Description

technical field [0001] The invention belongs to the technical field of welding devices, and in particular relates to a welding device with a lifting structure for large-scale steel structure engineering. Background technique [0002] Welding: also known as welding and welding, is a manufacturing process and technology for joining metal or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. Welding achieves the purpose of joining through the following three ways: Fusion welding - heating the workpiece to be joined to make it partially melt to form a molten pool, and the molten pool is cooled and solidified before joining. If necessary, fillers can be added to assist. It is suitable for various The welding process of metals and alloys does not require pressure; pressure welding - the welding process must exert pressure on the weldment, which belongs to the processing of various metal materials and some metal materials; brazing...

AI Technical Summary

Problems solved by technology

It is suitable for welding processing of various materials, and is also suitable for welding processing of different metals or heterogeneous materials. However, the existing welding devices and welding heads are generally fixed and installed, which is inconvenient to remove for replacement or maintenance, and the existing welding When the device is welding on the side, the workpiece needs to be turned 90° to weld the side, which affects the work efficiency
