AWS A5.10 Aluminum Welding Wire

Specification

Applications and Solutions

• Structural Fabrication (D1.2): Essential material for all load-bearing aluminum structures built to the AWS D1.2 code, including bridges, cranes, and building components.

• Pressure Vessel Code Compliance (ASME): Required material for components built to ASME Boiler and Pressure Vessel Code, Section IX, where precise chemistry is mandatory for WPS validity.

• Government and Defense Contracts: Primary requirement for most US government and defense-related aluminum welding projects where compliance is non-negotiable.

• International Standardization: Used as the reference standard by engineers and fabricators globally to cross-reference and approve consumables from international sources.

FAQ

• Q: Does an MTC guarantee full compliance with AWS A5.10?A: A Mill Test Certificate (MTC) provides the actual chemical and mechanical data of the produced lot. Compliance is achieved when that data falls within the tolerance limits defined by the specific AWS A5.10 alloy classification (e.g., ER5356). We guarantee our MTCs meet the limits.

• Q: Is there an equivalent European standard to AWS A5.10?A: Yes, the equivalent European standard is EN ISO 18273:2015, which classifies aluminum filler metals (e.g., AlSi5, AlMg5). While the standards use different naming conventions, the underlying technical requirements often overlap heavily.

• Q: What is the significance of the "ER" prefix in AWS A5.10?A: "ER" stands for Electrode or Rod. It indicates the material can be used both as an Electrode (MIG/GMAW) and as a Rod (TIG/GTAW), provided the manufacturing process for both forms adheres to the standard.
