Abstract: A magnetic inductor for heating parts by means of induction having a geometry with a density greater than or equal to 99.9% (absence of pores), produced by a plurality of welded layers formed by metal dust particles of a conductive, non-magnetic material (such as, inter alia, copper, tin, aluminum, gold, or silver), preferably copper or a copper-based alloy, having a spherical shape and a grain size between 40 and 100 ?m, and in a single-piece part including electrical and mechanical connections. Also, a method for producing the magnetic inductor with EBM technology (electron beam melting/production technology based on electron beam fusion), using a system comprising an electron gun, a vacuum chamber, a working chamber and a manipulation system.

Abstract: Induction welding device for variable diameter pipes includes three inductors configured in the shape of a cam, placed in symmetry in relation to the axial axis of the pipe to be welded, an oscillator connected to each inductor, a mechanical system connected to each inductor, designed to force each inductor to make contact with the pipe by the corresponding degree in relation to the diameter of the pipe at each position, so that the position of the inductors in relation to the pipe changes radially as the diameter of the section of the pipe to be welded also changes.
