The invention discloses an electromagnetic melting connection structure for a plastic pipeline, and belongs to the technical field of pipeline connection. The electromagnetic melting connection structure comprises a plastic pipe and a plastic pipe joint, wherein the plastic pipe joint is provided with at least two connecting ends which are communicated; the plastic pipe is inserted into the plastic pipe joint in which at least one connecting end is positioned; a spring which is electromagnetically welded with the plastic pipe joint and the plastic pipe is arranged between the plastic pipe joint and the plastic pipe; a step through hole and a cascade step hole positioned at the outer edge of the step through hole are formed inside the plastic pipe joint; the plastic pipe extends into the step through hole; and the spring butts against a cascade step of the cascade step hole, and contacts the corresponding outer surface of the plastic pipe. In the scheme, the electromagnetic melting connection structure is simple, fewer assembly parts are adopted, the spring with low cost is needed only to be used as a heating carrier, and the heating carrier and the plastic pipe joint are in split arrangement, so the electromagnetic melting connection structure is easy to implement and convenient to operate; and due to the adoption of electromagnetic induction heating, the aims of saving electricity and reducing consumption and cost are fulfilled by welding the spring and the plastic pipe and the plastic pipe joint.
