Abstract
A method for laser welding of non-transmissive composite materials includes: forming an energy channel having an end opening and extending through a first part made of a first material; and welding a second part made of a second material to the first part via laser heating of the materials of the first and second parts proximate to the end opening of the energy channel such that the materials of the first and second parts fuse to form a weld nugget, attaching the first part to the second part.

A method for laser welding of non-transmissive composite materials, comprising:
- forming an energy channel having an end opening and extending through a first part made of a first material;
- and
- welding a second part made of a second material to the first part via laser heating of the materials of the first and second parts proximate to the end opening of the energy channel such that the materials of the first and second parts fuse to form a weld nugget, attaching the first part to the second part.
A method for laser welding of non-transmissive composite materials, comprising:
- forming an energy channel extending through a first part and having an end opening;
- positioning the first part relative to a second part such that a first surface of the first part is proximate to a second surface of the second part adjacent to the end opening of the energy channel;
- and
- welding the second part to the first part via laser heating of the first and second parts proximate to the end opening of the energy channel such that the first and second parts fuse to form a weld nugget;
- wherein the first part is made of a first material that is non-transmissive to laser energy and includes a thermoplastic material;
- and
- wherein the second part is made of a second material that includes a thermoplastic material.
A method for laser welding of non-transmissive composite materials, comprising:
- forming an energy channel extending through a first part and having an end opening;
- placing an insert between a first surface of the first part and a second surface of a second part;
- and
- welding the second part to the first part via laser heating of the insert, the first part, and the second part proximate to the end opening of the energy channel such that at least one weld nugget is formed, attaching the first part to the second part;
- wherein the first part is made of a first material that is non-transmissive to laser energy and includes a thermoplastic material;
- and
- wherein the second part is made of a second material that includes a thermoplastic material.
