移動させている。In the welding work using the conventional welding fume collector, the welding worker 14 shields the face from the welding light as shown in FIG.
Is performed on the welded part 17 of the welded work 13. Fume generated during welding is sucked by the hood 5 placed above the welded portion 17. The closer the hood 5 is to the weld 17, the more the welding fume is sucked into the hood 5 without being diffused, and the welding operator 14 can be prevented from inhaling the welding fume almost. In welding work, in order to avoid the effects of the welding torch 16 and light shielding surface 15,
The hood 5 is usually installed about 40 to 50 cm away from the welded portion 17. The cross-sectional shape of the hood 5 is formed in an elliptical shape in which the welding direction is a short circle, the range in which the welding fumes are effectively sucked is narrow, and the hood 5 is moved as the welded portion 17 moves.
