Abstract: A railway-rail induction welding device (10) which comprises a copper tubular body (14) having a cooling-fluid inlet and a cooling-fluid outlet. The copper tubular body has a rail-facing rail-heating portion (18) and a cooling-fluid return portion (20). The rail-facing rail-heating portion (18) has a longitudinal extent which is non-linear and profiled to correspond or substantially correspond to one side of a railway rail to be treated. A lateral extent of the rail-facing rail-heating portion (18) is non-uniform along the said longitudinal extent.
