The utility model discloses a friction welding groove structure for supporting wheel bodies of an excavator and the excavator. A groove with the radius in a range of 1-3 mm is formed in a position 6-10 mm away from one end surface of a first pressure welding part of a left wheel body, a groove with the radius in a range of 1-3 mm is formed in a position 6-10 mm away from one end surface of a second pressure welding part of a right wheel body, and extrusion bulges, produced by pressure welding, of the left wheel body and the right wheel body and the two grooves form closed structures respectively. The scheme is simple and convenient, one groove is designed in the inner side of the pressure welding part of each wheel body, high efficiency and good economy characteristics of an original scheme are kept, and above all, gaps formed between the extrusion bulges of the pressure welding parts and parent metal are effectively and completely eradicated, so that impurities such as scrap iron and the like cannot be block
