Apparatus and method for detecting axial movement of U-tube in pipe-to-plate welding system

摘要

The present invention relates to an apparatus and method for detecting axial movement of a U-tube in a piping-to-plate welding system, which controls axial movement of the probe through a probe axial movement drive device so as to contact a plate or U- Controlling the rotation of the probe such that the probe is switched between a position toward the tube plate or a position toward the end of the U-tube through the probe radial rotary drive; The probe moves toward the end of the U-shaped tube and moves along the axial direction to calculate the first position of the probe by U- The signal processing system compares the first position with the second position to calculate the second position of the probe by comparing the U-shaped tube end and the flushing of the tube plate with each other And if the flush satisfies the set requirement, the arc welding is not performed if the flush does not satisfy the requirement, and if the flush satisfies the requirement, the pipe-to-plate welding is performed by arc welding to the pipe- Ensure joint quality and prevent clogging of piping.
