ISO 15609-5:2011

ISO 15609-5:2011 specifies requirements for the content of welding procedure specifications for resistance spot, seam, butt and projection welding processes. It is necessary to establish the acceptability of applying the principles of ISO 15609-5:2011 to other resistance and related welding processes before any qualification is undertaken. Variables listed in ISO 15609-5:2011 are those influencing either weld dimensions (quality), weld nugget dimension, weld pattern positioning, mechanical properties or geometry of the welded joint.
