6 Practical Skills for Programming Welding Robots
The work of the welding robot is carried out in accordance with the pre-programmed program, so programming is the key point. Since programming cannot be done in one step, it needs continuous inspection and improvement in practical applications, but some skills still need to be followed.
(1) When programming the welding robot, a reasonable welding sequence must be selected. Generally, the welding sequence is formulated to reduce the welding deformation and the length of the welding gun travel path.
(2) The space transition requirements of the welding gun are short, smooth, and safe movement trajectory.
(3) Optimize welding parameters. In order to obtain the best welding parameters, welding tests and process qualifications can be carried out by making working test pieces. And need to adjust welding parameters and welding gun posture according to actual requirements to form a good program.
(4) Use a reasonable position of the positioner, welding torch attitude, and the position of the welding torch relative to the joint. After the workpiece is fixed on the positioner, if the welding seam is not the ideal position and angle, the positioner should be adjusted continuously during programming, so that the welded seam reaches the horizontal position successively according to the welding sequence. At the same time, it is necessary to continuously adjust the position of each axis of the robot, and reasonably determine the position and angle of the welding gun relative to the joint and the length of the welding wire. After the position of the workpiece is determined, the position of the welding gun relative to the joint must be observed by the programmer’s eyes, which is more difficult. This requires programmers to be good at summing up the experience.
(5) Insert the gun cleaning program in time. After writing a certain length of welding program, the gun cleaning program should be inserted in time to prevent welding spatter from blocking the welding nozzle and contact tip, ensure the cleaning of the welding gun, improve the life of the nozzle, and ensure reliable arc ignition. Reduce welding spatter.
(6) Generally, the programming cannot be done in one step. It is necessary to continuously inspect and modify the program during the robot welding process, adjust the welding parameters and welding gun attitude, etc., to form a good program.
Robotic welding is a little complex process, could not take the task lightly when operate it, but you could gain experience by trial and error.
Any steps you take to make programming a smoother, more effective process can optimize production.
