| 摘要 |
An induction heating generator is described for braze-welding metallic pipes (37) with a continuous process under a controlled atmosphere, comprising at least one heating inductor (33) composed of two half-inductors (33',33") in series whose winding directions for their windings are one opposite to the other for removing residual induced voltages on the pipes. The generator may be further equipped with a quartz tube (39) placed inside the inductors (33) and in which the metallic pipes (37) pass together with the controlled atmosphere gas (35). The generator may further include at least one removable sealing insert (41) to join two contiguous inductors (33). For every medium- and/or high-frequency section of the generator, a load matching system may finally be provided to compensate for external diameter variations of the pipes (37), the system being interlacedly handled by a programmable controller (P.L.C.). <IMAGE> |
