    Patent number: 4441010
    Abstract: Process for the lateral positioning of a member relative to a joint formed between two metal surfaces and having discontinuities and using at least one eddy current probe, wherein the signal supplied by each of the probes are processed to obtain at least one positioning signal varying with the displacement of the axis of the corresponding probe relative to the axis of the joint and at least one signal indicating the presence of a discontinuity and transmitted when the corresponding probe faces a discontinuity of the joint, wherein the member is laterally displaced as a function of variations of the positioning signal and wherein the control of the displacement of said member is interrupted as a function of variations of the positioning signal when a signal indicating the presence of a discontinuity is transmitted.The invention also relates to an apparatus for performing this process.
