Why is there porosity within the weld metal when using my ESAB Welding System?
- GgnewmanAug 13, 2025
Porosity in the weld metal can occur due to several reasons: * The gas bottle might be empty. * The gas regulator might be closed. * There might be leaks or blockages in the gas inlet hose. * The wrong gas might be connected, or the gas flow might be incorrect. * The distance between the MIG torch nozzle and the work piece might be too large. * Drafts might be dispersing the shielding gas. * The work piece might not be clean, with oil or grease on the surface. Ensure the work piece is clean.
