Providing the Highest Quality Laser Welding Solutions

Cadence offers consistently precise, reliable, high-quality welds for a wide range of materials including precision laser welding for medical device and aerospace components and subassemblies, as well as many other applications. Our experience and expertise, combined with the latest technologies, allows us to perform precise laser welding at great speed and efficiency, as well as repeatability. Some of the advantages of laser welding over traditional welding techniques include:Laser welding for medical device components.

Advantages of laser welding

  • More consistent, reliable joints
  • Small heat-affected zone (HAZ)
  • Deep penetration of precise narrow welds
  • Narrow weld profile
  • Low heat input
  • Minimum part distortion
  • No to minimal secondary processing
  • High repeatability
  • Significantly faster weld rates

Cadence's laser welding processes are capable of joining similar metals, as well as dissimilar metals via spot or seam welds. Thus resulting in welds that provide excellent strength and visual appearance. Our laser welding capabilities feature a wide variety of innovations and unique technological characteristics, including:

Unique technological characteristics

  • Micro-weld technology - uses smallest weld spot diameters for finest applications
  • Dual-beam technology - the capability to weld on opposite sides of a part at the same time
  • Double-closed loop power control - Pulse-to-pulse stability of less than 1% yields better joints and less variation part-to-part
  • 5-axis control for the most complex laser-welding requirements
  • Cleanroom laser welding, if needed

Advanced Laser WeldingOur Advanced Welding LabTM provides endless possibilities for all of your most advanced welding needs.


Conventional vs. Fiber Optic. The choice of laser is determined by material type and thickness, cycle time and weld penetration requirements. There are two types of beam delivery options commonly used when welding: conventional beam delivery and fiber optic cable. Conventional beam delivery, suitable for both Nd:YAG and CO2 lasers, is ideal for 5-axis cutting positioning systems where flexibility and movement of the machine axes cannot be hindered or constrained.


Fiber optic delivery is suitable only for welding with Nd:YAG lasers. An advantage of using a fiber for welding is its ability to mount an end effector on a robot, creating a very flexible, low-cost platform for welding large complex 3D parts. 3d laser cutting services are also available along with 5-axis cutting.


Precision laser welding for complex parts.These benefits are a result of using a small focus spot size, 0.001″ to .04″, appropriate gas shielding, well-engineered joint design, and ensuring repeatable fit up of parts. Successful laser welding is also dependent on controlling process variables, such as selecting the correct type of laser for the material and thickness. Reflectivity and conductivity will affect weld quality. Part preparation and cleanliness is also very important, as any contamination in the joint can produce voids and porosity in the weld. The correct combination of these elements is critical for achieving optimum laser welds.
