How to prevent deformation of the 3D welding table surface?

Key Methods to Prevent Deformation

Choose the right material & thickness

Use high-strength, heat-resistant cast iron or thick steel plates for the table surface.

Increase plate thickness to improve rigidity and resist thermal deformation.

Control welding heat input

Avoid long-time, high-heat concentrated welding on one area.

Use lower current, shorter arc time, and intermittent welding to reduce local overheating.

Adopt reasonable welding sequence

Weld from the center outward or use symmetrical welding to balance internal stress.

Use step-by-step, segmented welding instead of continuous long passes.

Preheat & slow cooling

Properly preheat the table surface before heavy welding to reduce temperature difference.

Let it cool naturally after welding; do not cool quickly with water.

Reinforce the structure

Add stiffeners, ribs, or support beams under the table surface to enhance overall rigidity.

Ensure the supporting frame is stable and evenly stressed.

Avoid overloading & impact

Do not place excessively heavy workpieces or drop heavy objects violently on the table.

Distribute large workpieces evenly instead of concentrating load on one spot.

Stress relief treatment

For precision tables, use vibration stress relief or heat treatment to eliminate welding residual stress.
