Abstract
The soldering is one of the most important in the modern manufacturing technology, to improve the stability and reliability of the welding quality is crucial. Limited to the economic and technical reasons, the basic welding production operations in China or manual operation, to change this situation the only way is the use of automatic welding technology, welding robots instead of workers welding operation automation tools.
Three degrees of freedom in the welding robot welding robot as research object, according to its technological requirements, developed an excellent welding quality, high reliability, versatility, easy to operate, low-cost three-degree-of-freedom arc welding robot.
The main contents are as follows:
Welding robot technology status and development trend.
Analysis of the welding process process requirements to clear three degrees of freedom welding robot control system design the overall objective of the program.
In accordance with the industrial computer + motion controller "program, set up the hardware structure of the control system. Computer programming language developed motion control system software.
Robot with a common CO2 gas shielded welding machine supporting welding performance test. Experimental results show that the welding robot can achieve uniform weld automatic welding, weld, high efficiency, and control the operation of the system is accurate, reliable, welding robot control system overall technical program, stable performance.
Keywords: welding robots, CO2 welding, the motion controller, the control system.
