The line of pores in the welded seam.

The line of pores in the welded seam occurs because of low current, high weld speed and irregular gas feed or high humidity.

The line of pores is a minor defect. The repair is regulated by the regulative documents on welding.

On the picture the line of pores is visible in the form of the black points located in a straight line.
