Abstract
Provided is a laser welding structure which may couple parts to each other by using a laser welding, and more particularly, a laser welding structure enabling laser welding of thermosetting resin including a glass fiber, the laser welding structure for the thermosetting resin including the glass fiber according to the present disclosure, and the method using the same, configured as described above, may provide the improved welding structure by coupling the parts made of the glass fiber-reinforced PPS material to each other by the laser welding.
Claims14
A laser welding structure for thermosetting resin including a glass fiber, which couples a transmission layer made of a laser beam transmission material and a non-transmission layer made of a non-transmission material to each other by laser welding, the structure comprising:
- the transmission layer made of a resin material including the glass fiber;
- and
- the non-transmission layer made of the resin material including the glass fiber and having one surface coupled to the other surface of the transmission layer,
- wherein the transmission layer through which a laser beam is transmitted has a thickness of 1.5 mm or less.
A laser welding structure for thermosetting resin including a glass fiber, which couples a transmission layer made of a laser beam transmission material and a non-transmission layer made of a non-transmission material to each other by laser welding, the structure comprising:
- the transmission layer made of a resin material including the glass fiber;
- and
- the non-transmission layer made of the resin material including the glass fiber and having one surface coupled to the other surface of the transmission layer,
- wherein the transmission layer has a thickness enabling a transmittance of a laser beam transmitted through the transmission layer to be 20% or more.
