Overlay Welding Machine for Hydraulic Cylinder Inner Hole

Main Features:
Welding torch enters into the cylinder barrel and moves longitudinally along the barrel driven by high power servo motor. The cylinder rotates, welding position is horizontal.
The cylinder clamped by chuck to rotate and supported by bracket underneath.
PLC controls the whole machine operating. The welding rotating speed, welding torch traveling and welding voltage can be adjusted via the touch human-machine interface.
Welding parameters can be preset and memorized.
