Welded Fabrication Certification

Importance of Welded Fabrication

Welded fabrication plays a critical role in many industries in terms of product durability, quality, and safety. Therefore, ensuring compliance with relevant national and international standards is of great importance.

Scope of Certification for Welded Fabrication

  • EN 1090 – Steel Constructions
  • PED – Pressure Equipment Directive
  • EN ISO 3834 – Welding Quality Requirements
  • EN 15085 – Welding Standard for Railway Applications
  • WPQR – Welding Procedure Qualification Record
  • WPS – Welding Procedure Specification
  • EN ISO 9606-1 – Welder Certification

EN 1090: Compliance in Steel and Aluminum Structures

The EN 1090 standard defines conformity assessment requirements for the production and assembly of structural steel and aluminum products. It is particularly important in the construction industry to ensure product safety and usability.

EN ISO 3834: Quality in Welded Fabrication

EN ISO 3834 specifies quality requirements at all stages of welded fabrication, including:

  • Design
  • Material selection
  • Welding methods
  • Quality control and testing processes

EN 15085: Standard for Railway Systems

EN 15085 ensures the safety of welding processes used in the production of railway vehicles and components. Its application aims to meet high safety and quality requirements in the railway industry.

WPQR (EN ISO 15614-1): Welding Procedure Qualification Record

The WPQR demonstrates that a specific welding method has been tested and meets the requirements of the standard. This process verifies the reliability and repeatability of welding procedures.

WPS: Welding Procedure Specification

The WPS defines the technical parameters and methods to be applied for a specific welding process. This document ensures the process is carried out in compliance with standards.

EN ISO 9606-1: Welder Qualification

EN ISO 9606-1 evaluates the competence of welders for a specific welding operation. Upon successfully passing the required tests, the welder’s qualification is certified.

🔹 Compliance with standards such as EN 1090, EN ISO 3834, EN 15085, and WPQR in welded fabrication processes is critical for product safety, durability, and market acceptance.
