When should a visual inspection of weld seams be conducted?

The manufacturer is obligated to perform a visual inspection of all weld seams as soon as a quality standard for weld inspection is applicable. The manufacturer must visually check if there are any quality defects in the welds of their product.

Quality management standards for welds

A visual inspection of all weld seams is systematically required once a welding quality management standard is demanded for the work to be performed. Welding defects must therefore be visually controlled. Examples:

  • ISO 3834
  • EN 1090-2
  • EN 15085
  • ISO 9001
  • PED
