摘要:
An apparatus for treating continuously welded metallic tubes comprises a series of longitudinal inductors mounted on movable carriages which are adapted to be pivotal co-axially with respect to the tube in response to the angular position of the weld bead formed on the tube so that each of the inductors remains centred on this weld bead.
