Additive Welding Process

1. Hot-Wire TIG Cladding Process (Rotary Table Type)

The hot-wire TIG cladding process is an efficient overlay welding technique based on traditional tungsten inert gas (TIG) welding. It involves preheating the welding wire before feeding it into the molten pool, significantly enhancing deposition efficiency, reducing base metal dilution, and lowering heat input to minimize welding distortion. This process has been successfully applied in petrochemical, marine engineering, power construction, nuclear power, and aerospace industries.
