This internationally recognized standard defines the “quality requirements for fusion welding of metallic materials ” both in the workshop and on the assembly site.
To meet the needs of manufacturers, welding must be a “controlled process” by manufacturers. They can use this standard alone, or to complement their quality management system implemented by ISO 9001. The latter can be used to test the quality and strength of the weld after manufacture, but the defects identified cannot be corrected. To avoid this, the ISO 3834 standard integrates quality into the welding process itself, at the time of manufacturing a part.
In practical terms, manufacturers who comply with ISO 3834 are more competitive than others. Today, it is accepted not only in European countries, but also in the world. With the ISO 3834 certificate, companies have the opportunity to introduce themselves to new customers and markets. This of course allows them to optimize their welding process and reduce the risk of errors and thus costs. Having a quality management system for welding according to the ISO 3834 standard also allows them to enhance the value of the products they manufacture, to make the welding coordinator(s) accountable and to extend the validity of the Welder’s Qualifications.
A manufacturer can achieve quality assurance in welding without ISO 9001 certification. However, it is important to remember that according to the “hierarchy of standards”, ISO 9001 acts as a top reference to other specific standards that will complement it if necessary. [iheu_ultimate_oxi id=”9″]
ISO 3834 is integrated into several mandatory product standards. The latest is the NF EN 1090 standard for the manufacture of steel structures, which has been mandatory since July 2014. The ISO 3834 standard is also used in the railway sector (NF EN 15085), pressure equipment, boilers and piping as well as the transport of dangerous goods.
Now that we understand the usefulness of ISO 3834 and how it fits into the manufacturer’s quality assurance system, let’s define in broad terms what will be observed during the audit. In terms of welding, it is necessary to know how to qualify these 4 major themes: [iheu_ultimate_oxi id=”8″] During the audit, we can rely on other standards to define the qualified theme. For example:
During the ISO 3834 certification audit, the company must be able to provide evidence of the identification and traceability of the welding quality. Below, find the passage from the standard establishing the checklist of evidence to be provided. “Identification and traceability must be maintained throughout the manufacturing process, if required. Documented systems to ensure identification and traceability of welding operations shall include, if required:
Unless otherwise required, quality records must be retained for at least five years. The validity in duration of a certification is 3 years without changing the conditions of the certification.
SIRFULL WELDING is a browser-based software solution that allows you to track and record information and processes required by the ISO 3834 standard. Of course you don’t need to be ISO 3834 certified to use SIRFULL Welding. It is intended for manufacturers in all sectors of activity undertaking a certification process or simply wishing to apply all or part of the requirements of the standard.
Sirfull welding is adapted to“work with both French and international building codes, in a multi-code and multi-norm approach. “(cf. EMERSON PROCESS MANAGEMENT customer feedback).
In addition, the application is effective in automatically writing WPS qualified by a reference PQR, identifying welds on construction drawings or managing material and consumable certificates (e.g. CCPU); all of which are requirements of the ISO 3834 standard.
