Shipbuilding & Marine Market Analysis

Inert Gas Shielded Welding Machine Market to Reach USD 18B by 2033 at 5.3% CAGR

Shipbuilding demand is concentrated in South Korea (KSOE, HHI), Japan (Mitsubishi Shipbuilding), and China (CSSC), with a resurgent U.S. segment driven by U.S. Navy destroyer and submarine programs under the FY2025 National Defense Authorization Act. Thick-plate MIG/MAG with flux-cored wire dominates panel-line fabrication; orbital TIG handles shaft-seal and pipe-system welding. South Korea's domestic welding automation intensity reached approximately 68 welding robots per 10,000 manufacturing workers in the shipbuilding sector as of 2024 (Claritas model).
