What Dalex does

DALEX Automation & Welding GmbH is a privately-held German manufacturer of resistance welding technology headquartered in Wissen, Germany, founded in 1911 and operating for over a century. The company develops, designs, and manufactures standard and custom welding machines, robot welding guns, hand-held welding guns, and — uniquely within the resistance welding industry — its own medium-frequency (MF) and AC welding transformers in-house. Its product portfolio spans six standard categories (industrial machines, trade machines, robot welding guns, hand-held welding guns, MF transformers, and accessories) plus custom special machines and automated fabrication cells, which account for approximately 60% of annual production. Proprietary technology includes the EPS (Electro-Pneumatic Welding Drive) for consistent force delivery, a 2-stage MF transformer topology capable of generating up to 50V to weld coated and dissimilar materials, and a portfolio of 24 standardized robot welding gun variants (XZ/CZ series) conforming to Euro norms.\n\nDALEX serves a global customer base primarily in the automotive OEM and Tier-1/Tier-2 supplier segment, with named enterprise customers including BMW, Volkswagen, Ford, General Motors, Daimler/Mercedes-Benz, and Audi, plus non-automotive enterprise customers such as Husqvarna. Additional verticals include household appliances, industrial equipment, commercial vehicles, aerospace, and trade/craft businesses. The company is the only resistance welding equipment manufacturer certified to the VDA 6.4 automotive standard, in addition to DIN EN ISO 9001:2015 and ISO 14001:2015, supporting qualification in the most demanding automotive supply chains.\n\nThe business model is hardware sales-driven, supplemented by a full-service offering covering consultation, project planning, machine construction, training, and after-sales service and maintenance. DALEX sells primarily through a direct technical sales force backed by an international network of sales representatives covering over 40 countries, with demand generation reinforced by an active trade fair presence at EuroBlech, BEIJING ESSEN WELDING & CUTTING, and ELMIA Svets. The company manufactures all equipment at its Wissen facility, which includes an in-house Technology Center for prototype welding, testing, and customer demonstrations. In December 2022, DALEX acquired AUGENSTEIN to broaden its automation technology capabilities.
