Three-Jaw Self-Centering Gripper Welding Chucks
• It is a clamping device commonly used in welding automation, tank fabrication, pipe welding, and positioning systems.
• A chuck with three jaws that move simultaneously when adjusted.
• Designed to self-center the workpiece (pipe, flange, or round component), ensuring concentric clamping.
• Usually mounted on welding positioners, head and tail stocks
• Irizar Chucks are designed for welding at low speeds, not for use on a lathe at high speeds.
Three-Jaw Self-Centering Welding Gripper Chucks
Model 3J-615-1T: 85 to 615 mm Ø
Model 3J-1080-1T: 85 to 1,080 mm Ø
Model 3J-1250-2T: 200 to 1,250 mm Ø
Model 3J-1500-3T: 200 to 1,500 mm Ø
Key Features:
• Self-Centring Action: All jaws move together, automatically aligning the workpiece with the chuck’s axis.
• High Clamping Force: Strong grip for holding pipes, tanks, shafts, and circular parts during welding.
• Quick Setup: Faster workholding compared to independent jaws.
• Adaptability: Jaws can be swapped between internal (ID) or external (OD) gripping.
• Sizes: Range from small to large diameters
Welding Applications:
• Pipe to flange welding
• Tank nozzle welding
• Round workpiece alignment on positioners
• Automation setups for repetitive jobs
Advantages:
• Accurate centering
• Reduces setup time
• Secure clamping during rotation/welding
• Durable for heavy fabrication
