Present situation and development trend of welding robot

Abstract

in recent years, the research and application of welding robot technology has made many outstanding achievements in seam tracking, off-line programming, path planning, intelligent control and so on. With the continuous development of computer technology, intelligent control technology and artificial intelligence theory and industrial production systems, robotics and many waiting for us to study the problem of welding, especially of the path planning technology of intelligent welding robot (such as neural network algorithm, genetic algorithm, ant colony algorithm, etc.) will be the main direction of future research. In view of this, this paper analyzes the current situation and development trend of welding robot technology, for reference only.

Scheduling the Process of Robot Welding of Thin-Walled Steel Sheet Structures under Constraint

“…In the field of robotic welding, which is the topic of this paper, the authors focus on in-depth analyses of the process itself. The following issues are addressed: the selection of process parameters and the robot path supported by information systems [39], the use of additional hardware-e.g., a vision system [40], the use of genetic or memetic algorithms [41] or neural networks [42] for weld optimization analysis, or collision detection using ant algorithms [43]. Thus, in the works on robotic welding, issues are presented where the authors do not focus on the exact planning of the robot's work and the appropriate refinement of its tasks.…”

Cartesian space track planning for welding robot with inverse solution multi-objective optimization

“…Where C tt is the translation submatrix of the cartesian flexibility matrix C, and C can be expressed by equation (2).…”

“…In order to reduce production costs, improve production efficiency, and ensure welding accuracy, welding robots have become indispensable in welding operations. 1,2 Trajectory planning can make the robot move smoothly and reduce impact and vibration, which is of great significance to improving the stability, reliability, and work efficiency of the robot. 3,4 At present, scholars have conducted research on trajectory planning and have proposed some novel trajectory planning methods, such as the sine resistance network-based planning approach.…”

Design of Intelligent Medical Guidance Robot

“…For accelerating the transformation and upgrading of Chinese manufacturing, China has successively issued a series of important policy documents such as "Manufacturing in China 2025", and pointed out the research and development direction of intelligent medical robot industry [1,2]. This is of great significance to promote the rapid development of China's medical system from traditional mode to modern intelligent medical mode.…”
