Product Overview
The **Heavy-Duty Steel Welding Table** is a modular, heavy-duty welding fixture platform designed for metal processing and heavy manufacturing. It features a Q345B high-strength alloy steel housing structure, undergoing artificial aging stress relief, CNC milling, and gas nitriding hardening. Equipped with a D16/D28 standard grid positioning hole system, it allows for the rapid assembly of various positioning pins, stops, and fixture components.
This steel welding table balances heavy load capacity, positioning accuracy, and flexible tooling expansion. It is suitable for single-piece, small-batch, and intermittent robotic welding operations, and supports multiple units to create a large working surface. It is widely used in welding and assembly operations for construction machinery, vehicle frames, sheet metal, and rail transportation equipment. Compared to cast iron welding platforms, it is lighter, has a shorter delivery cycle, and offers significant overall cost advantages, making it the preferred welding fixture solution for many metal processing plants worldwide.

Main features
✅ High Rigidity & Heavy-Duty Capacity: Welded box-type structure designed to withstand the weight of heavy workpieces and the impact of hammering or grinding.
✅ Modular Tooling: Standardized hole patterns accommodate clamps, positioning blocks, L-shaped stops, and quick-locking pins; eliminates the need for custom tooling and enables rapid production changeovers. 3D hole configuration allows for vertical and multi-angle workpiece clamping.
✅ Weld Spatter & Wear Resistance: Nitrided surface prevents weld spatter adhesion, making cleanup easy.
✅ Scalable & Expandable: Multiple platforms can be joined together to accommodate large steel structures.

Installation Steps
1) The floor must be high-strength concrete; soft flooring can lead to subsequent settlement and deformation.
2) Tighten bolts to the specified torque; do not overtighten using excessive force, as this can warp the table base.
3) Use a high-precision level to level the table in both directions, then lock the leveling foot nuts.
4) Install the grounding busbar and connect the welding return ground cable.
5) Re-verify flatness and hole-spacing accuracy using a laser level or straightedge.
> Important: Allow the Heavy-Duty Steel Welding Table to sit undisturbed for 24 hours after installation, then re-check flatness. Vibrations during transport may cause stress release in the tabletop, so accuracy should be confirmed again after this settling period.
