Reis Robotics' laser hybrid welding system with new welding optics from Reis Lasertec is finding real-world use.
Laser hybrid welding combines the advantages of the two methods – laser welding and gas metal arc welding – in a common process. The essential advantages include very high welding speed, together with minimal distortion and small heat affected zone, as well as very good metallurgical and mechanical characteristics of the weld seams. Thus this method is suited for a multitude of applications. It is already used for welding of comparatively thin-walled structure components in automotive construction. In further examples, customers of Reis Robotics also apply the technology for manufacturing of concrete pumps and jibs for mobile cranes. Here, high-tensile steels are processed, whereas other production methods would cause an increased expenditure, such as extra preheating in order to prevent distortion.
Further it can be applied in rail vehicle construction as well as in general steel construction such as the production of bridge elements and tank production.
The rising demand for this comparatively new joining technology was the trigger for the development of optical components by Reis Lasertec. Thus, integrated beam guidance in the robot arm, which has been patented by Reis Robotics, now can also be used for this technology.
Reis also contributes to the development in the Laser Hybrid Welding field by having the possibility of performing in-house trials for all applications. For this purpose Reis Robotics has invested in the expansion of the laser laboratory in the technical laboratory. Now, since the middle of this year there is the new laser robot RV60-6-FT with integrated beam guidance for laser power up to 20 kW. In combination with the hybrid welding optics MWO54-Hybrid and a new 8kW laser, this equipment represents the current state-of-the-art.
Laser Hybrid Welding is trend-setting in the field of joining technology. Reis Robotics thus will present this technology as a focal point at the fair Schweißen+Schneiden in Essen, Germany, hall 2.0, booth B101 from 16 to 21 September 16 - September 21, 2013.
