Products within the medical industry require the highest levels of precision and have to meet the highest quality demands. The size of many medical devices and products is continually decreasing, and lasers are perfectly suited for creating equally minute weld seams. Even in complicated areas, laser weld spots and seams can easily be generated to provide sterile surfaces with no post-processing.
The high weld integrity achieved with laser welded joints makes them suited for high-temperature sterilisation, and the limited heat affected area ensures that surrounding material is not annealed and weakened. A wide variety of metals can be laser welded, including alloys, and there are no filler materials added during the processing. This removes any potential biocompatibility issues for products such as implants.
Just a few examples of medical devices that can be created with the aid of laser welding include:
