Issuance of WPQR
CBF (Certification) provides for issuance of
accredited certifications of approval of Welding Procedure Qualification
Records (WPQR). The requested certifications are issued after the
completion of tests in accredited testing laboratories within short
periods of time.
We are capable of performing most of the tests within 2 working days
after the samples are received and results of the tests are communicated
to the clients immediately after the test is completed. Under usual
circumstances reports about the completed tests are sent electronically
within one working day after the test completion.
Do not hesitate to approach CBF (Certification) workers to make sure that your request is fulfilled in time.
The issuance of an inspection certificate for the
Welding Procedure Qualification Record (WPQR) or Welding Procedure
Specification (WPS) is conditional on performance of a number of tests,
such as visual inspection, radiographic testing (RT), ultrasonic testing
or ultrasonic flaw detection (UT or UFD), magnetic particles testing
(MT) and dye penetrant test (PT).
Another part is the application of suitable
mechanical tests, e.g. tensile strength test of a welded joint,
crosswise tensile test, lengthwise bending test, crosswise bending test,
Macroscopic, microscopic test and other assessments.
Overall evaluation of the welded joint is
completed with a macroscopic test, evaluation of hardness, checking of
fracture behavior of a welded joint, impact strength, corrosion
resistance, metal lo graphic test, test of micro structure, determination
of fer rite
quantity - determination of the fer rite number.
ISO 3834-4:2005 (basic level of quality requirements)
- intended for the range of products with basic
safety requirements, which are exposed to average static stress,
products are made of normal materials of known weld ability, mechanical
stability of products is ensured.
