ISO 9606-2:2004 specifies the requirements for qualification of welders for fusion welding of aluminium and aluminium alloys. ISO 9606-2:2004 provides a set of technical rules for systematic qualification of welders, which are independent of product type, location and examiner/examining body. The welding processes referred to in ISO 9606-2:2004 include those fusion welding processes which are designated as manual or partly mechanized welding. It does not qualify fully mechanized and automated welding processes.
