What is the difference of a R-Stamp and U-Stamp Certified Welder?

R-Stamp—Boiler repair in the United States is governed by the National Board of Boiler and Pressure Vessel Inspectors and the ASME under a classification called R-Stamp Welding. In order to perform R- Stamp welds and repairs, boilermakers are tested and certified in the quality of their weld joints through a rigorous testing procedure. R stamps are issued to companies that have existing ASME code stamps issued for construction and whose Quality Control system covers repairs or follow the guidelines set up by ASME to obtain a R-stamp. Welders identify their welds by stamping their identifying welder number adjacent to their completed weld with a set of steel stencils.

U-Stamp—the ASME "U" stamp is evidence and certification of an unfired pressure vessel built to Section VIII of the ASME Code. This means that a pressure vessel was specified, designed, fabricated, inspected and tested in accordance with this code. A plate with an ASME vessel number is attached to the component. An independent inspector must certify each and every vessel.
