Overview
EN ISO 19288:2016 (ISO 19288:2016) sets out a classification system for welding consumables - specifically solid wire electrodes, solid wires and rods used for fusion welding of magnesium and magnesium alloys. The standard classifies these consumables by chemical composition and is applicable across common fusion processes including MIG (metal inert gas), TIG (tungsten inert gas), plasma, laser and laser‑MIG hybrid welding. EN ISO 19288:2016 is the CEN-adopted European version of the ISO document.
Key topics and requirements
- Classification basis: Consumables are classified solely by their chemical composition; the welding-process symbol is not used because identical compositions are used across multiple processes.
- Product symbol: All solid wires/rods use the symbol S.
- Chemical symbols and numeric codes: Numerical symbols indicate alloy groups (see Table 1 in the standard); optional additional chemical symbols identify characteristic alloying elements.
- Chemical analysis: Requirements for chemical testing of the product or source stock are specified. Any analytical technique may be used; in disputes, established published methods apply.
- Rounding and units: Rounding rules follow ISO 80000-1 to determine compliance; measured values must be converted to the standard’s units before rounding.
- Retest procedure: Failed tests must be repeated twice; retests must meet requirements or material is considered non‑conforming. For chemical failures, only the failed elements need retesting.
- Mechanical properties: Not specified - mechanical properties of welded joints/all‑weld metal are excluded from this classification.
- Technical delivery conditions: Delivery and procurement requirements refer to ISO 544 and ISO 14344.
Applications and users
EN ISO 19288:2016 is practical for:
- Welding consumable manufacturers who label and certify solid wires and rods for magnesium welding.
- Procurement and quality managers specifying filler materials for suppliers and purchase documents.
- Welding engineers and fabrication shops selecting compatible filler metals for magnesium and magnesium‑alloy joining.
- Testing laboratories and conformity assessors performing chemical analysis and compliance checks.
- Industries where magnesium alloys are used (automotive, aerospace, electronics, and lightweight manufacturing) will use the standard to ensure material traceability and specification alignment.
