External welding supervision
The quality management systems in the field of welding fabrication (ISO 3834, EN 1090, EN 15085 etc.) require the involvement of a welding supervisor. This person must have welding-specific expertise and, depending on the requirements, also be qualified as a Welding Practitioner (IWP), Welding Specialist (IWS), Welding Technologist (IWT) or Welding Engineer (IWE).
These persons assume the main responsibility for the welding quality in the company. At your request and to promote the skills and responsibility of your welding staff at work, LISTEC offers across-the-board support for your staff. Our engineers and specialists have been taking on these tasks for numerous companies in Switzerland and abroad for years.
