DIN EN 1090 officially came into force on 1 January 2011. In order to obtain approval from building officials across Europe to manufacture steel constructions, companies must meet the applicable technical standards. Only companies that fulfil the requirements laid down in this standard and which have been inspected and certified by a recognised body may be commissioned to manufacture metal structures (e.g. welded steel structures). Companies that wish to manufacture welded steel structures or perform welding on existing steel structures must prove that they have suitably qualified employees and the required technical equipment. Certified companies must arrange regular inspections to ensure that they are still working in line with the standard. Among other aspects, conforming to this standard involves working in compliance with the quality requirements laid down in DIN EN ISO 3834 in the appropriate level of quality.
To obtain approval from building officials to manufacture structural components, companies must fulfil the following requirements pursuant to DIN EN 1090.
Part 1 Requirements for conformity assessment for structural components
Part 2 Technical requirements for the execution of steel structures
The requirements to be fulfilled are determined by the applicable execution class (EXC) pursuant to DIN EN 1090-2. One of four execution classes ranging from EXC 1 to EXC 4 is allocated depending on the load put on the structural component, the type of steel used, the damage category and other criteria.
AXZION-GKS has been approved for class EXC 3. The highest class, EXC 4, does not apply to lifting equipment.
Class EXC 3 applies to structural components that have the potential to cause a high degree of damage and that are predominately exposed to static or dynamic load conditions as well as to steels with a yield strength > 355 MPa.
Companies belonging to class EXC 3 must appoint a qualified welding supervisor and certified welders who hold valid welder certification in accordance with DIN EN 287-1 or DIN EN ISO 9606-1 and must follow a welding procedure supported with a valid Welding Procedure Qualification Record (WPQR).
DIN EN 1090-1 requires that companies have a certificate relating to their in-house factory production control system and a welding certificate, both of which must be obtained from a recognized body after an initial inspection. The companies are also subjected to regular inspections of their in-house factory production control systems.
Certified by DVS ZERT and TÜV Rheinland
AXZION-GKS has certifications ranging from the manufacturer’s qualification for fusion welding pursuant to DIN EN ISO 3834-2 and the DIN EN 1090-1 manufacturer certification, to an in-house factory production control system for structural components up to EXC 3 pursuant to EN 1090-2 and quality management systems certified according to DIN EN ISO 9001.
Our professional welding engineers design the constructions in a way that makes them suitable for welding and also measure the welded joints required. The welding process and results are laid down in a WPS (Welding Procedure Specification) pursuant to EN ISO 15609-1.
Welding in line with a WPS means that the process is carried out according to a certified Welding Procedure Qualification Record (WPQR). This serves as a set of instructions on how the welded joints are to be produced and which settings the welder must use on the welding equipment. It also includes instructions on how to prepare and finish the joints.
We attach immense importance to the quality of the welded joints that we produce. All welders possess valid welder certificates pursuant to DIN EN 287-1 and/or DIN EN ISO 9606-1 and undergo continuous in-house training.
Only ultra-modern welding equipment is used and this is regularly inspected and continually updated.
The only way that perfect quality can be achieved at an affordable price is through the use of new and modern manufacturing machinery. Our production lines live up to this ideal. All flame and plasma cutting machines are CNC controlled, while our numerous large boring machines and portal milling machines ensure all components are manufactured to a high quality. We work in line with the common mechanical engineering standards. Replacement parts can be reproduced and dispatched at very short notice and adjustments to the lifting equipment are generally unnecessary.
However, modern CNC-controlled machinery is only as good as its operator, which is why our specialists receive continuous in-house training. We, of course, also work hard to instruct the technicians of tomorrow. SolidCAM transfers the designed components directly to the machinery, minimising transfer errors.
CNC-controlled sawing and drilling machinery is used to cut and process beams and is capable of automatically sawing down steel sections and drilling directly into them.
By manufacturing welded components using our large CLOOS robotic welding systems with eight controlled robot axes, perfectly welded joints can be created with remarkable speed.
Components capable of working at high intensities are manufactured cost effectively in our plant in the Czech Republic, where the required welding certifications are, of course, also in place.
A highly efficient logistics system is particularly important for large welded components. As such, our tall and spacious manufacturing plants are equipped with a number of overhead and jib cranes and enable the production line to run smoothly. In the case of urgent demand, the manufacturing capacity can be markedly increased in the short term.
