The entire equipment is equipped with a fully digitalized intelligent welding robot and self-developed intelligent welding power sources. These technologies represent a significant advancement compared to imported equipment from overseas manufacturers.

I.Technological advancement: Real-time monitoring of all parameters.

The system features a multi-sensor fusion unit that can automatically collect and analyze welding voltage, output current, mechanical welding angle, wire feeding speed, protective gas flow rate, and other critical operational parameters with millisecond-level precision. The system is equipped with a database of welding processes specifically designed for nuclear power applications, covering all types of welding processes such as stainless steel, special alloys, and thick-wall pipes. It can automatically select the optimal welding process curve based on the thickness of the base material and the type of groove. The system also dynamically adjusts the heat input throughout the welding process, effectively eliminating high-risk welding defects such as pores, lack of fusion, and intercrystalline corrosion. All data related to the welding process is fully recorded and traceable, ensuring compliance with strict nuclear safety regulations.

II. Technological Innovation: Advanced high-dynamic, wide-angle welding monitoring system, capable of adapting to complex working conditions in various postures.

Thanks to advanced lens design and visual algorithms, this device enables operators to clearly observe the condition of the weld pool and adjust welding parameters in real time. It also accurately determines the position of the weld and the contour of the joint. By breaking away from the limitations of traditional equipment, this device can perfectly adapt to all welding postures, including flat welding, vertical welding, horizontal welding, and overhead welding. It is compatible with extremely complex welding conditions such as large-diameter, thick-wall pipes, irregularly shaped surfaces, and narrow, confined spaces. In scenarios where manual operation is difficult, such as confined spaces in nuclear power plants or handling irregularly shaped components, this device can perform autonomous operations with pinpoint accuracy, with positioning errors controlled within sub-millimeter levels. This significantly reduces the need for manual intervention, making it suitable for the most demanding special welding environments in the industry.

III. Market Application Promotion: Achieve import substitution in key areas, and create growth opportunities in multiple markets.

This intelligent welding system has already been successfully implemented in key safety-related fields such as nuclear power and high-end chemical industry pressure vessels. It has completely replaced overseas automated welding equipment, which had long dominated the market, thereby eliminating the need for foreign-made equipment in nuclear power industry. Thanks to its modular and digital architecture, the application scope of this product can be further expanded to various high-value sectors, including thermal power energy equipment, shipbuilding, aerospace components, and heavy-duty high-end equipment manufacturing. Once widely adopted, this system will significantly reduce the costs of purchasing and maintaining advanced welding equipment in the industry. This will lead to rapid growth in sales of domestic intelligent welding equipment in various target markets, thereby accelerating the process of self-reliance in welding equipment manufacturing across the entire industry.

For a long time, the market for automatic welding equipment for the high-end parts of nuclear power plants has been dominated by foreign brands. The implementation of this complete system has effectively broken down these foreign technological barriers, addressing the shortcomings in domestic advanced and intelligent welding equipment for nuclear power plants. This has laid a solid foundation for the localization and intelligent construction of nuclear power projects. In addition to nuclear power applications, this modular intelligent welding robot also has extensive cross-industry applications. It can be widely used in various fields such as industrial welding of thick steel plates, thermal power energy equipment, shipbuilding, and high-end aerospace components.
