The 4 kinds of problems and solutions in the application of welding robots are as follows:
(1) There is a partial welding problem: it may be because the welding position is incorrect or there is a problem when searching for the welding gun. At this time, it is necessary to consider whether the TCP (the position of the center point of the welding gun) is correct and adjust it. If this happens frequently, check the zero position of each axis of the robot, and correct the center zero calibration.
(2) Undercut problem occurs: it may be improper selection of welding parameters, wrong welding gun angle or welding gun position, which can be adjusted appropriately.
(3) Porosity problem: Poor gas protection, too thick primer on the workpiece, or the wrong position, which can be adjusted appropriately.
(4) Excessive spattering problem: It may be due to improper selection of welding parameters, gas component reasons, or too long welding wire external inspection length. You can appropriately adjust the size of the robot power to change the welding parameters, and adjust the gas proportioner to adjust the mixed gas ratio. Adjust the relative position of the welding gun and the workpiece.
(5) An arc crater is formed after cooling at the end of the weld. When it is programmable, add submerged arc work to the work step to fill it up.
