Forming weld seams: Important standards at a glance
The forming welding process is influenced by various standards in Germany and Austria. These standards cover areas such as the qualification of welders, the quality of shielding gases and temperature control. In general, there are a number of standards that define the requirements for welding:
- DIN EN ISO 9606-1: Checks welder qualifications to ensure that the necessary skills for welding work, including forming, are available.
- DIN EN 1090: Regulates the requirements for steel structures, including the preparation, execution and quality assurance of weld seams. This standard is relevant for forming when it comes to load-bearing steel structures.
- DIN EN ISO 15614-1: This standard deals with the qualification of welding processes, which also includes forming. It specifies requirements for the documentation of the forming process, which contributes to quality assurance.
- ÖNORM EN 1011-1 to 8: These Austrian standards provide guidelines for welding different materials and processes and also have an influence on forming.
- DIN EN ISO 17663: This standard specifies the quality assurance measures for thermal cutting and welding, including requirements for process monitoring.
- DIN EN ISO 14175: The requirements for shielding gases are defined here, which plays an essential role in the forming process. The selection of the right gas and its application are decisive for the quality of the weld seam.
- DIN EN ISO 13916: Temperature control is a key factor in moulding and this standard specifies the requirements for temperature measurement and monitoring.
Specific standards for moulding in detail
While the standards mentioned above are more general, there are specific regulations that deal directly with moulding and the associated processes:
DIN EN ISO 14175 (shielding gases): This standard is crucial for forming, as it specifies requirements for the composition and use of shielding gases. As a shielding gas atmosphere is created for the weld seam during forming, the choice of the right gas and its correct use are crucial to avoid oxidation and contamination.

DIN EN ISO 15614-1 (Qualification of welding procedures): The qualification of welding processes is essential for forming, and this standard regulates the testing and documentation of the process. Parameters such as gas flow, pressure and temperature are crucial for validating the suitability of the forming process and ensuring the desired welding quality.

DIN EN ISO 13916 (temperature monitoring): A stable temperature during the welding process is essential for the quality of the weld seam during forming. This standard contains specifications for precise temperature measurement and control in order to avoid deformation or cracking. Correct temperature management ensures a stable and uniform protective atmosphere.

Conclusion
There are many aspects to consider when forming, and compliance with the standards ensures that the welding process is carried out correctly and safely. While standards such as DIN EN 1090 and ÖNORM EN 1011 influence the process in general, DIN EN ISO 14175, DIN EN ISO 15614-1 and DIN EN ISO 13916 in particular are crucial to ensure the quality and precision of the forming process. A deeper understanding of these regulations helps to ensure that the forming process is successful and conforms to the standards.
