CNC Single Torch Circumferential Welder For Hydraulic Cylinder

Its core working principle typically employs a "workpiece rotation, welding torch fixed" approach. Through a PLC (Programmable Logic Controller) combined with servo drive technology, the workpiece is controlled to rotate at a uniform speed, while the welding torch performs wire feeding, arc initiation, and oscillation actions, thus completing a full circle or multiple layers/passes of automatic welding.

1.Clamping and positioning mechanism: Includes a three-jaw chuck, a pneumatic tailstock, and a center rest. One end of the workpiece is clamped by the spindle box chuck, and the other end is held in place by the pneumatic tailstock center, ensuring concentricity during workpiece rotation. The center rest presses the workpiece to prevent welding deviation.

 

 

 

2.Welding actuator (head): Equipped with a welding torch, featuring three-dimensional adjustment (up/down, left/right, forward/backward). It includes a oscillator to allow the welding torch to swing left and right to fill the bevel. Additionally, an up/down lifting mechanism precisely controls the vertical position of the welding torch to accommodate workpieces of varying thicknesses and welding process requirements.

3.Electrical control system: A PLC is used as the core control unit, coupled with a human-machine interface (touchscreen). Operators can preset welding speed, number of revolutions, oscillation parameters, and advance/delay gas supply/shutdown time via the screen.

4. Others for your reference 

• Hydraulic Industry: Circumferential welding of hydraulic cylinder bodies, flanges, and cylinder bottoms; welding of piston rods to end caps.
• Construction Machinery: Crane outrigger cylinders, loader steering cylinders, mining machinery, etc.
• Automotive Parts: Shock absorber reservoir cylinders, drive shafts, steering gear assemblies, etc.
• Other Fields: Circumferential welding of various pressure vessels, air tanks, fire-fighting equipment cylinders, and long pipe joints.

1.Normally we will use fumigation plywood case for packaging; for some big machine, we can use steel pallet and plastic filme cover.All machines are paint with anti rust paint or oil before leaving factory.
2.Package can be as customers' requirement.
