From the idea to the design to the finished product.

Our welding technology according to your requirements.

Our internal fixture construction allows us to achieve the desired result as quickly as possible and to obtain an extremely precise and thus hygienically completely harmless joint.

01 TIG welding, MIG welding, MAG welding

Whether TIG, MIG or MAG welding, at Rieber we offer all common welding processes, each adapted to your needs and requirements. The process has a number of advantages over other fusion welding processes. In combination with TIG pulse welding and TIG AC welding, any material suitable for fusion welding can be joined.

TIG welding produces practically no welding spatter; the health risk from welding fumes is relatively low. A particular advantage of TIG welding is that it does not use a melting electrode. The addition of filler metal and the current intensity are therefore decoupled. The welder can optimally adjust his welding current to the welding task and only has to add as much filler metal as is required at the time. This makes the process particularly suitable for welding root passes and welding in constrained positions. Due to the relatively low and small-scale heat input, the welding distortion of the workpieces is lower than with other processes.Because of the high weld seam grades, the TIG process is preferably used where welding speeds are less important than quality requirements.In metal active gas welding (MAG), either pure CO2 or a mixed gas consisting of argon and small amounts of CO2 and O2 (Corgon) is used. Depending on their composition, the welding process (penetration, droplet size, spatter losses) can be actively influenced; in metal inert gas welding (MIG), argon is used as the noble gas, and less frequently the expensive noble gas helium. The MAG process is primarily used for steels, the MIG process preferably for non-ferrous metals.

02 Laser welding

Laser welding is mainly used for welding components that have to be joined with high weld seam quality and low thermal distortion. Rieber has specialised in welding the thinnest sheet thicknesses with process reliability.

03 Resistance welding

Here the stainless steel is heated by electrical energy until it melts. By pressing together during and after the current flow, resistance pressure welding produces the formation of an intimate joint.Rieber offers spot welding processes and roll seam welding processes.

Take advantage of one of the largest annealing furnaces in Germany.

01 Bright annealing

With one of the largest bright annealing furnaces in Germany, Rieber has the best possibility of producing large deep-drawn parts with extreme deformations. The advantage of bright annealing compared to conventional annealing is that stainless steel retains its gloss completely.

Working temperature: 1070 °C under inert gas atmosphere

Largest part dimension: 790 x 400 mm (W x H).

Flexible, three-dimensional and precise.

01 Laser cutting

State-of-the-art 3D lasers allow an extremely precise cutting edge, with a maximum working range of 4000 x 2000 x 900 mm (L x W x H), with a power of 3200 W.

02 Cutting tools

State-of-the-art EDM technology and TIN-coated tool parts enable difficult part contours and long service lives of the cutting tools.

Due to the high hygiene regulations in the canteen kitchen sector, Rieber has acquired a comprehensive range of surface finishes.

Whether stainless steel, nano-surface treated, coated, enamelled or electropolished, we have the right surface for every application.

02 Sandblasting Glass bead blasting

We have long-standing partnerships with suppliers for other surface finishing processes. Here, too, we can look back on decades of experience in sandblasting and glass bead blasting. Glass bead blasting densifies the surface, which also contributes to an increase in surface hardness and thus to an even longer durability. But the non-stick effect can also be increased by the targeted use of glass bead blasting. We use the sandblasting process to clean surfaces in order to coat them afterwards, for example.
