[0003] In existing petroleum machinery, cylindrical mechanical parts need to be welded. The existing welding method is to manually connect two welded parts and then weld them with a manual handheld welding gun. This welding method is inaccurate and easily leads to welding deviation, thereby reducing welding quality.

[0004] After searching, the existing patent: A welding platform for petroleum machinery processing (application number: CN202222655747.3) includes a rotating table, a fan, a purification box, a support plate and a hose, a rotating table is arranged above the support plate, a motor is arranged inside the support plate, a fan is arranged below the support plate, a purification box is arranged on one side of the lower end of the support plate, a plurality of activated carbon plates are arranged inside the purification box, a hose is arranged at one end of the fan, a slide groove is opened inside the edge of the support plate, a plurality of sliders are slidably installed inside the slide groove, a gas nozzle is arranged at one end of the hose, and a universal tube is sleeved on the outer wall of the hose. The utility model has the function of effectively purifying the harmful gases generated by welding. The harmful gases are extracted and transported to the inside of the purification box by the fan, and the harmful gases are purified by activated carbon, which protects the health of the workers and solves the problem that the existing welding platform does not have the function of effectively purifying the harmful gases generated by welding.

[0005] Although the above patent has the function of effectively purifying harmful gases generated by welding, the harmful gases are extracted by the fan and transported to the inside of the purification box, and the harmful gases are purified by activated carbon, which protects the health of the workers and solves the problem that the existing welding platform does not have the function of effectively purifying harmful gases generated by welding. However, when the device is in use, when users of different heights use it, the required height of use will also be different. The device cannot adaptively adjust its height. At the same time, when performing welding operations, there is no support at the welding point, and it is easy to shake during welding operations, which can easily lead to welding errors and is inconvenient for users to use. Therefore, it is necessary to invent a welding platform for petroleum machinery to solve the above problems. Utility Model Content
