AWS Class 35/45 welding wires are a go-to choice for general-purpose welding of carbon steel structures and components. You’ll find them commonly used in building frames, bridges, storage tanks, machinery parts, pipelines, and the fabrication of plates and sections. They’re perfect for both workshop fabrication and on-site erection and maintenance welding. Thanks to their excellent weldability and well-balanced mechanical properties, these wires are favored in construction, shipbuilding, infrastructure projects, and repair work where consistent strength and ease of use are essential.
