Hydraulic piston rod strain repair process

1. Welding technology is required for repair here, so the hydraulic piston rod should be preheated in an electric furnace first; in an environment with a temperature of 380 degrees, preheat for about 2 hours.

2. Take out the hydraulic piston rod after preheating and lay it flat on the welding table. Note that the damage surface of the hydraulic piston rod should be placed outwards;

3. On the control panel of the ion welding machine, set the required temperature and data, and then weld first. Note that the position of the welding gun should be kept about 8 mm from the hydraulic piston rod, so as to avoid vibration and other symptoms during welding. .

4. Take out the welded hydraulic piston rod with the object, and put it in the incubator for heat preservation. Do not hold the newly welded hydraulic piston rod by hand, which is very hot and easy to be scalded.

5. Then put the hydraulic piston rod of the incubator into the electric furnace to continue heating, the temperature is about 500 degrees, connect for 1.5 hours, and then let it cool naturally.
