Claim Text:
1. A laser welding method for joining work pieces in an eye-safe environment, the method comprising: providing a laser module including a collimator, a delivery fiber, a linear drive, and a housing, the collimator configured to receive the delivery fiber for delivering laser radiation to a work piece, the housing configured to provide an exit slit for the laser radiation such that the laser radiation may only exit from said exit slit and the linear drive is configured to move the housing and thereby the exit slit in proximity to a desired welding location; providing a pressure piece located proximate to the exit slit and configured to provide a closed circuit control of emission of laser radiation when actuated; abutting the pressure piece to a work piece sufficient to actuate the pressure piece and close the circuit; and providing laser radiation to the work pieces sufficient to create a weld while maintaining an eye-safe environment.
