Thermomechanical case- As part of the EPR2 project, EDF wishes to carry out non-destructive volume inspections of enclosure liner welds via UT technologies and wishes to be able to justify the size of certain defects detected. The performance will take place according to the following steps:

■ Mechanical characterization of base and filler metals

■ Manufacture, welding and coupon controls

■ Destructive testing

The service is broken down into a firm part:

SUMMARY OF TESTS

MECHANICAL CHARACTERIZATION OF BASE AND FILLER METALS

MANUFACTURE, WELDING AND INSPECTION OF SPECIMENS

DESTRUCTIVE TESTING

and an optional part: Complementary Tests

The minimum skills required for this service are:

■ Welders must be qualified in accordance with EN ISO 9606-1 and
