When should a visual inspection of weld seams be conducted?

The manufacturer is obligated to perform a visual inspection of all weld seams as soon as a quality standard for weld inspection is applicable. The manufacturer must visually check if there are any quality defects in the welds of their product.

Quality management standards for welds

A visual inspection of all weld seams is systematically required once a welding quality management standard is demanded for the work to be performed. Welding defects must therefore be visually controlled. Examples:

  • ISO 3834
  • EN 1090-2
  • EN 15085
  • ISO 9001
  • PED

Welder qualification standards

In the welding quality management system, the following standards regarding welder qualification and welding procedure specification may apply:

  • ISO 15607
  • ISO 9606

Knowing who should carry out the visual inspection of welding seams to identify any potential welding defects

User testimonials

The VT® gauge principle is GO or NOGO. Measurements, calculations, and manipulation of standards are not involved.

Guy Lardinois SPRL Company

VT© gauges provide significant benefits for welders by reducing training needs. The approach is highly practical and easy to comprehend. The gauges offer excellent value-addition to welding processes. It is a precise and efficient solution.

There's no need to comply with elaborate standards or conduct complex calculations for visual weld quality control. For instance, for craters, visual inspection is now immediately possible without any calculations. The VT© gauge and a flashlight are all that is required to handle any welding situation. By saving an enormous amount of time and ensuring precision, VT© gauges provide a valuable addition to the welder's toolkit. Training requirements are minimized. The approach is highly pragmatic, and it is straightforward to determine the appropriate gauge with the help of available visual aids.

Institut Belge de la Soudure (IBS)

The use of VT© gauges enables visual inspection by non-experts. They are suitable for all types of welding profiles and are cost-effective.

VT© gauges facilitate a visual inspection without requiring an engineering background or extensive consultation of data tables.   This allows for a visual inspection to be conducted in accordance with the welding standard without the need for advanced technical skills.This streamlined inspection process is quick and efficient, eliminating past difficulties with visual inspections. Now, anyone can perform a visual quality control of welds without requiring engineering expertise. It is accessible to individuals across all professions and at an affordable price point.

The new generation of VT© weld inspection gauges is very easy to use and highly accurate. Our trainees show great interest. We use ultra-modern, state-of-the-art equipment

Industry has a chronic shortage of boilermakers and pipe fitters. For boilermaking, the TechnoCampus assembly site is the only training operator to offer short or long courses for the entire Walloon Region. Each instructor at the assemblage site has his or her own complete VT Total kit. Instructors demonstrate the handling of the calibers to trainees and companies, both as part of our teaching and continuing training courses. We also organize information days with the guidance of the IBS (Belgian Welding Institute). We use gauges for all approvals. Thanks to the combination of the new generation VT© gauge and the ultra-simple instruction manual, our instructors can certify to EN 1090-2 very efficiently. The new generation VT© gauge for weld inspection is very easy to use and highly accurate. Our trainees show great interest. We use ultra-modern, state-of-the-art equipment, including welding simulators.
