The welding rod is composed of two parts of coating and welding core. The welding rod melts and adds to the weld as the filling metal, and becomes the main component of the weld metal. Such a substance is called welding rod. In order to ensure the quality of the welding rod, the welding core also needs to be polished and polished.

[0003] Under the prior art, a common way is to fix the welding rod on a special clamp or device, then make it rotate, and use polishing tools such as sandpaper, grinding wheel, etc. to polish the rotating welding rod core.
