Certification of welders and brazers
Qualified welders and operators are essential for high-quality welds. Our experts provide you with all important welder qualification tests and help you to combine different certifications in one step. On behalf of DNV, we perform examination of welders and brazers as well as two- and three-year renewals according to:
- ISO 9606 (Manual welding)
- ISO 14732 (Operators)
- ISO 13585 (Brazers)
Over the years, Axess has provided our clients with more than 3000 certificates.
Qualification of welding procedures
In order for a welding procedure to be qualified, the process must be documented through testing and verification activities. For many years, Axess Group has supported clients in developing Welding Procedure Qualification Records (WPQRs), the documentation for welding procedure qualification, within a variety of construction environments. Our experience in material selection and welding processes enable us to develop both general and asset-specific WPQRs.
All welding procedures supplied through us are verified by DNV and we assist with qualification of welding procedures according to:
- ISO 15614
- DNV rules for welding
Welding inspections are conducted for several reasons, most commonly to determine whether the weld is of suitable quality for its intended application. Codes and standards developed specifically for a variety of welding fabrication applications are used during welding inspections to dictate what levels of weld discontinuities are acceptable.
With our team of certified welding inspectors, we perform welding inspections before, during and after welding according to applicable requirements and specifications.
Welding is a special process, which requires the coordination of welding operations in order to establish confidence in welding fabrication and reliable performance in service. The tasks and responsibilities of personnel involved in welding-related activities (e.g. planning, executing, supervising and inspection) should be clearly defined.
EN ISO 3834 is a standard that ensures that quality is maintained to achieve a well-functioning quality system in the execution of various welding applications. The standard defines three quality levels, depending on the type of weld performed.
The standard is currently used in most European countries. Nevertheless, there are many companies that have not yet seen the benefits of introducing a quality system according to this standard. Requirements may come from other standards as well as customers or authorities. Among others, both NS-EN 1090-2: 2018 and the standard for industrial piping system refers to EN ISO 3834.
We have a team with highly-skilled welding engineers that are certified according to IIW guidelines on IWT and IWE levels. They are able to provide coordination services for any given welding fabrication work and at any level specified within EN ISO 3834.
