alloy powder to work properly, it must meet certain specifications, as described in JB/T 3168.1 –1999. According to JB/T 3168.1 –1999, the alloy powder must have a surface roughness (R/Rmax) of not more than 0.1mm, a bulk density of more than 0.85g/cm3, an oil absorption rate of not more than 10%, and a particle size distribution of not more than 1mm. Additionally, the alloy powder must have certain chemical components in order to meet the requirements of the welding process, including carbon, manganese, silicon, and molybdenum. The alloy powder must also have less than 0.3% sulfur and phosphorus, in order to ensure that the welding process results in a strong weld joint. Finally, the alloy powder must be free from any impurities, such as zinc, lead, cadmium, and mercury, in order to ensure a clean weld joint. By meeting these specifications, the alloy powder is able to provide reliable performance and a quality weld joint when used.

The physical properties of alloy powders for plasma spray welding (JB/T 3168-1999)

Alloy powders for plasma spray welding (PSW) is process that is adopted in industries such as automotive and aerospace to protect components from operational and environmental damage. Its aim is to provi-de a protective coating on the surface of the component as part of an overall strategy for improving the overall performance of the component by creating a durable protective layer. JB/T 3168-1999 provides guidelines and specifications for the physical properties of alloy powders for this process.

The physical properties of the alloy powders are key to the successful implementation of the PSW process. This includes parameters such as the size, shape, density and composition of the alloy particles. These parameters determine how effectively the plasma spray welding process can be applied and can be used to identify the best powder for use in the process. It is important that the powder selection process is based on the specific design requirements of the component and the environment in which it will be operating.

The physical properties of the alloy powders for PSW must be analyzed in order to ensure that they are suitable for the application. The JB/T 3168-1999 code outlines a wide range of parameters that are required for evaluation. This includes parameters such as the particle size distribution and shape, the apparent density, the chemical composition and the surface condition. The data collected from these analyses helps in selecting the appropriate powder for the specific application.

In addition to the physical properties, the performance characteristics of the alloy powders must also be considered. These include parameters such as the fusion behavior, cracking potential, toughness, hardness, oxidation behavior and spalling resistance. These parameters are evaluated in laboratory conditions and can be used to identify a suitable powder for the application at hand.

In conclusion, JB/T 3168-1999 provides guidelines and specifications for the physical properties of alloy powders for plasma spray welding (PSW). The physical properties include the size, shape, density and composition of the alloy particles. In addition, the performance characteristics such as the fusion behavior, cracking potential, toughness, hardness, oxidation behavior and spalling resistance must also be evaluated. These parameters are essential for identifying the best powder for use in the PSW process.
