METHOD FOR WELDING SYNTHETIC RESIN MEMBER
Document Type and Number:
WIPO Patent Application WO/2019/035442
Kind Code:
A1
Abstract:
Projections 12 are provided in advance on a first member 10, which is made of a synthetic resin. In a state in which the top surfaces of the projections 12 of the first member 10 are abutted against a second member 20, which is made of a synthetic resin, a laser beam L is radiated onto side surfaces of the projections 12 to melt at least the entire top surfaces of the projections 12, and portions of the second member 20 in contact with the projections 12 are melted by the heat of the melted top surfaces of the projections 12. Then, the melted portions are cured to weld together the first member 10 and the second member 20.
