Pins and Prisms

Pins and V-blocks for welding tables are key clamping system components that enable stable, repeatable, and precise positioning of structures during welding. Combined with POS-MET system tables, they create a modular work environment that allows for building both simple and complex assembly configurations. The use of pins and V-blocks significantly improves weld quality, ergonomics, and workplace safety, regardless of whether welding is performed using the MIG/MAG or TIG method.
Welding pins – stabilization and precise clamping
Welding pins are mounting components designed for locking and positioning accessories within the system holes of a welding table. They provide secure, multi-point clamping essential for maintaining structural stability and setup repeatability.

POS-MET pins perform exceptionally well when working with structural steel, where high strength and heavy-load resistance are required. In 3D systems, they act as connectors between the table and accessories, while quick-locking pins allow for instant configuration changes without additional tools, boosting ergonomics and speeding up the assembly process.

Thanks to the precise manufacturing of the pins, it is also possible to mitigate thermal deformation that may occur when the material heats up. Securely clamping the workpiece minimizes the risk of movement during welding.
Welding V-blocks – height adjustment and 3D positioning
Welding V-blocks are multidimensional spacer blocks that significantly expand workstation configuration options. They allow for elevating workpieces, adjusting their angle, and creating multi-level assembly setups on a modular table.

They are used in both 2D and 3D configurations, allowing them to serve as spacers, supports, or positioning elements for workpieces with varying geometries. This is particularly important in processes requiring maximum precision, such as TIG welding, where perfect workpiece alignment is critical for weld quality.

V-blocks are particularly useful when working with deformation-prone materials such as aluminum, as they enable multi-point support and even stress distribution.
Modular 3D system and workplace ergonomics
A 3D welding table combined with pins and V-blocks creates a modular clamping system that quickly adapts to the geometry of the welded element. This flexibility enhances workstation ergonomics, allowing the welder to work in a comfortable position without the need for improvised supports.

In mass production, 3D systems enable repeatable positioning of elements, which speeds up the assembly process and improves the efficiency of the entire production cycle.
