Aerospace applications require highly reliable and precise welding of components subjected to extreme conditions. Micro laser welding is used to join parts in aircraft and spacecraft, including sensors, actuators, and structural components, where accuracy and strength are paramount.
Sensor Technology
The technology is also used for welding thermal elements, measuring sensors, and pressure membranes. Micro laser welding enables the placement of seam welds adjacent to temperature and vibration-sensitive electronic components, as well as welding in the membranes of pressure sensors, where precision and minimal heat impact are crucial.
Key Advantages
Precise Heat Application
Micro laser welding offers highly controlled heat application, with short-duration energy transfer that is localized and precise. This focused approach minimizes the heat-affected zone, reducing the risk of distortion and preserving the integrity of the components.
Narrow Seams
The technology ensures narrow seams with minimal angular distortion and transverse shrinkage. This precision is crucial for maintaining the structural and functional integrity of small components, particularly in applications where tight tolerances are required.
Economic Efficiency
Micro laser welding is a cost-effective technique due to its high welding speed and productivity. The ability to achieve precise welds without the need for additional filler materials or extensive post-weld processing contributes to reduced production costs. Furthermore, the technique supports alternative design options that can further minimize material wastage and overall expenses.
Material Optimization
One of the standout features of micro laser welding is its versatility with a wide range of materials. It accommodates various material types and combinations, allowing for optimization based on specific local requirements. This flexibility is particularly advantageous in industries that require the welding of dissimilar materials or complex geometries.
