Purpose. This standard describes the general requirements, designs and tests concerning laser-welded joints where 2- and 3- pieces of sheet metal are joined and contains general information to the design of a laserwelded joint in case where detailed information is not stated on the drawings. Metallurgical aspects, e.g. grain size and hard-ness, are not considered. The criteria established in this standard become mandatory when referenced on a weld design document. Deviations from any weld criteria provided in this standard shall be identified on a weld design document.

Applicability. This standard is applicable to laser stainless steels and high strength low alloy (HSLA) steels with a carbon content of < 0.25 % (steels according to GMW2, GMW3032, GMW3399 and GMW14400).
