Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a welding device for machining mechanical equipment. Background Art

[0002] Welding is a process and connection method that uses heating, pressurization, or both, with or without welding materials, to cause atomic diffusion between two workpieces to form a metallurgical bond. The welding process is related to factors such as welding methods. The operation needs to be determined according to the material, brand, chemical composition, weldment structure type, and welding performance requirements of the workpiece to be welded. First, the welding method must be determined, such as manual arc welding, submerged arc welding, tungsten inert gas welding, metal arc gas shielded welding, etc. There are many types of welding methods, which can only be selected according to specific circumstances.

[0003] Firstly, when welding cylindrical workpieces with the prior art, it is not convenient to quickly unload workpieces such as pipes. The existing structure for supporting the pipes requires the operator to move the pipes onto the supporting structure. After welding is completed, the pipes need to be moved down the supporting structure again, which makes loading and unloading of pipes inconvenient.

[0004] At the same time, when the existing technology is used to weld mechanical equipment, it is impossible to use one device to weld block and tubular structures. The existing welding equipment can only weld workpieces of one shape, resulting in the need for multiple devices to be used in coordination when processing parts of mechanical equipment in the existing technology, which has great limitations.

[0005] Secondly, in the prior art, when welding mechanical equipment, it is not convenient to make various adjustments to the workpiece. When welding the workpiece, it is necessary to adjust the angle and position of the workpiece before the welding of the workpiece can be completed. However, the prior art is not convenient to make various adjustments to the angle of the workpiece, resulting in the need to adjust the position and angle of the workpiece multiple times during welding, which reduces work efficiency. Summary of the invention
