GUIDELINES FOR EVALUATING THE QUALITY OF BOILER TUBE BUTT WELDS WITH ULTRASONIC TESTING

• This Technical Information Paper provides guidelines for testing the quality of boiler tube butt welds using an ultrasonic shear wave testing method. This UT method is an alternative to more traditional, radiographic testing (RT).
• This method can be applied to butt welds in boiler tubes of any material commonly used in power and recovery boilers in pulp and paper mills.
• Procedures and requirements are described to properly qualify the equipment and personnel to affect this type of UT.

It Provides information on:

• Why the UT method should be considered.
  • Practical considerations
  • Recommended practices
• Test and calibration standards.
• Equipment.
• Surface preparation.
• Personnel requirements.

Who will benefit:

• Laboratory Personal.
• Researchers.
• Quality Manager.
• Maintenance Officer.
