Engineering Consulting

We are there from the beginning! Already during the engineering we are at your side to advise you.

We review the customer contract, drawings and designs with regard to weldability, testing and corrosion protection feasibility. We also make sure that the technical documentation, the inspection and test plans (ITP) are aligned with the contractual, normative and legal requirements. In addition, we advise you on optimized production technology, material selection, design and finding solutions to production problems.

We offer a wide range of consulting services which include the combination of practical experience, the recognized rules of technology and the methods of the management system.

External Audits & Supplier Qualification

Before placing an order to a supplier, we assess the potential of the supplier so that you know in advance whether the supplier meets the necessary requirements and can achieve the desired quality.

Your supply chain should continue to be solid and resilient. We review management systems according to: ISO 9001 Quality Management, EN ISO 3834 1-4 Quality Requirements Fusion Welding, ISO 14001 Environmental Management and OHSAS 18001 Occupational Health and Safety.

We support suppliers and manufacturers in their integrity to customers, the implementation of their own quality management system and the pursuit of improvement.

Inspections & Documentation

We are fast, flexible, effective and fully tailored to the individual needs of our customers. As your “eyes” and “ears”, we reduce potential risks such as non- compliance with contractual requirements, production fluctuations on site, inferior production and material quality, and delays in production and deliveries.

We identify errors, monitor all necessary on-site corrective actions, and clean up the quality documentation accordingly. We support and moderate your suppliers in the preparation of the quality documentation and the CE certificate of conformity, so that the desired quality is available in time.

Co Values has gained its reputation for reliability, speed, and flexibility to meet and exceed our customers’ needs at all times:

  • Supplier audits / supplier qualifications
  • Testing, monitoring and evaluation of components
  • Monitoring and supervision of welding activities, non destructive testing (UT / RT / PT / MT / VT) and corrosion protection applications
  • Expert reports and claims

Failure Analysis

Our failure analysis offers you factual and independent reporting. This guarantees that you stay informed about the condition of your components including possible causes of damage, and that rectification costs are readily available. Co Values helps you mitigate the resulting financial losses by developing and implementing timely measures. When implementing these measures, we closely monitor the actions and ensure that the documentation is in order.
