This document specifies the procedure to be used for deposition of a weld metal pad for chemical analysis. This document applies to deposition of a weld metal pad by use of covered electrodes, wire electrodes for gas shielded metal arc welding, tubular cored electrodes for gas shielded metal arc welding and for non-gas shielded metal arc welding, solid rods and tubular cored rods for gas tungsten arc welding, and wire-flux and strip-flux combinations for submerged arc welding or electroslag welding and cladding. This document is applicable to welding consumables for non-alloy and fine grain steels, high strength steels, creep-resisting steels, stainless and heat-resisting steels, nickel and nickel alloys, and copper and copper alloys.
Abstract
Overview
EN ISO 6847:2020 specifies the standardized procedure for depositing a weld metal pad intended for chemical analysis. It applies to a wide range of welding consumables and processes - covered electrodes, gas-shielded wire electrodes, tubular cored electrodes (with or without gas shielding), solid and cored rods for GTAW, and wire‑flux or strip‑flux combinations used in submerged arc and electroslag welding and cladding. The document replaces the 2013 edition and adds provisions for strip‑flux combinations used in cladding.
This standard ensures consistent pad preparation to support accurate chemical analysis, material qualification and quality control of welding consumables for carbon and low‑alloy steels, high‑strength and creep‑resisting steels, stainless and heat‑resisting steels, nickel and copper alloys.
Key Topics
- Scope and applicability: Defines consumable types and metallurgical groups covered (non‑alloy/fine grain steels, high‑strength, creep‑resisting, stainless, heat‑resisting, nickel and copper alloys).
- Base metal requirements: Base metal shall be compositionally similar to the deposited metal or a weldable carbon‑manganese steel with carbon
