By coordinating the first synchronous electric slide rail 3 and the synchronous motor 13 to adjust the welding head position, all-around welding can be performed on the top, sides, and bottom of the welding area. After one side is welded, the welding head 11 is moved away from the welding point. The welding head 11 is adjusted by rotating the welding seat 8 with the motor 7. Welding can then be performed on the other side of the frame. The grinding motor 18 rotates the wheel 16. The top wheel 16 rotates, which drives the grinding belt 17 to rotate, so that the grinding belt 17 is in a rotating state. The fit between the grinding belt 17 and the frame surface is changed by moving the support seat 6 with the processing electric slide rail 5. After one side is polished, the position of the support seat 6 is adjusted by moving the first synchronous electric slide rail 3 and the processing electric slide rail 5. The grinding direction of the grinding belt 17 is then adjusted by rotating the welding seat 8 with the motor 7 to polish the inner side of the frame.
