EN ISO 17660-1:2021 - A Comprehensive Guide

Introduction

EN ISO 17660-1:2021 is a European Standard that outlines the requirements for the resistance spot welding of aluminum and aluminum alloys. This standard is part of the ISO 17660 series, which provides guidelines for the spot welding of aluminum and its alloys. In this guide, we'll walk you through the key aspects of EN ISO 17660-1:2021, its significance, and its applications.

Scope and Application

EN ISO 17660-1:2021 applies to the resistance spot welding of aluminum and aluminum alloys, including: en iso 17660-1 pdf

1. Automotive industry
2. Aerospace industry
3. Construction industry
4. Other industries where aluminum and its alloys are used

This standard covers the welding of:

• Aluminum alloys (5000, 6000, and 7000 series)
• Aluminum sheets and plates with thicknesses ranging from 0.5 mm to 6 mm

Key Requirements

EN ISO 17660-1:2021 sets out the following key requirements:

1. Welding Process: The standard specifies the requirements for resistance spot welding (RSW) using a direct current (DC) or alternating current (AC) welding machine.
2. Equipment: The standard outlines the requirements for welding equipment, including electrodes, welding machines, and control systems.
3. Material Preparation: The standard specifies the requirements for material preparation, including surface cleaning, degreasing, and storage.
4. Welding Parameters: The standard provides guidelines for setting welding parameters, such as welding current, voltage, and time.
5. Inspection and Testing: The standard requires inspection and testing of welds, including visual inspection, destructive testing, and non-destructive testing.

Quality Requirements

EN ISO 17660-1:2021 emphasizes the importance of quality control and assurance. The standard requires:

1. Welding Procedure Specification (WPS): A WPS must be established and qualified before production welding.
2. Welder Qualification: Welders must be qualified and trained according to the standard.
3. Quality Control: A quality control system must be implemented to ensure compliance with the standard.

Benefits and Significance

EN ISO 17660-1:2021 offers several benefits, including:

1. Improved Quality: The standard ensures consistency and quality in the welding of aluminum and its alloys.
2. Increased Safety: The standard promotes safe welding practices and reduces the risk of accidents.
3. Enhanced Efficiency: The standard streamlines welding processes, reducing production time and costs.
4. International Recognition: The standard is recognized globally, facilitating international trade and cooperation.

Obtaining the Standard

You can obtain a copy of EN ISO 17660-1:2021 from:

1. ISO Online Library: The official ISO online library offers a digital version of the standard.
2. National Standards Bodies: National standards bodies, such as ANSI (American National Standards Institute) or BSI (British Standards Institution), may also offer copies of the standard.
3. Online Marketplaces: Online marketplaces like IHS Markit, Techstreet, or ASTM Compass may offer digital or printed copies of the standard.

By following the guidelines and requirements outlined in EN ISO 17660-1:2021, manufacturers and welders can ensure high-quality welding of aluminum and its alloys, ultimately leading to improved product performance, safety, and reliability.

2. Key Technical Requirements

How to Use This Standard Effectively

If you have access to the document, here is a workflow for applying it to your project:

1. Define the Welding Procedure Specification (WPS): Use the parameters in the standard to write your WPS before welding begins.
2. Check Qualifications: Cross-reference the welder's certificates (Clause 6) to ensure they are valid for the specific rebar diameter being used.
3. Perform Visual Inspection: During production, use the PDF on your device to zoom in on diagrams showing acceptable weld profiles versus defective ones.
4. Sampling Protocol: Refer to the standard’s sampling rules to determine how many test specimens you need to pull from a batch of welds to satisfy quality control.
