Modular 3D Welding Workbench
Application:Welding&Assemble
Process:CNC Machining
Surface treatment:Normal/Nitrided
Type:3D
Brand:Lemar
Product Introduction
Our Modular 3D Welding Workbench is a multi directional hole grid platform built to simplify fixture setup for metal fabrication workshops. It adopts a full three dimensional hole layout on the top surface and all four side panels, allowing clamping and positioning from every side of the workpiece. The heavy welded steel base effectively absorbs welding vibration and reduces deformation caused by thermal stress. The workbench surface undergoes precise machining and nitriding treatment to enhance surface hardness and resist spatter damage. Standard hole spacing ensures full compatibility with a complete range of modular fixture accessories. Multiple workbenches can be connected together to expand the working plane freely to fit large or oversized metal structures.

Key Functional Advantages

Full three dimensional hole grid covers the tabletop and all four vertical sides, enabling multi angle clamping and flexible fixture arrangement for complex shaped workpieces. Operators can fix components from different orientations without repeatedly removing and repositioning heavy workpieces, which drastically cuts down fixture preparation time and improves overall workshop productivity for custom metal fabrication
The workbench tabletop and perforated side panels go through professional nitriding treatment after precision milling. This special surface treatment greatly raises the surface hardness, delivers strong resistance against welding spatter scratches and abrasive wear. It keeps the hole grid intact and maintains high positioning accuracy even after long term continuous use in harsh welding workshop environments.


Adopting universal D28 modular standard, this 3D workbench supports quick combination with various standard fixture accessories including locating pins side stops and quick release clamps. Multiple workbench modules can also be spliced seamlessly to build larger working platforms according to project requirements. It removes the need for time consuming custom fixture manufacturing and lowers your long term workshop tool procurement cost.
The heavy welded Q355 steel frame forms a rigid supporting structure with excellent anti deformation performance. Together with adjustable leveling feet installed at each leg, users can fine tune the platform flatness to adapt to uneven workshop floors. The solid structure can bear heavy workpieces steadily and absorb vibration generated during welding processes to guarantee stable assembly quality.

FAQ
Q1:What is the advantage of 3D hole layout compared with ordinary welding tables?
Holes on the top and four side faces enable clamping from all directions, which greatly reduces repeated workpiece repositioning.
Q2:Can we customize the size of this modular 3D welding workbench?
Custom sizes are available. Please send your workpiece size and load requirement for our technical proposal.
Q3:Does nitriding treatment cover the side faces of the workbench?
The top surface and all side panels with holes receive nitriding treatment to achieve uniform wear protection.
Q4:What accessories are compatible with this 3D welding workbench?
It matches D28 locating pins adjustable supports side stops quick release clamps and other standard modular fixture parts.
Q5:How to maintain the flatness of the 3D welding workbench during daily use?
Clear welding spatter and debris regularly. Avoid heavy impact or overloading to protect the precision machined surface.
Q6:How will you pack the workbench for ocean shipment?
We use reinforced export wooden cases with protective padding to prevent collision and surface damage during transportation.
