[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a welding device for irregular parts of a pressure vessel with an adjustable angle welding head, including a base 1 and a welding table 2. The welding table 2 is fixedly set at the center of the base 1. The welding table 2 includes a placement platform 3 and adjustment plates 4 set on both sides of the placement platform 3. An arc plate 5 is fixedly connected to the bottom of the adjustment plate 4. A drive cylinder 6 is connected to the rear side of the arc plate 5. An extension plate 7 is also fixedly connected to one side of the adjustment plate 4. A welding head 8 is set on one side of the extension plate 7. A welding head 8 is also fixedly set at the bottom of the placement platform 3. A fixing column 9 is also set on the base 1. A top plate 10 is fixedly connected to the fixing column 9. A welding head 8 is also fixedly set on the top plate 10. A through hole 11 is opened on the base 1, and the arc plate 5 passes through the through hole 11.

[0023] Specifically, the adjusting plate 4 is connected to the placement platform 3 via a rotating shaft 12. The rotating shaft 12 is fixedly installed on both sides of the placement platform 3. Through the above arrangement, the adjusting plate 4 can rotate around the rotating shaft 12 to adjust the angle of the welding head 8, so as to adapt to the welding requirements of irregular parts of pressure vessels with different shapes and angles.

[0024] Specifically, a baffle 13 for limiting the position is also provided on one side of the placement platform 3. Through the above setting, the irregular part of the pressure vessel can be effectively limited during the welding process to prevent it from moving or deflecting, thus ensuring the accuracy and stability of the welding. The height and position of the baffle 13 can be adjusted according to actual needs to adapt to irregular parts of pressure vessels of different sizes and shapes.

[0025] Specifically, the base 1 is also equipped with a drive motor 14 for driving the welding head 8, and the drive motor 14 and the welding head 8 are electrically connected.

[0026] Specifically, the length and width of the through hole 11 are both greater than the length and width of the arc plate 5. With the above arrangement, the arc plate 5 can pass smoothly through the through hole 11, rotate and adjust its angle without being stuck or restricted by the through hole 11, thus ensuring the flexibility and adjustability of the arc plate 5.

[0027] Specifically, welding head 8 uses the YT-50CS4HAE model welding head 8.

[0028] Specifically, the base 1 is also equipped with support feet 15 at its bottom. Furthermore, the support feet 15 include adjustable height anchor bolts 16 and shock-absorbing rubber pads 17. Through the above-mentioned configuration, the entire welding device can be placed more stably on the ground. At the same time, the adjustable height anchor bolts 16 can be adjusted according to the unevenness of the ground to ensure the levelness of the welding device, while the shock-absorbing rubber pads 17 can effectively absorb the vibration generated during the welding process, further improving the stability and accuracy of the welding.

[0029] A specific application example of this embodiment is as follows:

[0030] In use, the irregularly shaped part of the pressure vessel to be welded is first placed on the placement platform 3, and the height and position of the baffle 13 are adjusted to effectively limit the irregular part of the pressure vessel. Then, the drive cylinder 6 pushes the arc-shaped plate 5, causing the adjusting plate 4 to rotate around the rotating shaft 12, thereby adjusting the angle of the welding head 8 to adapt to the shape and angle of the irregular part of the pressure vessel. Next, the drive motor 14 is started, and the welding head 8 begins to work, welding the irregular part of the pressure vessel. During the welding process, the parameters of the welding head 8, such as welding current and welding speed, can be adjusted as needed to obtain the best welding effect. At the same time, since the bottom of the base 1 is provided with support feet 15, and the support feet 15 include adjustable height anchor bolts 16 and shock-absorbing rubber pads 17, the stability and accuracy of the entire welding device during the welding process can be ensured. Through the welding device of this embodiment, efficient and accurate welding of irregularly shaped parts of pressure vessels can be achieved, improving welding quality and production efficiency.
