Necessary equipment and tools for manual welding equipment, a handle type corner mill, an electric pneumatic hammer, a flat ruler. Prepare to check and debug the equipment before welding to ensure the normal operation of the equipment; prepare 4.0J402 electrode to dry at 300 350 C for an hour. The assembly of the welding process assembles the vertebral body and the large flange according to the drawing requirements, and then divides the large stainless steel flange into eight equal parts on average. Because the alloy steel flange is thicker, the groove is larger, so the segmental symmetrical, multi-layer welding is adopted. The weld quality requires at least the strength of the weld metal. The surface of the weld is smooth and smooth, and has no defects such as burn through, porosity, welding leakage, slag inclusion, undercut and incomplete welding. The remaining height is less than 2mm.
