Plasma Technology continues to find new uses for the Watson XRF spectrometer. Watson™ is helping surface engineering companies salvage and recycle metal powders they use in coatings. So not only does Watson™ remove risk in QC/QA manufacturing but it also is now generating new revenue.
Plasma Technology performs surface coating services that draw from a coating library of over 300 different coating recipes that can be applied using eight different techniques including High Velocity Oxy-Fuel Coating (HVOF), Plasma Coating, Combustion Coating, and Wire Arc Coating. The company salvages and recycles the metal powders they use in their coating that do not bond with the customer’s parts. The company employs a set of processes to make sure that technicians do not mix high value metals with lower value metals as this significantly reduces the amount a recycler will offer for the salvage.
Technicians can use a portable XRF spectrometer to verify the actual metal composition of a salvage container to make sure it is the appropriate grade for the scrap metal that will be stored in it. This provides a positive method for detecting and avoiding mismatching elements to be placed in the same storage container that could poison or lower the value of the material to be recycled.
Plasma Technology, Inc. (PTI) provides surface engineering services for aerospace and other application spaces. The company applies coatings to parts it receives from its customers. It is critical that the company can positively verify that a part’s actual material composition matches the coating that will be applied to it. Watson™ verifies material compositions matching surface coatings for aerospace industry.

It is critical that the company can positively verify that a part’s actual material composition matches the coating that will be applied to it. Using the XRF spectrometer provides a non-destructive method to ensure that there is no mismatch between the materials in the coating to be applied and the actual material composition of the part.
The company is able to use the XRF spectrometer to verify raw stock, powder stock, and customer parts to their certification when each is received. The portable XRF spectrometer enables repeated material verification to take place as parts move from one part of the organization to another helping to detect if and when in-process mismatches occur.
Adopting XRF spectrometry enabled Watson™ XRF analyzers Warmelin Precision Engineering to use Watson™ XRF analyzers to catch problems in metal stock at the receiving dock. Warmelin discovered another reason for using the XRF spectrometer because it generated enthusiasm in their customers for a fast, non-destructive, and low-cost method to explicitly verify the materials of components before shipping them to aerospace customers.
Warmelin, also known as WPP, uses the latest CNC milling and turning technologies (including three 6 Axis machining centers, featuring 138″ x 40″ x 28″ travels, 12,000 RPM and 75HP spindles) to deliver complex manufacturing and assemblies for their aerospace customers using common and exotic metals such as inconel, titanium, and hastelloy. Thin-walled machining is one of their core competencies.

Added benefit: Watson enables material verification to avoid in-process mis-matches enabling cost recovery via faster troubleshooting.
The company discovered an unexpected benefit of using XRF spectrometry. Because the company proactively invests in continuous process improvement, in cooperation with its customers and suppliers, production processes are often subject to transition issues. These issues are likeliest to arise at the interfaces between different organizations both within and without the company.
Watson™ XRF spectrometer enable repeated material verification to take place as parts move from one organization to another by helping to detect if and when in-process mismatches occur. This makes it a powerful troubleshooting tool when tracking down and solving root causes of a mismatch.
Electron beam welding and laser welding are ideal technologies when you need precision welds with small, delicate, and complex components. Both technologies use a low heat input, can work in a narrow weld zone, produce a small, localized heat affected zone, and produce clean welds that do not require any finishing. Electron beam welding can be used with almost all metals, including stainless steels, refractory metals, and flammable metals. It is critical that the metals on each side of the weld are positively identified to ensure the proper processes and precautions are in place for complex precision welding.
The electron beam welding process is used to perform welds on a variety of dissimilar metal combinations. X-ray fluorescence (XRF) spectrometry is a non-invasive, non-destructive testing process that enables companies to positively identify and verify the chemical composition of metal alloys. XRF measurements enable companies to confirm that the source materials from their suppliers are correct before starting to work with them, and to positively verify that their product consists of the correct materials before shipping it to the customer.
With the commercial release of Tribogenics’ triboluminescence technology that nearly halves the cost of using XRF technology without sacrificing capability and mobility, electron beam welding shops, such as Electron Beam Engineering (EBE), are realizing the benefits of incorporating XRF spectrometry into their daily processes and procedures.
EBE provides precision electron beam welding and laser welding services throughout the United States and Europe for a variety of applications including aerospace, automotive, defense, medical, and sensors for high temperature/pressure environments. The company is incorporating the Watson™ XRF spectrometer for formal positive material identification, including supporting first and last article sampling and testing. EBE verifies whether the thickness of materials, such as carbon content, is just outside its tolerance level. Watson™ permits the use of a non-destructive testing method.
EBE also uses Watson™ to examine welds that look out of spec. This inspection is an important insurance because even though certification mismatches are rare, they are not zero. In those cases where EBE is a sole source for a component process, Watson™ helps incorporate additional precautions, especially those that address sources of disruptions. For example, Watson™ permits the technician to verify with a test piece to know that the welder is performing the weld correctly before moving onto the rest of the batch.
Until recently, like many other companies, EBE knew it could benefit from using XRF in their processes, but the costs were too high to use it. Tribogenics’ Watson XRF spectrometers are available to own for approximately half the cost of conventional hand held XRF spectrometers. Additionally, Watson™ XRF measurements can be as fast as 10 seconds for aluminum alloys and approximately 30 seconds for steel alloys.
