Abstract
A protrusion on a first member made of synthetic resin wherein a laser beam is applied to a side surface of the protrusion in a state in which a top surface of the protrusion of the first member is abutted against a second member made of synthetic resin, so as to melt at least the entire top surface of the protrusion and melt a portion of the second member in contact with the protrusion by heat of the melted top surface of the protrusion, followed by solidification of the melted portions, whereby the first member and the second member are welded together.
Claims9
A synthetic resin member welding method for welding together a first member made of synthetic resin and a second member made of synthetic resin, the method comprising:
- providing a protrusion on the first member;
- and
- applying a laser beam to a side surface of the protrusion while a top surface of the protrusion of the first member is abutted against the second member to melt at least the entire top surface of the protrusion and melt a portion of the second member, the portion being in contact with the top surface, followed by solidification of the melted portions, whereby the first member and the second member are welded together, wherein
- the first member and the second member are the same synthetic resin material,
- the first member and the second member are not transparent to the laser beam, and
- a path of the laser beam does not intersect the second member at the melt portion of the second member.
