Automatic welding analysis system based on servo control

The utility model discloses an automatic welding analysis system based on servo control. The automatic welding analysis system based on the servo control comprises a signal processing unit, an execution unit, and a signal acquisition unit. The automatic welding analysis system based on the servo control has the advantages of being simple in structure, convenient to install and flexible to operate, and capable of being used for welding conditions of conventional constant-speed welding and automatic adjustment of wire feeding length. Meanwhile welding current and welding voltage can be sampled and analyzed to achieve automatic welding of welding rods.
