About Us
JOSCH Strahlschweißtechnik GmbH specializes in electron beam welding (EBW) and electron beam hardening. Since 1998, the company has developed, manufactured, and inspected single parts through medium-sized series for industrial customers across the entire DACH region. Four EB systems process components from 50 g to 5,000 kg with diameters up to 2,500 mm and weld depths up to 100 mm in a single pass; the vacuum processes enable low-distortion welds with a minimal heat-affected zone. Materials processed include titanium, copper, aluminum, nickel-based alloys, stainless steels, and special materials such as molybdenum, tantalum, and platinum, including combinations that can hardly be joined using conventional methods. In addition to manufacturing, JOSCH offers weldability consulting as early as the design phase as well as certified inspection procedures in-house. Customer industries include aerospace, mechanical engineering, and medical technology.

Materials & Processes
Titanium
Lightweight, strong high-performance material for aerospace and medical technology, also combinable with special materials.
Copper
High thermal conductivity, e.g. for cooling plates; combinations such as copper-steel are also possible.
Aluminum
Lightweight material well suited to EB welding with minimal distortion thanks to the vacuum process.
Nickel-based alloys
For components exposed to high temperatures and corrosion in mechanical and plant engineering.
Stainless steels
Corrosion-resistant steels for precise, safety-critical welded joints.
Special materials (molybdenum, tantalum, platinum)
Refractory and precious metals for special applications, also in combinations such as platinum-titanium.
Electron beam welding
Fusion welding in a vacuum with weld depths up to 100 mm, low distortion, and narrow weld seams.
Electron beam hardening
Targeted surface layer hardening with hardening depths up to 1.5 mm for highly stressed, complex components.
