Description

Technical Field

[0002] In the piping system of central air conditioning, the pipes are arranged in a complex and dense manner, and there are many cross-space settings of the pipes. Usually, welding is performed on the corresponding pipes and the positions of the corresponding pipes are fixed to ensure that they are in a stable working state.

[0003] For example, an automatic welding device for air-conditioning pipes with the announcement number CN206105280U includes a fixed plate, two relative rotating bearings are provided on the fixed plate, the rotating bearings are fixedly mounted on the fixed plate through a bearing frame, and the bearing frame is welded to the outer bearing of the rotating bearing; a gear ring is welded to the outer side of the inner bearing of the two rotating bearings, two synchronous gears are provided above the two gear rings, the synchronous gears and the gear rings are meshed with each other, and the two synchronous gears are connected by a synchronous shaft, and the synchronous shaft is fixed by a synchronous shaft bracket installed on the fixed plate, and the synchronous shaft passes through the synchronous shaft bracket and is rotatably connected to it; a welding gun is provided in the middle of the fixed plate, and the welding gun is fixed to the fixed plate through the welding gun bracket, which improves the efficiency of the air-conditioning pipe welding work and reduces the air-conditioning The installation time is short and the welding effect is good. However, the air-conditioning pipes need to be preheated before welding. Preheating can reduce the cooling rate of the welded joints, which is beneficial to the escape of diffused hydrogen in the weld metal, avoid hydrogen-induced cracks and the appearance of martensite hardened structure, improve the crack resistance of the welded joints, reduce welding stress, and reduce the temperature difference between the welding area and the overall temperature of the weldment. The device is not convenient for preheating the air-conditioning copper pipes, which may cause welding deformation and reduce the subsequent welding quality. In addition, smoke and dust will be generated during the welding of copper pipes. These smoke and dust are mainly composed of copper oxides, tiny particles and other harmful substances. Long-term inhalation of these substances may cause occupational diseases such as pneumoconiosis and respiratory diseases. Therefore, the smoke and dust generated by welding also need to be collected and treated in time.
