熱ガス溶接は、 熱可塑性樹脂 materials using a stream of heated gas, typically air, to soften the surfaces. A specialized heat gun directs the hot gas onto the joint area and a plastic filler rod simultaneously. As the base material and the rod melt, they are pressed together, fusing upon cooling to form a continuous, solid bond. Because the filler rod must match the base material, the plastic is identified first, and a plastic identification chart helps choose the right rod.
