[0002] A hydraulic cylinder is a device that uses liquid pressure to generate mechanical movement. It consists of a sealed metal cylinder, a piston, and a rod connected to the piston. When liquid enters through the valve in the hydraulic cylinder, the liquid pressure will push the piston and rod to produce linear movement, thereby achieving the work task. A welding cylinder machine is a mechanical equipment specially used for welding. It usually consists of a welding power supply, a welding gun, a control system, etc., and can be used for various welding processes, such as arc welding, gas shielded welding, laser welding, etc. The hydraulic cylinder is subjected to a large amount of liquid pressure when working, and needs to have sufficient strength and sealing to prevent leakage and damage.
