The Importance of Application of EN ISO 3834 and EN 1090 in Production of Steel Structures

Abstract

Abstract Fractures of welded structures in operational conditions most often occur in the welded joint or its immediate vicinity. Due to this, special attention is paid to ensuring the quality of the welded joint. The application of the EN ISO 3834 and EN 1090 standards in the manufacture of steel structures aims to ensure the highest possible quality of welded joints, and thus the quality of the structures as a whole. Weld quality is achieved by welding, whereas weld quality control provides a check of product reliability. Increasing requirements in terms of reliability, better use of materials, lower weight and cost of constructions, but also high use of load-bearing structural elements, and thus welded joints, leave less room for errors in welded joints, which is why constant control and monitoring of documented procedures is required.
