Product Description
3 Jaw 4 Jaw Welding Chuck for Welding Positioner Turntable
Product Overview
3-Jaw and 4-jaw chucks are dedicated fixtures for welding positioners. The 3-jaw self-centering model delivers fast clamping for round pipes and cylinders. The 4-jaw independent-adjust type fits square, rectangular and eccentric irregular workpieces. Both realize 360° synchronous rotation with positioner turntable, providing steady non-slip clamping and high precision for circumferential welding.
Main Advantages
- Dual-type for broad usage - Two styles cover round, square and irregular workpieces, solving most clamping requirements for pipe and cylinder welding.
- Precise and firm clamping - High-frequency quenched jaws offer high hardness and friction to stop shake and slip during rotary welding for consistent weld quality.
- High rigidity & long service life - Stress-relieved cast steel body resists deformation and wear, ideal for continuous heavy-duty industrial welding.
- Quick installation & simple operation - Standard flange mounting fits most positioners. Manual adjustment is user-friendly with no complicated training.
- Rich custom options - Support large bore, special flange, extended jaws and soft protective jaws for thin-wall, stainless steel and special-shape workpieces.

Application Scope
- Round Pipe & Cylinder Welding - 3-jaw chuck is widely used for stainless steel pipes, carbon steel pipes and cylindrical tank shell clamping and circumferential welding.
- Square & Special-shaped Workpiece Welding - 4-jaw independent chuck perfectly clamps square tubes, rectangular frames and eccentric irregular workpieces that 3-jaw chucks cannot fix.
- Tank & Nozzle Welding - Suitable for tank nozzle, pipe fitting and end face welding, improving welding tightness and appearance quality.
- Mechanical Hardware Processing - Used for batch clamping and welding of cylindrical and special-shaped mechanical accessories and hydraulic parts.
- Automatic Welding Line Matching - Perfectly matched with welding positioners to form automatic rotary welding system, improving production efficiency and automation level.
Precautions
- Reasonable Model Selection - Choose 3-jaw chuck for regular round workpieces for fast centering; choose 4-jaw chuck for square and irregular workpieces to ensure clamping stability.
- Forbid Overload Clamping - Do not clamp workpieces beyond the rated clamping range. Overload will cause jaw deformation and accuracy loss.
- Uniform Clamping Adjustment - For 4-jaw chuck, adjust four jaws evenly to avoid eccentric clamping and rotary vibration.
- Operation Safety Rules - Do not adjust jaws or touch rotating workpiece during machine operation. Stop equipment completely before adjustment.
- Welding Spatter Prevention - Regularly clean welding spatter on gear and jaw gaps to avoid jamming and transmission failure.

Frequently Asked Questions
Q1: What is the difference between 3-jaw and 4-jaw welding chuck?
A: 3-jaw is synchronous self-centering type, fast positioning for round and symmetrical workpieces. 4-jaw is single-jaw independent adjustment type, suitable for square, eccentric and irregular workpieces.
Q2: Can 4-jaw chuck clamp round pipes?
A: Yes, it can clamp round workpieces, but manual fine-tuning of each jaw is required to ensure concentricity.
Q3: Will the hard jaws scratch stainless steel workpieces?
A: Standard hard jaws are for ordinary carbon steel. We provide optional soft protective jaws to protect thin-wall and stainless steel surfaces.
Q4: Is the chuck compatible with all brands of positioners?
A: Yes. We can customize flange size and mounting hole spacing to match most mainstream welding positioners.
Q5: Does the chuck support 360° synchronous rotation?
A: All models support full 360° smooth synchronous rotation with positioner turntable without jamming.
Q6: Can you customize large bore and special size?
A: Custom service is available. We support large bore, ultra-thin body, extended jaws and non-standard installation size customization.
