Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a dressing device and all-position submerged arc welding equipment. Background Art

[0002] In pipeline welding, especially in all-position submerged arc welding (ASAW), flux management and the design of the flux applicator are crucial to welding quality and efficiency. In traditional welding methods, the welding gun moves along the fixed pipeline. Without a flux applicator, flux can easily fall during welding, exposing the molten pool to air. This increases the risk of porosity and oxidation, seriously impacting weld quality.

[0003] To address this issue, the initial solution was to introduce a dressing device, whose purpose was to maintain continuous coverage of flux during welding to protect the molten pool from air. However, early dressing device designs, particularly those with full-circular shapes, had significant drawbacks. This design significantly increased the travel resistance of the dressing device and welding gun as the driver moved them along the pipeline. This increased resistance not only reduced welding speed and efficiency but also could cause the welding gun to move unsteadily, increasing instability during the welding process and affecting the uniformity and quality of the weld.

[0033] In the technical solution of the present invention, the arc-shaped opening 11 of the material bag 1 is fitted on the product to be welded 200, the welding gun 21 is adjusted to align with the weld seam, the flux is filled into the material cavity through the feed port 12, the rotary drive member is started, and the welding gun 21 and the material bag 1 connected to the welding gun 21 are driven to rotate along the product to be welded 200, the welding gun 21 contacts the flux and strikes an arc to form a weld at the connection of the product to be welded 200, by ensuring that the flux effectively covers the weld seam, reducing pores and oxidation, and improving the welding quality, the rotary drive member drives the welding gun 21 to rotate along the pipeline, realizing automatic welding and improving efficiency; in this dressing device 100, the design of the arc-shaped opening 11 is easier to fit Products 200 to be welded of different diameters and shapes make the submerged arc welding equipment more adaptable and flexible; the design of the arc-shaped opening 11 also reduces the contact area between the bag material piece 1 and the product to be welded 200, thereby reducing the friction and driving resistance of the welding gun 21 and the bag material piece 1 when moving along the product to be welded 200. Due to the reduction in driving resistance, the welding gun 21 moves more smoothly, reducing welding defects caused by shaking or unstable movement, and improving the stability of the welding process, the uniformity and quality of the weld; and a small amount of water glass solution can be added to the flux to fill the void area inside the flux to ensure sufficient reaction between the flux and the molten pool.

[0034] To facilitate the fixing of the welding gun 21, please refer to Figure 1In one embodiment of the present invention, the welding assembly 2 includes a fixing part 3, and an insertion opening 13 is provided on a side wall of the bag material part 1 facing the welding gun 21. The fixing part 3 includes a first fastener and two fixed half rings 31, one of the fixed half rings 31 is connected to the side wall of the bag material part 1, and the two fixed half rings 31 surround the insertion opening 13.

The bag material part 1 is a component in the device for carrying and storing flux, and a discharge port 14 is specially opened on one side wall thereof for discharging excess welding slag during the welding process and discharging free welding slag generated during the welding process to maintain the stability of the flux inside the bag material part 1 and the welding quality; during the welding process, the flux below the bag material part 1 participates in the submerged arc welding reaction to generate welds and welding slag, resulting in the consumption of flux. The flux in the upper layer of the bag material part 1 dynamically replenishes the flux in the lower layer to ensure the stability of the flux amount below during the welding process, and some free submerged arc welding slag is discharged through the discharge port 14 to avoid these welding slags from having adverse effects on subsequent welding processes, such as contaminating welds or affecting the formation of welds; by dynamically managing the flux and discharging the welding slag in time, the stability of the welding process and the quality of the weld are improved. The design of the discharge port 14 reduces the accumulation of welding slag inside the bag material part 1, reduces the interference of welding slag on the welding process, and the dynamic replenishment of flux ensures the continuity and uniformity of the flux during welding, thereby improving the utilization rate of the flux.

[0036] To check the quality of the weld, refer to Figure 4In one embodiment of the present invention, the pocket material piece 1 includes a fixing plate 15, and a weld inspection port is opened on one side wall of the pocket material piece 1. The fixing plate 15 is detachably connected to one side wall of the pocket material piece 1 and can cover or open the weld inspection port.

The fixing plate 15 is detachably connected to one side wall of the pocket piece 1, which can be through screws or bolts. The present invention does not impose any restrictions on this. The fixing plate 15 is used to cover or open the weld inspection port. After welding is completed, the weld inspection port is opened by removing the fixing plate 15 to perform weld quality inspection, including knocking off the welding slag on the weld surface to complete the welding process. The weld inspection port covered by the fixing plate 15 can be used to conveniently inspect the weld quality to ensure welding quality. During the welding process, the fixing plate 15 protects the weld from external interference, such as dust, moisture, etc., to ensure the stability of the welding environment. The detachable connection design makes the disassembly and installation of the fixing plate 15 simple and quick, thereby improving the efficiency of the welding operation.
