Embodiment 1

[0035] Attached below figure 1 The argon charging device disclosed in this embodiment is further described;

[0036] Refer to attached figure 1 As shown, the argon charging device for small-caliber pipeline dense-mesh welding includes a pipe fitting 1, which is a hollow pipe.

[0037] One end of the pipe fitting 1 is provided with a flat member, and the pipe fitting 1 communicates with the flat member. The flat member includes two oppositely arranged plates 2. , the connection between the two plates and the pipe is a closed structure.

[0038] The two boards 2 are provided with through holes, and the through holes of the two boards 2 are arranged oppositely, and the through holes 2 of the two boards are all provided with a dense mesh 3 . The opening direction of the through hole is perpendicular to the axial direction of the pipe fitting 1 . The diameter of the through hole is slightly smaller than the width of the plate 2 .

[0039] In this embodiment, the pipe part 1 an...

Abstract

The invention discloses a small-caliber pipeline dense mesh welding argon filling device and method. The device comprises a pipe, wherein a flat component is arranged at one end of the pipe, the flatcomponent comprises two oppositely arranged plate pieces, the two plate pieces are connected into a whole, the two plate pieces are provided with through holes, the through holes of the two plate pieces are oppositely arranged, and dense meshes are arranged at the through holes. According to the device, the flat component is arranged, the dense meshes are arranged at the through holes of the flatcomponent, argon filling is conducted from a gap of a welding seam by adopting the device, gas outlet is uniform, and the welding quality of the welding seam is guaranteed.

Description

technical field [0001] The disclosure belongs to the technical field of small-diameter pipeline argon arc welding construction, and in particular relates to an argon filling device and method for small-diameter pipeline dense mesh welding. Background technique [0002] In the process of engineering construction, welding of small-diameter high-alloy pipes needs to be protected by filling the back of the weld with argon to ensure the welding quality of the weld. However, due to design reasons, some argon cannot be filled from the pipe side, and argon can only be filled from the weld gap. [0003] However, argon filling in the weld gap has the following disadvantages: [0004] a) The argon filling tool in the weld gap is used for a limited number of times, and it is easy to make the argon blow and impact the arc, resulting in quality defects; [0005] b) The argon filling tool in the weld gap is not uniform in gas output, which is prone to turbulent flow, resulting in reduced...
