Technical requirements for welding materials under the AWS A5.14 standard
This technical regulation establishes industry standards for the classification of welding consumables — bare electrodes, strip electrodes, and welding wire made from nickel and nickel alloys. The document covers alloys in which the mass fraction of nickel exceeds that of any other alloying element.
Classification system for filler materials
Filler materials complying with AWS A5.14 and AWS A5.14M specifications undergo a unified classification adapted for both the American customary system and the international SI system. The key criterion for classification is the chemical composition of the metal, detailed in industry specifications.
EV Group China engineers emphasize: each specific type of welding material is strictly assigned to its own classification group. The possibility of duplicating one grade across different groups is excluded, which ensures the predictability of the physical and mechanical properties of the weld.
Technological application capabilities
Products supplied by EV Group China in accordance with this standard are optimized for critical welding processes, including:
- Plasma Arc Welding (PAW);
- Gas Metal Arc Welding (GMAW);
- Gas Tungsten Arc Welding (GTAW);
- Submerged Arc Welding (SAW).
The materials are also compatible with other welding methods that meet the weldability requirements of the specific nickel alloy. To select the optimal wire grade for your production tasks, EV Group China specialists recommend focusing on chemical compatibility with the base metal of the structure.
