GB/T 22085.2-2008Electron and laser beam welded joints -- Guidance on quality levels for imperfections -- Part 2: Aluminium and its weldable alloys (English PDF)

Foreword

GB/T 22085 Electron and Laser Beam Welded Joints – Guidance on Quality Levels for

Imperfections consists of the following two parts:

--- Part 1: Steel;

--- Part 2: Aluminum and its weldable alloy.

This Part is Part 2 of GB/T 22085.

This Part equivalently adopts ISO 13919-2:2001 Welding – Electron and Laser Beam Welded Joints

– Guidance on Quality Levels for Imperfections – Part 2: Aluminum and its Weldable Alloys

(English Version).

This Part equivalently translated ISO 13919-2:2001. For the benefit of use, this Part made the

following editorial modifications:

--- Delete the Foreword of the international standard;

--- Change the standard name into Electron and Laser Beam Welded Joints – Guidance on

Quality Levels for Imperfections – Part 2: Aluminum and its Weldable Alloy;

--- For other international standards cited in ISO 13919-2:2001, if they are equivalently adopted

as Chinese standards, the corresponding international standards will be replaced by Chinese

standards;

--- Combine the "Instructions" of ISO 13919-2:2001 into Annex A.

The Annex A of this Part is informative.

This Part was proposed by and under the jurisdiction of National Technical Committee on Welding

of Standardization Administration of China.

Drafting organizations of this Part: Harbin Welding Institute.

Chief drafting staffs of this Part: Pu Dongguang, Wang Xuyou, Lei Zhen, and Wang Wei.

Electron and Laser Beam Welded Joints – Guidance on

Quality Levels for Imperfections – Part 2: Aluminum and Its

Weldable Alloys

1 Scope

This Part of GB/T 22085 specifies guidance on levels of imperfections in electron and laser beam

welded joints in aluminum and its alloys.

This Part applies to the aluminum and its alloys with thickness of 1mm above.
