When should visual inspection of welds be performed?
Whenever a welding quality management system is required, 100% of welds must undergo a visual testing.
Who can perform visual testing?
In production, the welder is usually the inspector.
What types of geometric imperfections can occur in seam weld ?
Defects are defined and classified in accordance with EN ISO 6520-1.
What are the acceptance criteria for welding defects?
It depends on the quality standard being applied.
How to perform visual inspection of welds?
Disadvantages of conventional measuring tools
Conventional measuring tools require a five-step inspection process.

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.
TECHNOcampus
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.
