Pipeline hot melting butt joint technology and hot melting butt joint equipment

The invention belongs to the field of pipeline welding, provides a pipeline hot melting butt joint technology and hot melting butt joint equipment and solves the problem that the correction is large when a pipeline is welded. According to the scheme, the pipeline hot melting butt joint technology comprises the following steps: 1, preparing: levelling and cleaning to-be-butt joint end faces of a pipeline, arranging two heating plates at an interval, and enabling the two heating plates to be propped against the adjacent pipeline; 2, heating: heating the heating plates to melt the part, propped against the heating plates, of the pipeline; 3, crimping: pushing the pipeline towards the heating plates to deform the part, propped against the heating plates, of the pipeline into curled edges; 4, switching: rotating the heating plates in the circumferential direction, moving the heating plates in the axial direction simultaneously to enable the heating plates to deviate from the pipeline propped against the heating pl
