Laser Micro Welding

Laser micro welding utilizes the high speed and accuracy of Mundt systems to join two materials with precisely controlled weld penetration. As the industrial market needs grow and become more complex, laser-processing techniques must expand. Mundt has the technology to provide sub-micron accuracies for the production of a prototype through high production runs. The company has the capability to process products from simple two-dimensional parts through to the most complex shaped parts using multi-axis machining. Heat in a laser weld is highly focused to allow welding with less total heat input than conventional methods. This permits the welding of heat sensitive parts without any damage. Low heat input, high welding speeds and the ability to control quality during the process makes laser welding a mainstay in advanced manufacturing. Efficient production processes of complex parts are made possible with the use of laser technology.
