Laser welding provides a high-performance process for joining materials with various thicknesses in a wide range of modes. Among the main advantages – are high productivity, accuracy, and stability of the heating spot trajectory. High energy densities provide deep penetration and at the same time narrow heat-affected zone as well as minimal deformation of welded parts.
Modern laser complexes can significantly expand the technological capabilities of welding processes. At the same time, traditional welding methods either do not use beam shapes or often employ static beam shapes, limiting their adaptability and precision. However, by harnessing dynamic beam shapes, such as variable spot sizes, beam shapes, frequencies, and trajectories, researchers can achieve unparalleled control overheat input, penetration depth, and weld bead morphology.
The new laser laboratory at the Israel Institute of Materials Manufacturing Technologies, created as part of the LAMP consortium, is equipped with the most powerful and advanced laser in Israel in the field of material processing. Laser-based on Coherent Beam Combining (CBC) technology with wavelength 1064 nm and 14kW power.
The properties and features of a 14-kilowatt optical phase array (OPA) laser will be described during the seminar. We will also showcase practical examples of its application in the Israeli industry. This includes demonstrations of welding of aluminum, armor steels, and various cases of dissimilar welding.
