Arc welding method of ABB welding robot using touch sensor

摘要

The present invention relates to an ABB welding robot, and more particularly, to a method for arc welding by accurately detecting a welding position of a welded object using an ABB robot touch sensor. Conditioning step (reference and detection voltage on, contactor off). The touch sensing step (stores position data in the position register during position detection), the conditional step (welding and detection voltage off, contactor on) during welding, and the practical welding step. Welding Work Touch Sensing Program Except touch sensing program, arc welding is possible with only the welding program, which simplifies the touch sensing method, and greatly reduces the welding program and welding time of the welding furnace. Due to the robot's dropping of the weld plate, the weld defects can be prevented from occurring due to the excessive tolerance of the welded object.
