Fixing Porosity from Excessive Gas Flow

Excessive gas flow creates turbulence that draws atmospheric air into the weld pool, causing porosity. Reduce flow rate to 12-15 L/min and ensure laminar flow for proper shielding.

Solution Steps

  1. Reduce flow rate. Lower to manufacturer recommended settings, typically 12-15 L/min for MIG.
  2. Check for turbulence. Observe gas stream for smooth, laminar flow without disturbance.
Solution

CORGON® 18

Why proper flow matters: CORGON performs optimally at correct flow rates, providing excellent coverage without the turbulence that causes porosity.
