Abstract
A gas, which flows between a welding device and work pieces while the work pieces are welded together, has large influence on the welding. A sensor device includes a sensor unit and a container that includes a housing case (i.e., housing portion) and a shielding member (i.e., shielding portion). The shielding member is attached to the housing case, and shields radiation heat directed toward the lower surface of the housing case among radiation heat generated while the work pieces W are welded together. The shielding member is inclined with respect to a flow direction of a gas passing through an outlet port for detection of a second gas flow channel so that the gas discharged from the outlet port for detection is blown to the shielding member and thus flows to a side opposite to the side where the work pieces W are to be welded together.
