Foreword
This European Standard (EN 1011-6:2005) has been prepared by Technical Committee CEN/TC 121
“Welding”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by June 2006, and conflicting national standards shall be withdrawn at
the latest by June 2006.
This standard is composed of the following parts:
 Part 1: General guidance for arc welding;
 Part 2: Arc welding of ferritic steels;
 Part 3: Arc welding of stainless steels;
 Part 4: Arc welding of aluminium and aluminium alloys;
 Part 5: Welding of clad steel;
 Part 6: Laser beam welding;
 Part 7: Electron beam welding;
 Part 8: Welding of cast irons (prepared by CEN/TC 190).
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
Introduction
This standard is being issued in several parts in order that it can be extended to cover the different types of
metallic materials that will be produced to all European Standards for weldable metallic materials.
When this European Standard is referenced for contractual purposes the ordering authority or contracting
parties should state the need for compliance with the relevant parts of this standard and such other annexes
as are appropriate.
This European Standard gives general guidance for the satisfactory production and control of welding and
associated processes and details of some of the possible detrimental phenomena that can occur, with advice
on methods by which they can be avoided. It is generally applicable to laser beam processing of metallic
materials and also to some extent for non-metallic materials. It is appropriate regardless of the type of
fabrication involved, although the relevant product standard, structural code or the design specification can
have additional requirements. Permissible design stresses, methods of testing and inspection levels are not
included because they depend on the service conditions of the fabrication. These details should be obtained
from the relevant application standard or by agreement between the contracting parties.
It has been assumed in the drafting of the standard that the execution of its provisions is entrusted to
appropriately qualified, experienced and trained personnel.
