An all-welded frame of an electric wheel dump truck comprises a first longitudinal beam and a second longitudinal beam. A front bumper, a front traction crossbeam, a gantry beam, a rear traction crossbeam and a rear crossbeam are arranged between the first longitudinal beam and the second longitudinal beam sequentially from front to back, and carriage hinge pedestals are arranged on the rear crossbeam; all the front bumper, the front traction crossbeam, the gantry beam, the rear traction crossbeam and the rear crossbeam are welded to the first longitudinal beam and the second longitudinal beam, and welding joints are full penetration welding joints; both the first longitudinal beam and the second longitudinal beam are fish-bellied variable-section box beams, welding pads are arranged on the reverse sides of box-type closed welding joints of the fish-bellied variable-section box beams, and the welding joints of the fish-bellied variable-section box beams are full penetration welding joints; the gantry beam is a large arc-ring shaped box beam, welding pads are arranged on reverse sides of box-type closed welding joints of the large arc-ring shaped box beam, and the welding joints of the large arc-ring shaped box beam are full penetration welding joints. The all-welded frame is high in rigidity and strength, light in structure and low in cost.
