Product Description
V-shaped positioning block for 3D welding table
- V-groove opening: Mainstream angles are 90°/120°/130°/135°. 90° offers high centering accuracy for small to medium-sized round tubes; 120°/130° provides a larger and more stable contact area, suitable for large diameter tubes or heavy loads.
- Bottom positioning structure: Equipped with D16 (φ16) or D28 (φ28) standard positioning holes, fixed to the welding platform grid holes (50/100mm spacing) via positioning pins/locking pins. It can be installed in any position with a repeatability accuracy of ±0.02mm.
- Material and hardness: High-strength alloy steel/40Cr, surface hardened to HRC45-50, wear-resistant, deformation-resistant, and resistant to welding spatter damage.
- Working principle: Utilizing the self-centering characteristic of the V-groove, after the cylindrical workpiece is placed, the axis automatically aligns with the V-center, and it can be fixed with the clamping device without complex adjustments.

Functions and Advantages
- Precise Centering: The symmetrical V-groove design automatically centers cylindrical workpieces, solving the problems of eccentricity and misalignment in round pipe welding and ensuring coaxiality.
- Flexible Adaptability: Compatible with 3D welding table D16/D28 hole systems, it can be used individually or in pairs, combined in any position, and adapted to pipes of different lengths and diameters.
- Efficient Clamping: No need for customized special tooling, quick positioning and clamping significantly reduces clamping time and improves welding efficiency.
- Stable Support: The large-angle V-groove (120°/130°) provides a large contact area, preventing slippage and rolling, and resisting deformation under welding stress.
- Durable and Economical: Made of hardened alloy steel, it is high-temperature resistant, spatter resistant, wear-resistant, and reusable, reducing long-term costs.
Load and Operating Conditions
The overall structure is thickened and reinforced, ensuring it remains undeformed under heavy loads and can support heavy round pipes, shafts, and mechanical fittings.
Suitable for frequent use in workshops such as cold working welding, steel structure welding, vehicle frame welding, pipe prefabrication, and engineering machinery tooling.
Resistant to weld slag, impacts, and repeated disassembly and assembly, its service life is several times that of ordinary spacers.
Process and Surface Treatment
The body is made of integral forging and precision milling, not ordinary cast iron, making it less prone to breakage and deformation.
High-precision CNC milling of V-grooves ensures a smooth, burr-free contact surface and high repeatability.
Mainstream processes: Integral nitriding, blackening, galvanizing
- Nitriding: High hardness, resistance to welding spatter, high temperature resistance, rust and corrosion resistance; the first choice for high-frequency welding in factories.
- Blackening/galvanizing: High cost-effectiveness, suitable for ordinary light-load welding conditions.
