The automatic MIG welding and MAG welding switching island arc welding system comprises a welding machine (1), a welding gun (2), a wire feeder (4), a gas bottle rotation switchover mechanism, a wire feeding lifting mechanism and a controller. The welding machine (1) is connected with the welding gun (2). The gas bottle rotation switchover mechanism is provided with a MIG welding gas bottle (5) and a MAG welding gas bottle (6). The wire feeding lifting machine is provided with a MIG welding wire disc (7) and a MAG welding wire disc (7). The gas bottle rotation switchover mechanism is connected with the welding machine (1). The wire feeding lifting mechanism is connected with the wire feeder (4). The controller is connected with the gas bottle rotation switchover mechanism and the wire feeding lifting mechanism. Compared with the prior art, the automatic MIG welding and MAG welding switching island arc welding system has the beneficial effects that the structure is simple, the automation degree is high, manpower and material resources can be saved, equipment resources are saved, and the work efficiency is improved.

Description

technical field [0001] The invention relates to an arc welding island system, in particular to an arc welding island system for automatic switching between MIG welding and MAG welding. Background technique [0002] Metal inert gas shielded welding (MIG welding) uses a melting electrode, an additional gas is used as an arc medium, and an arc welding method that protects metal droplets, welding pools and high-temperature metals in the welding zone is called MIG arc welding. The inert gas (Ar or He) shielded arc welding method with solid wire is called molten inert gas shielded welding, or MIG welding for short. Metal active gas shielded arc welding (MAG welding) is a kind of mixed gas shielded welding formed by adding a small amount of oxidizing gas (oxygen, carbon dioxide or a mixture thereof) to argon gas. The mixed gas of 80% Ar+20% carbon dioxide is commonly used in our country. Since the proportion of argon in the mixed gas is relatively large, it is often called argon-r...

AI Technical Summary

Problems solved by technology

[0003] Since the welding wire and shielding gas required for MIG welding and MAG welding are different, independent equipment and sites are generally used in the welding of automobile body-in-white, which will inevitably cause waste of resources. At the same time, several types of welding cannot be completed at one time. In the process, it is necessary to transport the welded parts to a specific site for corresponding welding, so a lot of manpower and material resources are required, the cost is increased, and the work efficiency is low.
