Embodiment Construction

[0049] Below in conjunction with accompanying drawing and embodiment the present invention will be described in further detail:

[0050] Such as figure 1 As shown, the present invention discloses a dust collection device for testing the amount of dust generated by automatic arc welding, which includes a dust collection box composed of a substantially closed box body 8, the shape of the box body 8 is not strictly limited, It can be a combination of a cuboid and a trapezoid as shown in the drawings, or a combination of a cylinder and a cone, and so on. The top of the box 8 is provided with a filter membrane 7 , the bottom of the box 8 is set on the base 14 , the box 8 is made of a material with a relative magnetic permeability less than 2, and the thickness of the box 8 is about 0.5 mm to 2 mm. The volume of the dust collection box casing 8 can not be too small, so that it is a principle to be easy to operate.

[0051] The filter membrane 7 is arranged on the top of the dust c...

Abstract

The invention discloses an electric arc automatic-welding welding fume collecting device and a method for testing welding fume amount. The collecting device comprises a fume collecting box, wherein the fume collecting box is provided with a box door, the top of the fume collecting box is provided with a filtering film, and a left shaft and a right shaft the inner ends of which are provided with top cones symmetrically penetrate through the wall of the box; the outer end of the left shaft is connected with a motor, and a device which is connected with and used for clamping a welding gun through an adjustable transverse guide column and a vertical guide column is arranged in the fume collecting box. The method for testing welding fume amount comprises the following steps: generating and precipitating welding fume by the device; then collecting precipitated fume, microsplash, welding slag, and the like with velvet paper and absorbent cotton; further separating the fume, the microsplash and the slag with microsize; and obtaining the fume amount in unit time by calculation. The invention improves the stability in the process of electric arc welding by automatic welding, reduces the influence of human factors, collects fume in the collecting box after natural precipitation and can realize more complete separation of the welding fume, the microsplash and the smelting slag.

Description

technical field [0001] The invention relates to a method and a device for researching welding manufacturability, in particular to a method and a device for arc automatic welding welding manufacturability research. Background technique [0002] Arc welding is a welding method widely used in modern industrial production, and most of the gas shielded welding is applied by automatic welding or semi-automatic welding process. In recent years, the application of automatic welding process has become more and more widespread. At the same time, the application proportion of non-automatic welding process represented by electrode arc welding has been greatly reduced, so technicians pay more attention to the research of automatic welding process. [0003] Welding fume will be produced in the arc welding process of metal materials, and the nature of welding fume is an important technical index in the research of welding processability. Studying the welding fume generated under different...
