This paper deals with the welding chamber applied to gas-shielded arc welding under the environment of strong wind. Basically, gas-shielded arc welding method itself is established technology but it is assured the welding quality only in calm environment. Generally, it is necessary to keep the wind velocity at 1.5m/s or less. The fluid chamber reported in this paper can protect against the wind velocity at 7m/s by coaxial jet what is called air curtain. This original coaxial jet generates a laminar swirl flow formed by plural "Partitions" arranged inside of the slit nozzle and assures the welding atmosphere in calm.
