Description:
L1 flux is a common, widely-used type of submerged arc welding (SAW) flux. It’s known as a neutral flux, meaning it doesn’t significantly alter the manganese (Mn) or silicon (Si) content from the wire into the weld metal, providing consistent mechanical properties. L1 flux typically produces smooth, well-shaped weld beads and is suitable for welding various carbon and carbon-manganese steels, particularly in single-pass and general multi-pass applications where good impact strength isn’t the primary concern. It’s generally classified under the F7A2/F7P2 specification (or similar, depending on the wire) when paired with a suitable wire.
