Welding and joining up to 10 t per part

Individual parts become assemblies: we manufacture welded structures up to 14 × 3 × 3.5 m and 10 tonnes per part — by hand or on three robotic welding stations, certified to EN 1090-2 EXC2 and DIN EN ISO 3834-2.

Welding and joining — documented to standard

August Bertrams GmbH manufactures welded assemblies up to a size of 14 × 3 × 3.5 m and a maximum weight of 10 tonnes per part — in all weldable materials. We use MAG, MIG and TIG welding as well as spot, stud and resistance welding.

For load-bearing steel components we are certified to EN 1090-2:2018, execution class EXC2; our welding quality requirements meet DIN EN ISO 3834-2. Both certificates are available in the download area — exactly the documentation your purchasing department and your auditors want to see.

Robotic welding: series quality, reproducible

Three robotic welding stations handle recurring assemblies — with consistent seam quality across the entire series.

Everything for the assembly from a single source

Blanking, punching, laser cutting and bending of the individual parts happen in the same plant as the welding — positional tolerances and deadlines stay in one pair of hands. After joining, the assembly is coated on request (e-coat, powder or galvanized) and delivered ready to install.

Frequently asked questions about welding

Which welding processes does Bertrams use?

MAG, MIG and TIG welding as well as spot, stud and resistance welding — by hand or on three robotic welding stations, depending on the assembly and quantity.

How large may a welded assembly be?

Up to 14 × 3 × 3.5 m at a maximum of 10 tonnes per part. Robotic welding is possible up to 12 × 2.5 × 0.8 m.

Is Bertrams permitted to weld load-bearing steel components?

Yes. We are certified to EN 1090-2:2018 in execution class EXC2 and meet the welding quality requirements of DIN EN ISO 3834-2. Both certificates are available for download.

When does robotic welding pay off?

For recurring assemblies with consistent geometry — the reproducible seam quality and short cycle times pay off from medium series onwards. Whether your assembly is suitable is something we clarify at the enquiry stage.
