For more than 100 years, Wolfram Industrie has been a regionally rooted technology company with sites in Bavaria and Switzerland. Despite the trend of relocating production abroad, the family-owned company remains committed to Nußdorf, Dachau and Winterthur, where more than 120 employees manufacture high-precision tungsten and molybdenum products for demanding industries. For this commitment to its locations, combined with sustainable investments and social engagement, the company received the Bavarian SME Award (Bayerischer Mittelstandspreis) in 2024.

Although individual measured values such as current, voltage and welding speed are already recorded in welding technology, process control still depends on the individual know-how of the welder. The welder's ability to react flexibly to tolerances in the weld joint through a combination of visual pattern recognition and acoustic perception still surpasses the potential of machine systems. To further automate welding, the intuition that welders have forged over many years of experience must be translated into logical language. But how? An article by Matthias Schaffitz, application engineer at Wolfram Industrie.

On average, around 50 percent of the effort in TIG welding goes into downstream inspection and rework. With higher quality requirements, the share of these work steps quickly rises to two thirds of the production process, as tighter inspection cycles and more complex repair welds may be required.
