Overview

oSIST prEN 18354:2026 specifies the procedure for testing welding consumables by preparing and evaluating weld metal specimens. The primary focus is determining the hardness of surfacing produced by fusion welding on steel. Developed by SIST and put forth for European standardization, this standard ensures that testing is conducted with consistency and reliability across different suppliers and manufacturers. By standardizing the preparation, welding, and testing procedures, this document supports quality assurance in welding consumables intended for surfacing applications.

Keywords: welding consumables, hardness testing, surfacing, steel, fusion welding, test piece preparation, European standard, SIST

Key Topics

• Preparation of Test Pieces
  The standard outlines the materials, dimensions, and preparation methods for test pieces. Steel grade S235JR is specified as the base plate, with precise requirements for size and surface quality to ensure uniformity in testing.

• Welding Procedure
  Only consumables of the same batch and nominal diameter are used per test piece. Procedures such as cleaning, electrode handling, welding position (PA position per EN ISO 6947), and temperature control (per EN ISO 13916) are standardized.

• Test Piece Types
  Two main types of test pieces are described, varying by welding process and consumable. Each type includes specifications for dimensions, welding runs, and sequencing to simulate real surfacing applications.

• Machining and Test Surface Preparation
  The test piece is machined to achieve a flat surface, with the top weld layer ground to expose sufficient area for testing. Careful preparation is essential to produce valid and reproducible results.

• Hardness Testing
  Hardness is determined through standardized indentation tests, such as Brinell, Vickers, or Rockwell, as referenced in related standards. The distribution of measuring points and avoidance of surface imperfections are crucial for accurate results.

• Test Reporting
  Detailed reporting requirements ensure traceability and clarity. Reports must include information on consumables, welding parameters, materials, preparation steps, and all relevant test results.

Applications

oSIST prEN 18354:2026 is directly relevant to industries where durable and hard surfacing is critical, such as:

• Manufacturing and repair of wear-resistant components:
  Used in mining, construction, and heavy machinery, where surface hardness is essential for performance and longevity.

• Welding consumable quality control:
  Helps manufacturers and suppliers verify the properties of welding consumables and meet regulatory or customer requirements.

• Laboratory and research settings:
  Standardized testing procedures facilitate comparative studies, product development, and process optimization for surfacing applications.

• Certification and compliance:
  Supports organizations in demonstrating conformity to European and international welding standards, fostering trust in product quality.

Related Standards

For comprehensive compliance and further technical guidance, refer to these associated standards:

• EN 10025-2: Hot rolled products of structural steels - Technical delivery conditions for non-alloy structural steels.
• EN ISO 6947: Welding positions for welding and allied processes.
• EN ISO 13916: Measurement of preheating and interpass temperature in welding.
• EN ISO 6506-1, 6507-1, 6508-1: Methods for Brinell, Vickers, and Rockwell hardness testing.
• EN ISO 6847: Deposition of a weld metal pad for chemical analysis.
• EN ISO 15792-1: Preparation of all-weld metal test pieces in steel, nickel, and nickel alloys.

oSIST prEN 18354:2026 provides a critical framework for consistent, reliable assessment of the hardness of surfaced steel, supporting high-quality welding practices across Europe and internationally.
