GB/T 19869.2-2012Welding procedure qualification test for aluminum and its alloys (English PDF)

Foreword

This standard rule according to GB/T 1.1-2009 given draft.

This standard uses redrafted Law Amendment uses ISO 15614-2:2005 "metallic materials and welding procedure qualification of welding technology assessment Setting test - Part 2. Arc welding of aluminum and its alloys "(in English).

This standard ISO 15614-2:2005 and its main technical difference between the following reasons.

--- Clear all kinds of imperfections qualified grade requirements in order to operate;

--- Add additional tests dissimilar aluminum joint assessment to meet the needs assessment;

The format and content --- Process Evaluation report combined with our practical application have been adjusted to facilitate the implementation.

For ease of use, this standard at the time of conversion to international standards made the following editorial changes.

--- Deleted international standards foreword;

--- The ISO 15614-2. ISO 2005 standards referenced in place of using the corresponding standard.

This standard by the National Standardization Technical Committee welded (SAC/TC55) and focal points.
