Laser Welding of Large-Format Assemblies
Particle-free welding is required for various products in the automotive and household appliance industries, as well as in medical technology. Particle-free joining of large-format plastic parts with complex weld seams still poses a challenge. This is the point at which Branson Ultraschall, Dietzenbach, Germany, starts with a series GLX-3 laser welding machine. It is based on the company’s patented "Simultaneous Through-transmission Infrared (STTIr)" process, with which the weld seam can be simultaneously and uniformly heated, shortening cycle times and in particular compensating for component tolerances – according to the manufacturer an advantage compared to other radiation strategies, such as quasi-simultaneous welding. The simultaneous heating of the weld seam implies a seam thickness, such that tolerances of large-format parts can be compensated.
The GLX-3 welding machine was developed for large-format parts that require more laser performance and clamping force. The system has a servo-motor driven lifting table, which can receive molds with one or more cavities with a total weight of 500 kg. An integrated automatic mold changing systems permits a rapid mold exchange. In addition, the welding machine has four power steps (1250 W, 1500 W, 1750 W and 2000 W). The safety PLC for controlling the functions, and the safety devices of the machine are performed by the Branson Logic Control System. This makes automated control of the functions of the lift table, door and die possible, so that the weld cycle times can be reduced while simultaneously ensuring the process reliability.
