SIST EN 287-6:2018

• Abstract:

  This document specifies main requirements, limits, inspection conditions and acceptance requirements as well as related inspection documents of welders for welded cast iron test pieces and workpieces.; It provides a set of technical rules for a systematic qualification test of a welder‘s skills, and enables such qualifications to be uniformly accepted independently of the type of product, location and examiner or examining body.; This document specifies the testing of a welder’s skill unless a higher level skill test is required.; The acceptance of a welder’s skill according to this document implies a practical experience and knowledge regarding the welding process, materials and safety requirements (see Annex C).; This document is to be used when requirements on part of a customer, testing or monitoring body or other organization are postulated.; This document defines the qualification test of welders for the fusion welding of cast irons. The welding processes referred to in this standard include those fusion welding processes which are designated as manual or partly mechanized welding. It does not cover fully mechanized and automated welding processes (see EN ISO 14732). Cast iron materials which are covered by this document are mentioned in 5.4.; The inspection document and certification are made out under the responsibility of the testing body.

Overview

EN 287-6:2018 - Qualification test of welders - Fusion welding - Part 6: Cast irons (CEN) defines the requirements for practical qualification tests of welders who perform fusion welding on cast iron materials. The standard specifies test piece designs, essential variables, inspection and acceptance criteria, certification rules and the responsibilities of testing bodies. It covers manual and partly mechanized welding processes for cast irons and is intended to ensure uniform, transferable welding certification across products, locations and examiners.

Key Topics

• Scope and purpose
  • Systematic qualification of a welder’s practical skill for fusion welding of cast irons.
  • Applies unless a higher-level skill test is required; implies job knowledge and practical experience (see Annex C).
• Covered welding processes
  • Manual or partly mechanized processes (EN ISO 4063), e.g. 111 (MMA), 131/135 (MIG/MAG), 141/143 (TIG), 15 (plasma), 311 (oxyacetylene), and tubular/metal-cored variations.
  • Excludes fully mechanized/automated welding (see EN ISO 14732).
• Essential variables and range of qualification
  • Defines variables such as welding process, position, joint type, material group and consumable type.
  • Qualification gives range of acceptance for easier joints when the welder has appropriate training/practice.
• Cast iron material groups
  • Material grouping in accordance with CEN ISO/TR 15608 (groups 71–76: grey, spheroidal, malleable, austempered ductile, austenitic, other).
• Weld metal classifications
  • Homogeneous (hw), semi-homogeneous (sw) and non-homogeneous (nw) weld metals; selection of suitable consumables per EN ISO 1071.
• Testing, inspection and certification
  • Test-piece geometries, welding conditions and acceptance criteria are specified; includes visual and NDT/destructive examination references (EN ISO 17637, EN ISO 3452-1, EN ISO 17639, EN ISO 9017).
  • Certificates issued by the testing body; rules on validity, re-test and prolongation are included.

Applications

• Used by: testing/inspection bodies, certification organizations, foundries, maintenance and repair workshops, contractors and employers who require recognized welder qualification for cast iron welding.
• Practical uses: qualifying welders for repair of cast components, production welding where cast iron is joined, demonstrating compliance to customers or regulators, and harmonizing acceptance across European markets.
