The system performance of the welding control system is highly efficient, as demonstrated in reference 6 (20004249). This intelligent seam tracking system utilizes a visual sensor to detect the arc welding area and employs image processing techniques to accurately locate the weld seam. A parameter self-adjusting fuzzy controller is also designed to regulate the movement of the welding torch, significantly improving the accuracy of the seam tracking process.
Another notable development is the capacitor energy storage seam welding machine microcomputer controller (20004250), introduced by Zhang Yong. The design incorporates a single-chip microcontroller that manages charging voltage and the on-off time ratio during welding, greatly enhancing the technical performance of the welding machine. The controller includes parameters such as welding current and energization time, which are essential for ensuring consistent welding quality. It also features diagnostic alarms, making it reliable and suitable for various applications. This controller has been successfully applied in the welding of micro-parts and precision components, demonstrating its practical value in advanced manufacturing.
In terms of welding structure and design, research (20004251) focuses on developing a product information model based on features and object-oriented principles. This model is crucial for integrating welded structures into broader manufacturing systems. The study outlines key features such as shape, joint type, groove geometry, material properties, and assembly details, aiming to support subsequent processes like process planning, clamping, and robot path optimization. A prototype software was developed to test this model, with applications in underwater construction projects.
Reliability analysis of welded structures with buried cracks (20004253) introduces a stochastic finite element method to evaluate structural safety. This approach accounts for random variables such as crack size, offering a more accurate assessment of structural integrity compared to traditional methods. It provides a new pathway for evaluating defective welded structures, enhancing safety and reliability.
In the field of assembly welding process design, an objective method (20004254) was proposed, focusing on large-scale positioning techniques. This method involves decomposing objectives into static and dynamic models, supporting complex welding assembly processes. It has potential applications in languages like C++ and other process-oriented programming environments.
New trends in automotive material technology (20004255) highlight advancements in welding techniques such as gas-shielded metal arc welding and inert gas shielded welding. These developments contribute to improved material performance and efficiency in automotive production. A German company's screw and sleeve combination device is used to assemble components without risk of loss during further processing, meeting high standards in load capacity, corrosion resistance, and ease of installation.
Welding technology for Shantou Bridge (20004256) includes precise cutting, butt welding, fillet welding, and horizontal welding techniques using large-scale tooling. Measures to control deformation were implemented, resulting in successful outcomes. Research on large I-beams (20004257) analyzed bending and angular deformation, proposing effective solutions such as symmetrical welding and movable vertical ribs to minimize distortion.
Other studies, such as the welding of boiler headers (20004259) and high-frequency electric welding of steel pipes (20004260), focus on quality control and structural integrity. The development of air-tight plates for high-energy boiler equipment (20004261) involved analyzing welding deformation and optimizing the assembly sequence to ensure structural stability. These innovations reflect ongoing efforts to improve welding technologies across various industries.
