Welding. Laser-arc hybrid welding of steels, nickel and nickel alloys. Quality levels for imperfections1 Scope This International Standard specifies quality levels of imperfections in laser arc hybrid welded joints for all types of steel, nickel and its alloys. It applies to material thickness 0,5 mm. Three quality levels are given in order to permit application for a wide range of welded fabrication. They are designated by B, C and D. Quality level B corresponds to the highest requirement on the finished weld. The quality levels refer to production
