Tube to Header Weld Cracking – HRSG Claw

Tube to Header Weld Cracking – HRSG Claw

TesTex adapted the Balanced Field Electromagnetic Technique (BFET) to detect tube to header weld cracking in HRSG units. BFET sensors and cameras are placed on the welds using a C-clamp housing called “The Claw” that attaches to the tube. Once attached to the tube, the Claw moves circumferentially around the weld to detect cracking, lack of fusion, porosity and other defects. The Claw can be customized to inspect 1.5″ – 3.0″ diameters.
