Description

Technical Field

[0001] The invention relates to the technical field of metal welding, in particular to automatic welding equipment for metal processing. Background Art

[0002] Metal pipe welding is a process for connecting two or more metal pipes. It is widely used in construction, machinery manufacturing, petrochemical and other industries. The choice of welding method depends on factors such as the type of pipe, the diameter of the pipe, the required strength and cost. Common welding methods include gas welding, arc welding, resistance welding, laser welding, tungsten inert gas welding and plasma arc welding. Most existing welding equipment does not limit the welding slag generated by welding, resulting in a large range of welding slag falling.

[0003] After searching, the Chinese patent with publication number CN218575224U discloses a metal tube welding tool and a metal tube welding device, including: a base, two fixing parts, two driven gears, two driving gears, a rotating shaft and a welding machine. When the above-mentioned metal tube welding tool and metal tube welding device are actually used, the two chucks are rotatably connected with the fixing parts one by one. When the rotating shaft is rotated, the rotating shaft drives the two driving gears to rotate synchronously, the two driving gears drive the corresponding driven gears to rotate synchronously, and the two driven gears drive the corresponding chucks to rotate synchronously. When the two chucks rotate synchronously, they drive the two corresponding clamped metal tubes to rotate synchronously and coaxially. In this way, the two metal tubes to be welded have higher synchronization when rotating, and then the uniformity of the weld thickness can be better when the two metal tubes are welded by the welding machine, so as to improve the welding quality.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] During the welding process of current welding equipment, the welding slag generated during welding has a large falling range due to the lack of restrictions. During welding, the welding slag is also easily attached to the surface of the welding gun, which leads to a high subsequent cleaning pressure. On the other hand, inert gas is currently introduced during the welding process to reduce the degree of welding oxidation, but the control switch system of the inert gas is independent of the welding system. Therefore, in actual operation, the inert gas is not easy to be switched on and off synchronously with the welding system. For example, the inert gas is generally introduced first, and then the welding operation is performed, which will result in a certain waste of inert gas, so there are limitations.
