<p>PURPOSE:To equally melt both a resin component to be welded and a resin mounting board so as to be strongly and finely welded to each other by a method wherein spin welding is performed over heating of at least one contact part of either of the resin component or the resin mounting board the heat deformation temperature of which is higher than the other. CONSTITUTION:A resin component 1, which consists of a flange part 1a and an upright part 1b, is put on a resin mounting board 3, which is seated on a base stand 10 having a hole 1a. The resin component is covered from above with a rotary jig 12 so as to engage the engaging grooves 13a of an outer tube 13 with the engaging projections 2 of the flange part 1a of the component 1 to be welded. The jig 12 is rotated under the above-mentioned state and at the same time warm air is blasted from a warm air generating device 11 against the opposite surface 3a of the board 3. Because both the board and the component almost equally melt, even in the case that the heat deformation temperature of the board 3 is higher than that of the component 1, the fine and strong welding can be realized to each other. In case that the heat deformation temperature of the component 1 is higher than that of the board 3, the heating of the component may well be done.</p> |
