Metal Material Welders
Throughout Italy, including at your premises.
Certification of welders according to UNI EN ISO 9606 for the permanent joining of pipes and plates with the following processes:
- Shielded Metal Arc Welding (SMAW)
- Gas Metal Arc Welding (MIG, MAG)
- Gas Tungsten Arc Welding (TIG, GTAW)
- Oxy-fuel Welding (OFW)
Certification is obtained by passing a practical examination, which attests to the skills in a specific process and for a given material group, as defined by the reference standards.
It is also possible to take the examination in English.
FAQ
I have an expiring certificate, what should I do?
From the validity start date, the Certificate, issued with revalidation method 9.3a), is valid for three years.
At the end of the 3 years, the Certificate will automatically expire, making it necessary to repeat the qualification exam.
What happens if the exam is not passed?
The candidate has the possibility to repeat the construction of a second joint during the exam session.
If the repetition is also not compliant, a training course will be necessary.
How is the certificate's validity field defined?
The validity fields are assessed based on the values of the essential variables indicated in the reference WPS by the examiner:
- Welding process;
- Base material;
- Geometric characteristics of the joints;
- Type of joint;
- Welding position;
- Consumables and filler material;
- Welding details.
The welder who passes the examination obtains a qualification certificate issued by TTR, an Accredited Certification Body UNI CEI EN ISO/IEC 17024.
What is WPS?
Welding Procedure Specification, which means welding procedure specification.
It is the document containing the welding procedure variables to ensure repeatability during the manufacturing stages.
The essential variables are:
- Welding processes and transfer modes;
- Product type (plate or pipe);
- Weld type (butt weld-BW and fillet weld-FW)
- Filler material group;
- Filler metal type;
- Dimensions
- Welding position;
- Welding details.
How to obtain qualification?
To obtain the qualification, the examination test is practical.
The test is carried out on samples with thicknesses and diameters selected according to the manufacturer's field of work as indicated by the reference WPS.
The samples will be subjected to visual inspection and laboratory tests as indicated by the standard itself.
What does standard UNI EN ISO 9606:2017 refer to?
The standard refers to the qualification tests of welders for fusion welding of steels. It provides a set of technical guidelines for a systematic welder qualification test so that the qualifications obtained are uniformly accepted, regardless of the type of product, the place and the examiner or examination body.
When qualifying welders, the focus is on the welder's ability to manipulate the electrode, welding torch or blowpipe, creating a weld of acceptable quality.
The standard applies to manual and semi-automatic fusion welding processes and does not cover automatic or fully automated processes.
