BH Fast Carbon and Carbon-Nitrogen Co-Penetration Technology
Abstract: BH fast carbon and carbon-nitrogen co-penetration technology is the use of high-frequency current technology to form a high-temperature arc in a short time to quickly penetrate the workpiece. This technology not only increases the effect of carbon nitrogen co penetration, but also reduces production costs. This article mainly introduces its principle, advantages and applications.
Introduction
BH fast carbon，it is a welding process that uses carbon as the main welding material, without adding any other ingredients. This technology was first developed in the 1950s and is mainly used for the welding process of cast iron, low-alloy steel, and some steels. The advantage of this method is that it greatly simplifies the preparation process of the cast iron welding process and reduces the production cost and welding time, making it widely used in the welding process of different metals and alloys.
Carbon-Nitrogen Co-Penetration Technology
Carbon-Nitrogen Co-Penetration Technology is a new welding process which combines the advantages of the BH fast carbon process and the nitrogen deep penetration technology. In this process, the high-frequency current generates high temperature arc in a short time and instantly penetrates the workpiece to form a carbon nitrogen composite layer. The significant advantage of this process is that the carbon nitrogen co-penetration layer is significantly harder and more wear-resistant than the traditional layer.
Advantages
BH fast carbon and carbon–nitrogen co–penetration technology has several advantages:
1) Low production cost: This technology greatly simplifies the welding process, saving costs.
2) High penetration depth: The high-frequency current can penetrate through the workpiece instantly and the penetration depth can be about 10-13mm.
3) Hard surface: The generated carbon nitrogen co–penetrated layer is significantly harder than the traditional welding layer, which significantly improves the wear resistance of the welding parts.
4) High welding speed: This technology can greatly reduce welding time and improve welding efficiency.
Application
BH fast carbon and carbon–nitrogen co–penetration technology are widely used in many industries, especially in automobile, logistics, machinery, and military industries. This technology is used for welding such parts as brake frame, frame, tools and molds, wheel hub, axle, and other vehicle and ship components. This technology is also used for the welding process of connecting rods, crankshafts, and other parts in the engine manufacturing industry.
Conclusion
In conclusion, BH fast carbon and carbon–nitrogen co-penetration technology is a new welding process combining the advantages of the BH fast carbon process and the nitrogen deep penetration technology. It has the characteristics of low production cost, high penetration depth, hard surface, and high welding speed. This technology is widely used in automobile, logistics, machinery, and military industries.
