HBS Bolzenschweiss-Systeme GmbH & Co. KG

What HBS Bolzenschweiss-Systeme GmbH & Co. KG does

HBS Bolzenschweiss-Systeme GmbH & Co. KG is a German medium-sized industrial manufacturer founded in 1984 and headquartered in Dachau, Bavaria. The company designs, develops, and manufactures stud welding (Bolzenschweissen) systems, covering four core process technologies: capacitor discharge (CD), drawn arc (ARC), short cycle (SC), and insulation (ISO). Its product portfolio spans manual devices (Pegasar, Visar, CDi series), semi-automatic systems, and fully automated CNC welding machines (CPW, MPW series), complemented by welding guns, accessories, welding elements (studs, pins, nuts), and service offerings including repair, training, and rental.

The company operates a vertically integrated hardware business with proprietary inverter technology operating at 30 kHz for process regulation, in-situ process control for real-time welding monitoring, and the world's first battery-powered stud welding system (Pegasar 500 Accu) delivering up to 400 welds per charge. Multiple worldwide patents protect innovations across battery-powered welding, rotating arc (MARC), and process control. Approximately half of production is exported to customers in over 70 countries, served through direct field sales from Dachau and a network of certified dealers and distribution partners (including Multiweld and Welding Company in Kazakhstan). Notable end-use applications include HVAC insulation fastening, sheet metal fabrication for switchboard cabinets and medical equipment, steel construction and shipbuilding, petrochemical fire-resistant insulation, and automotive trim fastening.

HBS generates revenue primarily through B2B hardware sales of welding units, welding guns, and consumable welding elements, supplemented by professional services (repair, training, rental). Pricing is quote-based with a €100 minimum order value and a €50 handling surcharge below that threshold. The company was acquired by the Peiseler Group (backed by publicly listed German mid-market investor INDUS Holding AG) in January 2025 and now operates as a sister company to Köster & Co. GmbH (KÖCO) within that group. HBS holds ISO 9001:2015 certification verified by TÜV Süd and operates as a climate-neutral company.
