17 MAGNETIC TESTING Specimen #1 The Iron Powder is poured on top of the areas that were welded. For Specimen #1, there was a fillet weld and butt weld. After the Iron Powder is poured on the specimen, the Contour Probe is put on top of the specimen. Afterwards, the Contour Probe is turned on. The Contour Probe applies continuous fields to produce magnetic field to detect cracks in Specimen #1. Based on the test, the Iron Powder follows the line where the pipe was fillet welded to the flat plate. Also, the Iron Powder is on the line where the butt weld was done to connect two smaller flat plates.
