What Steigerwald Strahltechnik Gmbh does

Steigerwald Strahltechnik GmbH is a German specialty manufacturer of electron beam (EB) machines, headquartered in Maisach, Germany, and operating since 1952, when founder Dr. Karl-Heinz Steigerwald built the world's first electron beam machine. The company designs and produces chamber-based EB welding machines (EBOCAM®, EBOMOVE, EBOFLEX), continuous strip welding systems (EBOCONT®), high-speed perforation machines (EBOPULS), electron beam generators (EBOGEN, 3–60 kW with high-voltage technology up to 150 kV and beyond), as well as atmospheric welding (EBONOVA) and additive manufacturing (EBOADD) systems. Its process technology enables deep single-pass welds exceeding 100 mm with up to 95% beam energy utilization, more than 60% electrical-to-process energy conversion, and 'drilling on the fly' perforation at up to 3,000 holes per second across sheet thicknesses up to 7 mm with hole sizes from 30 µm to 1.2 mm.

The company serves enterprise customers in aerospace (ArianeGroup, Lufthansa Technik), turbomachinery, nuclear research (CERN, for beryllium vacuum chambers on the LHC upgrade with production from 2026 and installation during Long Shutdown 3 in 2027–2028), automotive, medical technology, rail, shipbuilding, defense, renewable energy, and industrial filtration, alongside research partners such as Fraunhofer IWU and TWI Cambridge. Sales are conducted via direct enterprise engagement with engineering and procurement teams, supported by an international sales service network spanning America, Europe, and Asia/Far East, and complemented by contract manufacturing and job-shop services delivered through sister company PTR Strahltechnik GmbH in Langenselbold. Steigerwald operates as part of the Global Beam Technologies (GBT) Group, a strategic operating parent that provides global reach and group-level resources; the company is privately held with no disclosed funding rounds and is currently led by Managing Directors Frank Schüßler, Dr. Johannes Franner, and Anton Kassewalder.

Broad incumbents

• Lincoln Electric Holdings: Global broad-line welding and cutting equipment manufacturer — competes in adjacent welding categories (arc, plasma, laser) that increasingly substitute for EB in mainstream industrial applications.
• EMAG Group: German machine tool manufacturer for metalworking (turning, milling, grinding, gear cutting) — broad incumbent serving overlapping automotive, aerospace, and turbomachinery customers as SST.
• TRUMPF: Global leader in industrial laser welding, cutting, and bending systems — broad incumbent that competes with SST where laser welding substitutes for EB welding in sheet-metal and automotive applications.

Direct peers

• pro-beam GmbH & Co. KGaA: German direct competitor specializing in electron beam welding and drilling systems, serving aerospace, automotive, and tooling customers — competes head-to-head with SST in chamber welding and EB generators.
• Sciaky, Inc. US-based direct competitor offering electron beam additive manufacturing (EBAM) and EB welding systems for aerospace, defense, and industrial markets — directly overlapping SST's EBOADD and EBOCAM product lines.
• ALD Vacuum Technologies: German manufacturer of electron beam and vacuum metallurgy equipment for aerospace, automotive, and specialty alloys — overlaps with SST in EB-based welding and surface-treatment applications.
• MLS Lichtenfels (formerly Linde + Wiemann): German electron beam systems integrator and job-shop operator serving automotive and industrial customers — competes directly with SST in EB welding services and equipment sales in the DACH region.
• Cambridge Vacuum Engineering (CVE): UK-based specialist in electron beam welding and vacuum brazing equipment for aerospace, nuclear, and automotive applications — directly competes with SST in high-precision EB chamber systems.

Others

• PTR Strahltechnik GmbH: Sister company within the GBT Group providing contract electron beam welding, drilling, and perforation job-shop services in Langenselbold, Germany — adjacent rather than competitive since it uses SST-built technology.
• Bodycote plc: Largest global provider of heat treatment and surface treatment services — adjacent service competitor to SST's surface-treatment and job-shop offerings, particularly for aerospace and automotive components.
