The pore cluster

The pore cluster at the root of weld occurs because of the low current, high weld speed and irregular gas feed and lack of welding shielding against intake of moisture.

The pore cluster is a minor defect. The repair is regulated by the regulative documents on welding.

On the picture the pore cluster is visible in the form of the black points located without specified procedure.
