According to EN ISO 14731, “the coordination of manufacturing processes for all welding- related and welding- related activities” is defined as welding supervision . The person or organization that is responsible and competent for this is called the welding supervisor .
General
According to EN ISO 14731, the welding supervisory staff must have the appropriate general, technical and welding knowledge in order to be able to perform their tasks. These can be acquired through a combination of theoretical knowledge, training or experience. It is the responsibility of the manufacturer to define the requirements in such a way that the specific tasks can be performed by the welding supervisor in a qualified manner.
The standard: "The welding supervision - tasks and responsibility (ISO 14731: 2019); German version EN ISO 14731: 2019" defines the requirements as follows:
Comprehensive level
At the comprehensive level, the welding supervisory staff must have highly specialized problem-solving skills. These skills must include critical and initial assessment to determine and develop the best technical and economic solutions in applying welding and allied technologies to highly complex and unpredictable conditions. It must be able to handle and adapt the welding and related technologies for the manufacture of weldments, including highly complex issues. It must be able to make decisions and define and review welding-technological and welding-related personnel tasks.
Specific level
At specific levels, the welding supervisor must have advanced problem-solving skills. These skills need critical assessment to find suitable technical and economic solutions when applying welding technology and related technologies to complex and unpredictable conditions. It must be able to handle the application of welding and related technologies to the manufacture of weldments, including complex issues. It must be able to make decisions and define the welding-related and welding-related personnel tasks.
Basic level
At the basic level, welding supervisors must have basic problem-solving skills. These skills must include the ability to identify and develop appropriate solutions to common fundamental and specific problems using welding and related technologies. It must be able to monitor common or standard welding techniques and welding-related technologies, which are subject to minor changes, in foreseeable situations. It must be able to make decisions in common or standard work and to monitor the basic welding-related and welding-related personnel tasks.
International
According to international standards, the following training courses enable you to take over welding supervision in 53 countries without further examinations. Depending on the type and / or complexity of the production, welding supervisors are assigned to the following groups, whereby the International Association for Welding Technology (IIW) has specified recommendations for the minimum requirements for the training of welding supervisors. According to the European directive EWF 525-14, the trained welding supervisors for resistance welding are recognized throughout Europe.
Welding supervisor with extensive technical knowledge
- International welding engineer (SFI / IWE)
Unlimited tasks and responsibilities
Welding supervisor with special technical knowledge
- International welding technician (ST / IWT)
Tasks and responsibilities for a selected or restricted area
Welding supervision with basic technical knowledge
- International welding specialist (SFM, IWS, International Welding Specialist)
Tasks and responsibility for a restricted area of simple constructions
Practitioners with theoretical knowledge
- International Welding Practitioner (IWP) (SP / IWP)
Qualification for professional advancement to become a welding specialist
In-house welding supervisor
Internal activities are also fulfilled via the EWF Guideline EWF-652r3-14 / SV-00EWCP with the successfully passed tests for welding coordinators, the standard specifications such as ÖNORM EN 1090-2 according to international standards.
Welding supervision only for resistance welding
Welding supervisor trained in accordance with DVS-EWF 2941 limited to the processes of resistance spot welding, resistance projection welding and resistance roller seam welding.
Additional training
- Welding supervision rebar welding
- Welding supervision rail vehicle construction
- Welding supervision aluminum welding
- Welding supervision underwater welding
Recognition is only possible for "certified diver" or engineering diver in accordance with state regulations.
- Welding supervisor plastic pipes
Like an academic degree, the IIW diplomas are valid for life. With a certification that is valid for three years, further training and activity as a welding supervisor is certified for the first time three years after the award of the diploma in accordance with international standards. The certification of the welding coordinator (SAP) is not mandatory, but a corresponding IIW certificate facilitates the certification process according to DIN EN ISO 3834. The certification of a welding coordinator is carried out according to DIN EN ISO 14731 (Certified International Welding Engineer / Technologist / Specialist / Practitioner).
DIN EN 1090-2 requires, for example, for dynamically loaded components of class E as well as in the area of railway applications according to DIN EN 15085-2, training of the welding supervisor as a welding engineer.
Tasks and responsibilities of the welding coordinator
The tasks and responsibilities of the welding supervisor are specified in EN ISO 3834 "Quality requirements for fusion welding of metallic materials" depending on the requirements; the job description must be put down in writing. In EN ISO 3834-2 "Comprehensive quality requirements", all activities belonging to the area of responsibility of the welding coordinator, including the job description and the area of responsibility of the welding coordinator, must be documented in writing.
Review of requirements
The welding supervisor is responsible for checking the following requirements before starting work:
- the applicable product standard
- checking the manufacturer's ability to meet the requirements: B. the corresponding manufacturer approvals
Technical review and documentation
The technical test must be carried out during and before the start of production, including:
- Advice to the designer regarding the selection of the base material and suitable welding consumables
- Selection of welding processes and additives depending on the quality and acceptance requirements for the component
- Advice to the designer regarding the weldability of the construction and accessibility of the weld seams
- Definition of welding sequences and seam preparation
- Checking and determining the welding parameters based on welding instructions and work instructions to be created
- Creation of documentation in the required, requested or contractually agreed manner
- Technical review of the requirements for the welded construction
- Definition of the welding technology and the preparation of the weld seam, including the necessary pre- and post-treatment,
- Creation and review of welding instructions (WPS)
- Determination of the minimum size of fillet weld overlap patches for repairs, determination of the staggered arrangement for multi-part patches and rounded cutting of the kinked old material
- Chamfering of repair parts to avoid stress peaks and fractures under vibrating loads
- Supervision and supervision of the activities of the welding technicians who report to him,
- Training and exam preparation,
- Use of this personnel based on their qualifications and skills
- Monitoring the validity of the welder's certificates,

Welding engineer
Welding engineer (SFI) or International Welding Engineer (IWE) is an additional term for an engineer , the standard in international educational content in the fields of welding technology , material science , construction and manufacturing has demonstrated its expertise in testing. After passing the final examination, the trainee receives an internationally recognized diploma.
- Structure of the training
The training can be carried out in Germany at all welding technology teaching and research institutes (SLV) as well as some universities. In Austria, the internationally valid examination for welding supervision according to international standards can be taken at the WIFI . It is divided into three parts and four main areas: The two-year qualification tests and seam tests (welder test) are often part of vocational training. It does not matter who (e.g. DVS , TÜV , Germanischer Lloyd , Dekra ) has accepted the welder's test. Those who cannot produce any exams must take part in a welding internship in all welding processes.
- Part 1
- Main area 1: welding processes and equipment
- Main area 2: Materials and their behavior during welding
- Main area 3: construction and design
- Part 2: Practical Basics
- Part 3: Main course: Continuation of main areas 1 to 3 and additional
- Main area 4: Manufacturing and application technology
Participation in Part 1 can often be dispensed with if the content of Part 1 "Welding basics for engineers" has been conveyed through the completed engineering degree and this can be proven by a certificate issued by the university, technical school or professional academy.
