DIN EN ISO 12932:2013-10

This International Standard provides quality levels of imperfections in laser-arc hybrid welded joints for all types of steel, nickel and its alloys. Three quality levels are given in order to permit application for a wide range of welded fabrication. They are designated by symbols B, C and D. Quality level B corresponds to the highest requirements on the finished weld. The quality levels refer to production quality and not to the fitness-for-purpose of the product manufactured.
