| 摘要 |
A peening device suitable for peening annular weld zones inside undersea pipes, the device comprising at least one peening tool, with at least one hammer actuated to perform radial reciprocating movement in translation for peening against the inside surface of the pipe and/or said weld, wherein: said peening tool has a single hammer; and said hammer is pivotally mounted so as to be capable of varying its angle of inclination relative to the surface for peening; and said device includes a carriage suitable for moving in axial longitudinal translation XX inside a pipe and for supporting means for moving said peening tool in longitudinal and radial translation, and in rotation relative to said carriage; and said hammer co-operates with means for actuating radial reciprocating movements in translation by peening by making use of electromagnetic energy and reciprocating motion inside a solenoid coil, preferably also in co-operation with a spring.
