[Problem to be solved by the invention] In the case of the prior art, the plastic wire 7 is sufficiently melted, and the groove surface 8 is melted and joined while being melted and added to the groove joint surface 8. Melt welding requires high heat, which causes deterioration of mechanical properties (embrittlement) in the heat-affected zone of the plastic base materials 1 and 2.
There were problems in that the quality of the bonding was poor, and that the workpiece was significantly deformed when it was performed with a large heat input.
