Extensions and Supports

Welding table extensions are a modular expansion of the work surface, allowing you to increase mounting space and adapt the table to larger-scale projects. It is an ideal solution wherever the standard table surface is insufficient and stable, secure clamping of larger steel or aluminum components is required. Thanks to compatibility with POS-MET system grid bores, the extension can be quickly mounted to create a seamless, solid work surface.
Welding table module – flexible system expansion
The table extension functions as a welding table module that integrates seamlessly with a 3D system platform or a traditional workbench. It enables 3D layout configurations, expanding the tabletop along the length or width axes, and building custom setups tailored to specific project requirements.

In POS-MET systems, extensions are mounted using fast-locking bolts, ensuring a rigid, repeatable, and secure connection between components. For heavier loads, additional welding table supports are utilized to prevent deflection and increase the overall load capacity of the structure.
Welding table extension – larger surface area, greater possibilities
Thanks to the extension block, you can easily extend your welding table, which is especially important when working with long profiles, frames, steel structures, and components that require full-length support.

In practice, table extensions are used, among other things, for:

working with large structural steel components,
stably supporting lightweight aluminum components susceptible to deformation,
assembly work where free access and precise angle positioning are essential,
repeatable batch production requiring consistent setup geometry. 

Additional components, such as welding V-blocks (prisms) or 3D spacer blocks, allow you to extend the functionality of the extension, enabling height adjustment, creating multi-level setups, and facilitating advanced welding positioning.
Welding table top plate – stable and compatible surface
Each extension is based on high-quality welding table top plates that match the specifications of the main tabletop. This guarantees system consistency, a level surface, and stability during assembly. Heavy-gauge sheet metal with precise bore geometry enables the full range of POS-MET accessories to be utilized, including fast-locking bolts, V-blocks, and spacer blocks.
Precision, ergonomics, and safety at work
An expanded table surface increases assembly precision by allowing components to be easily aligned along the construction axis, eliminating the need for temporary detail support. This reduces setup time, improves positioning repeatability, and facilitates the execution of high-quality welds.

A larger work area also enhances welding station ergonomics, providing the welder with more room to work, improved access to components, and safer tool handling.

Using an extension block also reduces the risk of thermal deformation, as components can be supported over a greater length and stabilized at multiple points.
