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.
