Why are my Air Liquide Welding System welds porous or spongy?
- KKatherine ReyesJul 31, 2025
Porous or spongy welds in your Air Liquide Welding System can be caused by several issues. First, ensure you have an adequate gas supply and pressure. If there are drafts in your welding area, use a screen and increase gas delivery pressure if needed. Clogged holes in the gas diffuser can also cause this issue, so clear them with compressed air. Check for gas leaks in the supply hoses and replace any faulty components. Additionally, a blocked solenoid valve can be the culprit; check its operation by removing the hose connecting the pressure regulator to the power source. Finally, poor quality gas or wire can lead to porous welds, so ensure your gas is extra-dry and consider changing the cylinder or using a different type of wire.
