What is the welding process of the flange

Required equipment and tools a set of manual electric welding equipment, a handle angle grinder, an electric air hammer, a plane ruler.
Welding preparation before checking and debugging equipment to ensure normal operation of the equipment; preparation φ4.0 J402 welding rod at 300 ℃ -350 ℃ drying one hour.
 Welding process assembly of the vertebrae and large flange according to the drawing requirements assembled together, and then evenly divided into 8 equal parts of the large flange; welding due to the flange is thicker, the bevel is larger, so the use of symmetrical segments, multi-layer welding.
Weld quality requirements of the weld strength at least up to the strength of the base material. The surface of the weld is flat and smooth, without burn-through, porosity, welding leakage, slag, biting edge, not fully welded and other defects. The residual height is less than 2mm.
