The HLx Series mechanized laser-welding system uses laser only, laser with cold wire fill or hybrid laser arc welding in a 2-D gantry, 3-D robotic or custom mechanical with closed-loop weld process control. The manufacturer says hybrid laser arc welding combines the deep-weld penetration and low-heat input associated with laser welding with the power efficiency and superior gap tolerance of gas metal arc welding to create a new alternative. The company also claims that deep penetration and fast weld speeds of laser welding reduce heat infusion into the part and reduce the associated distortion that causes plates to buckle and warp. A key component of the system is a patented closed-loop control that allows the system to monitor the weld joint in real time and modify the process to accommodate a joint mismatch.
