National foreword

This British Standard is the official English language version of EN 1011‑4:2000, including amendment A1:2003. It supersedes BS 3019‑1:1984 and BS 3571‑1:1985 which is withdrawn.

The UK participation in its preparation was entrusted to Technical Committee WEE/28, Inert gas arc welding, which has the responsibility to:

aid enquirers to understand the text;
present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed;
monitor related international and European developments and promulgate them in the UK.

A list of organizations represented on this committee can be obtained on request to its secretary.

Introduction

This European Standard has been issued with several annexes in order to cover aluminium and the different types of its alloys in all forms which will be produced to the relevant European standards.

In this standard the term aluminium stands for aluminium and its alloys.

This standard gives general guidance for the satisfactory design, production and control of welding and details the possible detrimental effects which may occur, together with advice on methods by which they may be avoided. Generally it is applicable to all types of aluminium materials and is appropriate regardless of the type of fabrication involved, although the application standard/contract may have additional requirements.

Permissible design stresses in welds, methods of testing and acceptance levels are not included because they depend on the service conditions of the fabrication. These details should be obtained from the design specification.

Informative annexes give information on detrimental effects (see annex A) and choice of consumables (see annex B).

This document details only welding related matters and does not give any details of mechanical properties of the welded joint.

This standard identifies the main factors that affect the welding of aluminium. This will be influenced by parent metal, consumables, design, welding procedure, welding equipment, joint preparation etc.

General requirements for fusion welding of metallic materials are detailed in EN 1011‑1, in particular:

tack welds;
temporary attachments;
arcing;
inter-run cleaning and treatment;
welding procedures;
identification;
inspection and testing;
quality requirements;
correction of non-conformity;
distortion;
post-weld heat treatment;
abbreviations and symbols;
run-on/ run-off plates.

1 Scope

This European Standard gives general recommendations for the manual, mechanized and automatic fusion welding of wrought and cast aluminium alloys and combinations thereof.

For general guidelines, see EN 1011‑1.

In this standard the word "pipe" alone or in combinations is used to mean "tube" or "hollow section", although these terms are often used for different categories of product by different industries.
