Design Works Laser Welding Services
We are proud to offer Laser Welding Services using the Sweet Spot Resonator (SSR) from Rofin-Baasel, Inc. This style of laser is only approximately 10 years old. The technology is still revolutionizing the jewelry industry after 10 years, but is also opening up markets of opportunities in other industries. A unique advantage that jewelers have with this machine is that the geometry of laser welding jewelry items is often more complex than items in the majority of other industries. Jewelers are welding many metals and alloy combinations that have different welding requirements, they weld different thickness', and design features with various angles. All of these equate to a jeweler using this technology at a greater range of it's capabilities than what this technology is generally used for in other industries. Therefore, when a jeweler has become proficient on his of her own application they are usually well suited to accomplish welding for other industries, such as: Dental, Tool and Mold, Medical Device Manufacturing, Electronics, Scientific Research and Development, etc. etc. This technology is revolutionizing a lot more than just jewelry and we are ready to diversify into other applications rather than concentrating solely on jewelry.
New techniques and products are making previously difficult frames more
suitable for laser welding, such as: Titanium alloyed flex frames.

The SSR Results in Higher Quality Welding
One very important feature of producing a quality weld is the ability to accomplish adequate penetration and fusion at the lowest possible energy. This is especially evident when welding alloys that contain metals of various different melting temperatures, as well as other differing properties such as, resistance to oxidation while molten, heat conductivity, density, and reflective nature to light.
Nickel Alloy: Nickel alloy presents some challenges because Nickel oxidizes easily while heating in an oxygen environment. One would weld Nickel Alloys using an inert shield gas such as Argon. Using shield gas in combination with the lower total energy requirements offered by the SSR Welding results in less overall heating of the Nickel Alloy.
Solders, Zinc, Lead, Base Metals & Low-Melting Temperature Alloys: All of these metals and alloys easily burn and vaporize with too much energy; resulting in micro-porosity and brittleness in the weld seam. Achieving adequate penetration and fusing, into these metals and alloys, with lower total energy offered by the SSR risks less vaporization and burning of the metal, and gives more options and overall ability to successfully join these metals and alloys containing these metals.
Silver, Copper, Heat Conductive, and Reflective Metals: Silver and Copper are extremely heat conductive, as well as very reflective, (mirror like when polished), metals. Keep in mind that the laser is a beam of light that will have a tendency to reflect off of mirror like surfaces. Heat conductive metals tends to draw the energy of the laser into and throughout the piece rather than allowing the energy to stay localized at the seam to perform its welding function. Reflective and heat conductive metals require higher energy for welding to overcome these properties. Because of the SSR finer focusing, and more consistent distribution of energy, the heat conductive and reflective properties can be overcome at a lower total energy.
Platinum: Platinum has a high density requiring physical force that equates to relatively higher energy requirements. Again, because of the SSR finer focus and consistent distribution of energy, platinum can be welded with lower energy.
Heat Sensitive Items, Items with spring temper characteristics, or very small and thin items:All of these are at less risk of damage, change in spring temper, and easier to weld with finer focusing ability and lower energy characteristics of the SSR.
