The Digital Wolfram Expert System makes quality measurable and manageable: analyze welding processes in real time, support operators directly on the job – this is the future of manufacturing.
For over 110 years, Wolfram Industrie has specialized in producing tungsten for welding technology. Our products and services are still market leaders today. With "Digital Wolfram" we carry this tradition forward and add a digital assistance system for uncompromising manufacturing quality.
Digitalization in welding has long been seen as difficult to implement. Especially in TIG welding, solutions were mostly limited to collecting and storing data – leaving a critical gap: the ability to detect process deviations early or even correct them automatically. With the Digital Wolfram Expert System, real-time monitoring, evaluation, and autonomous intervention become available in a truly integrated way.
Our goal is intuitive assistance systems that make welding processes more transparent, safer, and more efficient – without replacing the welder’s expertise. We believe people remain irreplaceable. Quick perception is a strength, but limited attention spans carry risks. This is where our system helps – boosting productivity and quality while reducing workload.
An optional extension is a spectrometer developed specifically for arc welding. It enables both qualitative and quantitative analysis of plasma composition – directly during welding and in real time.
The device can be integrated into the Digital Wolfram System or operated as a standalone measurement solution. Data is captured via a fiber optic cable (up to 80 m), making it suitable for both stationary and mobile welding applications.
The analysis algorithms were developed fully in-house and can be customized. Arc spectrometry is already setting new standards in process monitoring.
The system has already been successfully used in three pilot projects and will be presented in a new version at SCHWEISSEN & SCHNEIDEN 2025.
Typical applications:
Wolfram Industrie supports customers from technical consulting and parameter selection through to full commissioning – including training, documentation, and ongoing support. Retrofitting sensors and software extensions is straightforward and part of the overall concept.
For Wolfram Industrie, digitalization is not just technology – it is a partnership. That is why we support our customers at every stage – from the first conversation to day-to-day operation.
Already in the planning phase, we help with parameter selection, technical design, and integration into existing structures.
For system introduction we provide targeted training for operators, technicians, and quality managers – practical, application-oriented, and tailored to specific use cases. Welding and parameter tests can be carried out in our welding lab at any time without affecting production.
Our promise: solutions that not only work but deliver lasting value and adapt flexibly to changing conditions.
"Digital Wolfram" is a digital assistance system for manual and automated TIG welding.
It combines three key elements of digital process control:
The welder is relieved but stays in control – supported by a system that only intervenes when necessary.
