ABSTRACT:
A laser welding technique for joining two parts together, the parts having contacting faces which define an interfacial region. One part is permeable to a laser beam directed toward and focused on the interfacial region, the face of the other part having light-disruptive characteristics whereby when the beam impinges thereon, multiple internal reflections are produced within the interfacial region which trap the energy of the beam to generate sufficient heat to cause the parts to superficially melt and fuse.
