Abstract: Laser welding is used to attach a polyolefin air induction component to an elastomeric hose member. One of the hose or induction component includes a portion that is made from a transparent material. In one example, the hose includes a hose end portion that is formed from a transparent material. The transparent material is then positioned in an overlapping relationship to a tube received within an opening in the induction component, which acts as an absorbing component. Contour through transmission welding is used to generate a laser beam that passes through the transparent material, heats the absorbing component, which in turn heats the transparent material and forms a laser weld.
