Required equipment manual welding equipment, a hand-held angle grinder, an electric pneumatic Hammer, a ruler.
Pre-welding preparation
1. Check the debugging equipment, ensure the normal operation of the equipment;
2. Prepare 4.0J402 electrodes, preferably dried at 300-350 °C for one hour.
Welding Process
1, assembly the vertebral body and big flange according to the drawing requirements of assembly together, and then the average big flange into 8 equal parts.
2, welding because the Flange is thicker, the groove is bigger, therefore uses the subsection symmetry, the multi-layer welding. Weld Quality Requires Weld strength to be at least as high as that of the base metal. Weld surface smooth, no burn through, blowhole, welding leakage, slag inclusion, undercut, not full welding and other defects. The residual height is less than 2 mm.
