Laser Welding Technology

AGNOTEX laser welding systems’ capabilities span a wide range that includes thin, fragile or precision assemblies and pre-fabricated components that require welding near electronics or ceramic/glass components. Hermetic sealing utilizing sealed chamber glove box welding is also available.

Each project begins with our seasoned product engineers collaborating with your team for a project review. This enables us to provide the best solution using one of our many CO2, Nd:YAG, or Fiber laser systems and to create custom fixtures, tools and systems as needed.

From prototype to production, we can offer entirely customized tooling solutions to suit your project requirements. With virtually no dependence on third-party vendors for the design, building, and maintenance of tooling, AGNOTEX holds complete control over delivery lead times on your projects.


Advantages of Laser Welding

Laser-enabled welding provides unmatched advantages in intricate and thin-walled components. We utilize our state-of-the-art welding machines to weld dissimilar materials and a range of exotic materials. Laser Welding Systems are designed with the needs of the precision micro-welding and micro-cutting industry in mind, providing a level of accuracy and consistency previously unavailable. This is made possible due to the unique capabilities of the laser engine, including sub 0.5% pulse-to-pulse energy variation, /-0.5% CW power stability over time, single-mode beam quality and focused spot sizes down to 10μm. These features, coupled with close-loop power feedback, pulse profiling, high energy efficiency and no optical parts to align or calibrate, make our laser welding systems an attractive laser engine for practical shop floor environments.

Here are the major advantages of laser precision welding:

  • Less distortion on work pieces because metal is fused within a very small area at high speeds and welds that are consistent and reliable.

  • Higher production rates, thus saving you money.

  • Little or no joint preparation required for this type of welding, saving additional time and money.

  • We offer narrow, precision weld beads with excellent cosmetic appearance, to a high degree of accuracy.

  • Laser welding allows for joining dissimilar metals with no filler metal.

  • laser welding systems do not exhibit the shortcomings in output power, spot size and focal point variations caused by thermal effects on the glass rods of traditional YAG laser welders.

  • laser welders offer true welding consistency at all power levels, across all pulse sequences and during the entire lifetime of the laser. The laser parameters remain predictable and consistent. The reason for this is that the generation and transport of the laser beam to the work-piece takes place entirely within the confines of a single mode fiber. The beam shaping provided by this fiber neither degrades over time nor changes with laser power - this also makes the laser physically robust and stable, thus suitable for the most challenging of industrial environments.

  • Additional advantages of laser welders are the small spot size and high beam quality that translate to high irradiance at the focal plain. Workstations equipped with laser welders can produce better results at lower power levels. The focused beam of energy consistently affects a very small area of metal, providing the benefit of very little heat generated around the weld point.

  • High quality, precision laser welding can be performed extremely close (0.1mm) to the most complicated and intricate component parts.

  • laser welding system applications are not limited to just welding. Cutting of medical grade steels and wire end preparation for medical components are both effectively produced with the fiber welding systems.

  • From an economics standpoint, the consistent and improved laser welding performance reduces scrap and generates faster production throughput, resulting in a lower cost of ownership and improved laser up-times.

  • Laser welding is a proven joining method for a variety of today’s metals and alloys. However, this highly sophisticated process is best left to the experts. At AGNOTEX, we have successfully used our lasers to weld various grades of carbon steels, nickel alloys, stainless steels, titanium alloys and super alloys.

  • That’s precisely why enterprises worldwide consider laser welding to be a viable alternative to TIG welding, EB welding, resistance welding, brazing, silver soldering and adhesive bonding. Our process is particularly ideal for high production volumes associated with fully-automated or semi-automated tooling applications.

  • AGNOTEX also offers a variety of post processing options to your welded assemblies such as micro-abrasive blasting, electro-polishing and passivation.

These financial and performance advantages mean that laser technology is now frequently chosen as an upgrade over conventional flash-lamp pumped solid state lasers, or even DPSS laser technology in many other laser-based manufacturing segments. In addition, a small footprint and fast ROI open up markets that were previously out of reach for some laser welding applications.
