(1) The weld position needs to be very precise and must be within the focus range of the laser beam.
(2) when the welding parts need to use the clamping fixture, it is necessary to ensure that the final position of the weld needs to be aligned with the laser beam will impact the solder point.
(3) The maximum weldable thickness is limited by the penetration thickness of the workpiece far more than 19mm, the production line is not suitable for the use of laser welding machine.
(4) High reflectivity and high thermal conductivity materials such as aluminum, copper and its alloys, welding will be changed by laser.
(5) When welding a laser beam with medium energy to high energy, a plasma controller is used to remove the ionized gas around the melting pool to ensure the re-emergence of the weld.
(6) Energy conversion efficiency is too low, usually less than 10%.
(7) Rapid solidification of the weld path, may have the concern of stomata and brittleness. (8) Expensive equipment.
