(1) The position of the weldment must be very precise and must be within the focus of the laser beam.
(2) When the fixture is to be used with a fixture, it must be ensured that the final position of the weldment is aligned with the weld point that the laser beam will impact.
(3) The maximum weldable thickness is limited by the penetration of the workpiece with a thickness of more than 19 mm. The laser welding machine is not suitable for use on the production line.
(4) High reflectivity and high thermal conductivity materials such as aluminum, copper and their alloys, etc., the weldability will be changed by the laser.
(5) When performing medium-to-high-energy laser beam welding, a plasma controller is used to drive out the ionized gas around the molten pool to ensure re-emergence of the weld bead.
(6) The energy conversion efficiency is too low, usually less than 10%.
(7) The weld bead is rapidly solidified and may have pores and embrittlement concerns.
(8) The equipment is expensive.
