Image's Stud Weldable Hydraulic Ports Provide Extremely Strong Welds onto Hydraulic Cylinders in Less than One Second
Image Industries, a leader in stud welding, announces that its stud weldable hydraulic ports allow far quicker, stronger welds onto hydraulic cylinders compared with the manual welding process. Image's stud weldable ports are easily welded onto hydraulic cylinders in less than one second compared with manual welding, which can take from one to several minutes. This dramatic time reduction will help hydraulic cylinder manufacturers increase their productivity and cut costs. The ports are suited for hydraulic cylinder manufacturers serving the general industrial equipment, construction, farm machinery, and off-highway equipment industries, as well as many other applications.
Stud weldable hydraulic ports permit a stronger weld with less heat distortion of the cylinder. The weld is structurally stronger because it is a full cross-sectional weld, which reduces failures and leaks, rather than the typical manual weld around the perimeter. Heat distortion in the cylinder is minimized due to the fast welding time, which prevents heat buildup within the cylinder. With less cylinder distortion, finishing operations are eliminated.
Image's stud weldable hydraulic ports are all customized in a wide variety of configurations and sizes to meet customer's specifications. Constructed of mild steel, they may be threaded internally or externally. Welding the ports onto the cylinders is performed using stud welding equipment, available from Image in a full array of handheld, robotic or customized designs in 1,200 or 2,000 Amp three phase units.

Hydraulic Port Welding Process Comparison
Stud Weld Cylinder Process
- Skive/Hone Cylinder
- An uninterrupted cut provides best finish and longest tool life.
- Cylinder easiest to handle with no weldments.
- Weld Port
- Weld time of .6 – 1 seconds. Saves $ by increasing throughput.
- Full cross-sectional weld, not a perimeter weld. Provides superior leak free results. Significant rework and $ cost reduction.
- One port fits a wide range of tube diameters. Fewer inventory items to stock and purchase.
- Small heat affected zone
- Drill & Chamfer
- Port can act as drill guide, making set up and tooling easier.
- Plug Weld Port
- Port Plug (only necessary on right angle fittings) can also serve as an air bleed, possibly eliminating another port saving additional $.
Traditional Cylinder Process
- Drill & Chamfer
- Weld Port
- Weld time of 20 – 60 seconds.
- Perimeter weld only which can be prone to leaks.
- Need to stock same boss with different radii to match different tube parameters.
- Large heat affected zone
- Skive/Hone Cylinder
- Possible hard spots from welding. Can increase cycle time and cause more frequent tool replacement increasing costs.
- Add Angle Fitting
- Consistent orientation may be a quality concern.
The stud weld process saves you $ from higher production speed, reduced rework (higher quality) and longer tool life.
