                                            Hydraulic Cylinder Single Torch Circular Seam Welding Machine

1.Welding Requirement

Mainly used in welding hydraulic cylinder circular seam automatically. To guarantee the welding specification is even and uniform, welding seam has good and uniform appearance. It is convenient and reliable to use and the welding quality meets to the requirement.

2. Main Feature

Workpiece is positioned by special fixture and pressed by pneumatic thimble. Rotating synchronously. Loading and unloading bracket are mounted under the workpiece.

Using Panasonic YG-500KR2 welding power source which has good performance of arc igniting, arc stabilizing and arc ending, to ensure that the welding seam is even and uniform.

The welding mode and welding specification can be preset, saved and recalled.  It is convenient to modify the parameter and switch the status through the man-machine interface touch screen. Welding length, arc igniting &ending time, welding current, welding voltage, welding speed,  oscillating frequency, oscillating scope, oscillating time, torch lifting time, lifting distance, lifting times can be all input through the interface.

Welding current and welding voltage are controlled by D/A (digital analog). They can be preset and recalled in layer. To realize multi-layer continuous welding when the arc does not stop.


Welding torch oscillating and lifting mechanism is used to weld wide and multi-layer seams of hydraulic cylinder.

3.Equipment Composition

It consists of machine body, rotary axis power mechanism, welding torch oscillating&adjustment mechanism, electric control system, welding power source, etc.
