AWS A5.17 Classification

AWS A5.17 is an American Welding Society (AWS) specification for classifying carbon steel electrodes and fluxes for submerged arc welding (SAW). Here's a breakdown of the key information:

• Process Focus: Submerged arc welding (SAW) is a high-productivity welding process that utilizes a continuously fed consumable electrode and submerged flux to create a weld. AWS A5.17 deals with the classification of both the electrodes and the fluxes used in this process for joining carbon steels.

• Classification System: The AWS A5.17 specification incorporates two separate classification systems:

  • Electrode Classification: Electrodes are classified based on their chemical composition using a system similar to solid welding electrodes (e.g., AWS A5.18). The classification code typically follows a format like EMXXX (where X can be a number or letter). Here, "E" signifies an electrode and the following letters and numbers indicate the specific composition.
  • Flux Classification: Fluxes are classified based on the mechanical properties of the weld metal they produce in combination with a specific electrode classified under AWS A5.17. The classification code typically follows a format like FXXX (where X can be a number or letter).

• Code Selection: When using AWS A5.17, you'll need to select both an electrode and a flux classification that are compatible with each other and suitable for the specific application and base metal being welded.

• Applications: Carbon steel electrodes and fluxes classified under AWS A5.17 are used in various industries for high-deposition rate welding of carbon steels. Here are some common applications:

  • Shipbuilding: For fabricating large sections of ships.
  • Heavy equipment manufacturing: Building frames, buckets, and other components for construction equipment.
  • Pressure vessel fabrication: Welding thick-walled vessels used in various industries.
  • Structural steel fabrication: Building bridges, buildings, and other structures.

• Benefits of Using AWS A5.17 Classified Consumables:

  • Standardized Performance: The classification system ensures consistent properties of electrodes and fluxes, leading to predictable weld quality.
  • Selection Guidance: The system aids in selecting compatible electrodes and fluxes for specific applications and base metals.
