Due to their outstanding characteristics, laser welding machines have become an indispensable production tool in medical technology.
Whether in the production of implant-systems, or the manufacture of surgical instruments or endoscopes, the particular properties of laser welding joints and seams are recognized here for their full validity:
- narrow welding seams with high strength
- gas tight bonding of seams
- corrosion-resistent
- porous free with smooth surface, suitable for high-temperature-sterilisation
- biocompatibility in accordance with the basis material
The weldings can be carried out with or without filler wires, according to the properties of the basis material. Neither the biocompatibility, the strength, nor the porous-free nature of the materials are affected.
