Flux Cored Welding Wire Market Dynamics

Drivers

Rising demand for high-deposition, low-defect welding in large infrastructure and shipbuilding

The global boom in infrastructure investment, including megaprojects, ports, and naval defense, has increased the use of flux cored wires. In 2023, over 600 infrastructure projects across 42 countries incorporated flux-cored wire welding. Shipbuilding activities in Asia-Pacific led consumption, with more than 178 naval ships and 650 merchant vessels incorporating hull and deck welding using flux-cored wires. These wires provide higher productivity rates of up to 10 kg/hour and minimize spatter and post-weld cleanup. Structural steel fabricators used more than 740,000 metric tons of wire in 2023 due to the need for full-penetration welds and faster assembly times.

Restraints

Demand for alternative welding methods in clean environments

Despite the advantages, flux-cored wire is not universally preferred.
