GB/T 34630.1-2017Friction stir welding -- Aluminium and its alloys -- Part 1: Terminology and definition (English PDF)

Foreword

GB/T 34630 "friction stir welding aluminum and aluminum" is divided into five parts.

--- Part 1. Terms and definitions;

--- Part 2. Welding joint design;

--- Part 3. Welding operators skills assessment;

--- Part 4. Welding procedure procedures and assessment;

--- Part 5. Quality and inspection requirements.

This section GB/T 34630 Part 1.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This section uses the redrafted law Amendment uses ISO 25239-1:2011 "Friction stir welding aluminum Part 1. Terms and definitions." this part of ISO 25239-1:2011 technical differences and the reasons are as follows.

--- Added tunnel hole definition (see 2.23);

--- Increasing the definition of the wrong side (see 2.24);

--- In order to facilitate the use and in line with industry custom, the terms in accordance with the method, the name of the tool, location, parameters, types, defects, test types Sorted again;

--- Added Hanyu Pinyin index.

This section also made the following editorial changes.

--- The standard name was changed to "friction stir welding aluminum and aluminum alloy Part 1. Terms and definitions";

--- Deleted the French and German ISO 25239-1:2011 corresponding terms;

--- Modify ISO 25239-1:2011 references;

--- Removed ISO 25239-1:2011 index French and German index.
