To help welders better assess the suitability of their tubular filler metal to their welding application and to enhance the overall understanding of tubular wires, Hobart Brothers Co is offering a poster explaining the American Welding Society (AWS) classification system for four types of tubular wire.

With explanations of the classification system for mild steel flux-cored wire, mild steel metal-cored wire, low alloy flux-cored wire, and low alloy metal-cored wire, the poster is available free of charge by calling (937) 339-9425. A smaller version of the poster can also be downloaded from at

The AWS Classifications poster is the third in a series of free educational posters.
