Laser welding is a reliable method for joining multiple medical device components in butt or lap joint configurations.


Many of our customers have a need for CNC Laser Micro Welding. To accommodate our customers, we utilize a type of laser called an Nd:YAG laser. It’s named for the synthetic transparent crystal material that is at the core of the laser; triply ionized neodymium (Nd3) and yttrium aluminum garnet (YAG).

Marshall has extensive experience utilizing CNC laser welding in joining machined medical components. In many cases, CNC laser welding is the preferred method of assemble, because no new material is introduced into the process. It is also fast, offering high productivity. Excess heat doesn’t accumulate into the components being welded because the beam is precisely focused at the joint being welded. Because the laser is CNC driven, it is very accurate and repeatable.

Laser welding introduces a minimal amount of heat to the material, crediting the process with maximizing the depth of the weld. The minimized heat affected zone (HAZ), also contributes to minimized part distortion.

Often efficiencies can be gained by laser welding two or more components together rather than machining one larger component out of a single piece of raw material. For example, it might be a better proposition to butt-weld a tube to the end of a rod rather than machining a deep axial hole into the end of a solid rod. The optimal time to take advantage of CNC laser welding options is in the design stage of a component or assembly.
