Aluminium Welding on Modular 3D Fixturing Tables: Best Practices
Aluminium Welding on Modular 3D Fixturing Tables: Best Practices
By NewWeldTable | Technique Guide Series
Unique Challenges of Aluminium
Aluminium’s thermal conductivity (4x that of steel) causes rapid heat dissipation. Its high thermal expansion coefficient makes it prone to distortion. Aluminium oxide melts at 2000 degrees Celsius vs the base metal at 660 degrees, requiring proper cleaning.
Why 3D Tables Excel for Aluminium
- Copper backing integration — Fit copper bars directly into the D28/D16 grid
- Multiple clamping points — Distribute clamping pressure evenly
- Soft-faced clamps — Copper-tipped clamps prevent surface marring
- Rapid repositioning — Switch between different profiles quickly
- Modular tooling — No dedicated jigs for different shapes
Copper Backing Bars
Copper backing bars are essential for aluminium welding. They absorb and dissipate heat rapidly, preventing burn-through on thin sections. Our copper bars with extended reach clamp into the grid, positioning directly behind the joint without interfering with the torch path.
Clamping Strategy
Aluminium’s softness requires care. Use clamps with copper or brass contact surfaces, or fit protective shims. Distribute pressure across multiple points. For thin-gauge aluminium, support the entire length with additional stops or risers to prevent sagging under heat.
