Approval of a welding procedure specification (WPS) for the production arc welding of steel castings is specified. Conditions for the execution of welding procedure approval tests and the limits of validity of an approved welding procedure are defined. The principles set out here may be applied to other welding processes under certain circumstances. Design of welded test pieces, location of test samples, the extent of testing for specified test methods, and requirements to be followed for destructive and nondestructive testing are set out. A grouping system is presented for cast steel and nickel alloy parent metals, in order to minimise the number of welding procedure tests needed. Limits to the approval on the basis of welding process, welding position, type of joint, filler metal, type of current, heat input, preheat temperature, interpass temperature and post weld heat treatment are explained. Special cases for MMA, FCA, submerged arc, MIG, MAG and TIG welding are listed.

[in French]

A welding supervisor for Alstom Transport offers advice on how a company can achieve certification for its quality assurance system. This is important since France lags somewhat behind the rest of Europe in this field. Details are given of how to set up an audit. Then documentation is needed for organising the welding quality system, and this is done in four levels: management of the welding procedure, general welding conditions of the constructor, specific welding conditions in the market, and instruction cards and documents relative to welding. These are all illustrated with tabulated explanatory data. None of these requirements should present unsurmountable difficulties and a certified system is important to all clients and has international standing.

[in Italian]
(Paper presented at IIS Day of Training and Updating "Innovations in the Welding of Light Alloys", Montichiari, Italy, 18 May 2006)

The study concentrates on the situation of standardisation in Europe of qualification of welders and welding processes, especially in the case of aluminium alloys. The standards covering welding processes come under the Italian, European and International Standards UNI EN ISO 15609 and UNI EN ISO 15614-2-2006. The latter deals mainly with MIG, TIG and plasma welding, though others may be taken into consideration. Data on the required tests are tabulated along with illustrations. Welding personnel can be qualified under UNI EN ISO 9606-2:2006. The certificate is valid for two years, and if the welder is still working after six months then an extension for a decade is applicable. Welding operatives may be qualified under UNI EN 1418 for manual and semiautomatic welding. This is widespread throughout Europe.

[in English]

A hybrid laser-plasma welding head which feeds in the filler material in powder form was developed; experiments were carried out to investigate the effects of welding parameters and to establish a parametric window for a stable welding process. The experiments were carried out on high alloy austenitic steel (1.4306, 1.4565) and nickel alloy 617 sheet/plate of thickness 3-8 mm. The effects of focal position, amperage, welding speed and geometrical arrangement of the laser beam in relation to the plasma torch were investigated for PA, PF and PG welding positions. Both Nd:YAG and CO2 lasers were used and the resulting welds were evaluated.

[See BS EN ISO 15614-1: 2004; Weldasearch 214339]

The ranges of qualification associated with welding process variables, welding position, energy input and heat transfer are briefly discussed with reference to standard UNE EN ISO 15614-1, which follows the same philosophy as the earlier UNE EN 288-3. The qualification obtained is valid solely for the welding processes used in the welding procedure test, which in practice may be a single process or a combination such as TIG root welding followed by MMA welding with basic electrode; in the latter case, there may be one multiprocess test or two independent ones, but the processes are not qualified for single use, only for multiple use in the developed sequence. The standard was established expressly to allow independent qualification of each degree of mechanisation.

It is one of a series of standards and gives specific requirements which extend the general specification and qualification rules in BS EN ISO 15607 applicable to qualification based on tested welding consumables used in plasma welding, gas welding and a range of arc welding processes to weld alloys based on steel and on aluminium. It gives requirements for the welding procedure qualification including range of qualification, validity and welding procedure qualification record (WPQR).

[in English]

A discussion is presented on the quality management system model for welded structures based upon EN 729 ("Quality requirements for welding - Fusion welding of metallic materials"), looking at the quality requirements set out and the European certification system for welding producers. The three levels of quality requirements (comprehensive, standard, elementary) set out in EN 729 and their applicability to the different elements within actual manufacturing (such as welders, welding coordinators) are discussed. The main elements of the European certification system for welding producers, which is based on EN 729, are described and the network of certification bodies of the European Welding Federation is discussed. The issue of combining EN 729 certification procedures with certification of environment management systems is discussed.

This British, European and International Standard specifies requirements for the welding procedure test in the qualification of welding procedures for the arc welding of tube to tube-plate joints in metallic materials by manual, partly mechanised, mechanised or automatic processes. Requirements are stated for the preliminary Welding Procedure Specification (pWPS), the qualification of welding procedure and welding of test pieces. Examination methods and appropriate acceptance levels are given and the validity of a range of qualification conditions is specified. Requirements for issuing a Welding Procedure Qualification Record (WPQR) are set out and an example given in an informative annex.
