R-Stamp Repair Process
Trap Energy Solutions provides on-site R-stamp welded repairs on all kinds of steam boilers, hot water boilers, and other auxiliary equipment as needed. Here are the steps involved:





Step one
Our certified welders first thoroughly inspect a damaged area or other task using various methods. Techniques such as dye penetrant testing, ultrasonic testing, and radiography can be employed to accurately evaluate the extent of the damage. These inspections help to identify any underlying issues and ensure a comprehensive understanding of the condition of the material or structure.
Step two
The next step in the repair process involves thoroughly cleaning and prepping the area that requires attention. This includes removing any compromised materials through grinding or cutting. Proper preparation is essential to ensure a successful and durable repair.
Step three
Our skilled professionals then execute the repair or task welds, following specific procedures outlined by the ASME code to ensure safety and quality.
Step Four
Post-weld inspection is a critical process that employs nondestructive testing (NDT) methods, such as radiography and magnetic particle inspection, to assess the quality of welded joints. These techniques detect potential defects or discontinuities in the welds without damaging the material.
Step Five
We also provide comprehensive documentation that includes the qualifications of the welder, results from inspections, and the application of the R-Stamp mark to the vessel. This ensures a thorough understanding of the work completed and verifies compliance with industry standards.
