You design, construct or operate tunnels, bridges, viaducts, walkways, historic monuments, etc.  There are many requirements resulting from architectural choices, materials used, regulations, and construction times.  You are continuously looking for solutions and services to assist you and to guarantee that your project will be successful and to assure that the structure can be operated safely.

Institut de Soudure can assist you throughout your project by providing specific solutions to your needs at all stages of a project.

  • Studies - Design

  • Manufacturing

  • Maintenance

  • Training - Certification

​We will assist you in defining components of your structure by verifying your design notes, modelling your structures and checking your welding books...

Our technological Assembly, Mechanics – Corrosion platforms are available to help you define the most suitable welding process for your needs and evaluate the resistance of elements to fatigue and corrosion.

Our teams perform external inspections of new bridges and tunnels independently of applicators.  They work in the manufacturing workshop during dry-run assemblies and during the final assembly on site.

Our internally authorised teams examine the corrosion-resistant coating:

 validation of specifications,

suitability test,

monitoring of application parameters,

tests on dry film,

salt spray test, etc.

Our references include documentation booklets No. 56 and 66 and the steel structures construction standard EN 1090.  Our teams are internally authorised to carry out these missions.  Our inspectors are ACQPA / FROSIO certified for corrosion-resistant protection work using coatings.

​We offer you our experience for in-service monitoring of bridges and tunnels using the most appropriate inspection methods.  Our Cofrend (French Committee for Non Destructive Testing) certified inspectors work with ropes if necessary.

Our experts will help you determine the causes of a failure and advise you about rehabilitation of an old structure including necessary non destructive tests, advice for welded repairs.

​We can assist you in improving the skills of your welders and NDT personnel.  We provide training courses on the design and fabrication of welded structures for your engineers and technicians, and particularly on writing welding procedures and welding books.
