Auto Cylinder End Caps Circular Seam Welding Machine

In hydraulic systems, the quality of the circumferential weld between the cylinder barrel and the cylinder bottom directly determines the cylinder's pressure resistance, lifespan, and safety. The MAG cylinder circumferential welder is specifically designed for hydraulic supports, engineering machinery cylinders, and high-precision thick-walled cylinder barrels. It employs a gas metal arc welding (GMAW) process, achieving single-sided welding with double-sided forming.

This equipment solves the problems of porosity, cracks, and weld misalignment inherent in traditional manual welding. Through digital control and a high-rigidity mechanical structure, it ensures uniform weld seams and consistent penetration depth, meeting the stringent standards of high-pressure sealing.

• Welding machine bed: Constructed from high-quality carbon steel and subjected to stress-relief annealing to ensure no deformation during long-term use.

• Spindle power system: Servo motor driven, coupled with a precision reducer, providing high torque output to overcome the resistance during welding of thick-walled tubes.

• Welding execution system: Includes an oscillator, welding torch holder, and three-dimensional fine-tuning support to adapt to different weld widths.

• Electrical control system: PLC (Programmable Logic Controller) + touch screen human-machine interface, capable of storing multiple sets of welding process parameters.

• Auxiliary support system: self-centering rigid roller frame or pneumatic tailstock to prevent sagging due to gravity during welding of long hydraulic cylinders.

This model is a standard piece of equipment in the hydraulic and pneumatic industries, primarily used in:

• Construction machinery: excavator boom cylinders, loader boom cylinders, crane outrigger cylinders.
• Mining equipment: hydraulic support columns, jack cylinders.
• General machinery: large press cylinders, injection molding machine mold locking cylinders.
• Vehicle manufacturing: dump truck lifting cylinders, sanitation vehicle compression cylinders.
