few know the secret trick of welding galvanized square pipes | Welding

Welding galvanized square tube requires specific precautions due to the zinc coating, which can produce hazardous fumes when heated.
Remove Galvanization: Grind off the zinc coating around the area to be welded. Use a wire brush or grinder to expose the bare metal. This reduces the production of toxic fumes and improves weld quality.
Clean the Surface: Clean the exposed metal with a solvent to remove any oil, dirt, or residue that might interfere with the weld.
Set up the Welding Machine: Adjust the settings on your welding machine according to the material thickness and the type of welding process you are using.
Weld in Short Bursts: Use short welding bursts to minimize heat build-up, which can cause warping and additional zinc fumes. Allow the metal to cool slightly between welds.
Maintain Consistent Speed: Ensure a consistent travel speed to avoid burn-through and ensure a smooth, even weld.
