CRC Weld Check System
CRC introduced its new Weld Check System, a 3-step system to detect weld defects quickly and without the use of expensive equipment.
Many cracks in engineering materials can be deep, in spite of having a very small opening width on the surface, and can cause very serious defects. CRC’s 3-step Weld Check System is an extension of the visual inspection method and will clearly show these defects in a few minutes.
Clean Weld Surface: Weld Check Weld Cleaner & Penetrant Remover easily removes dirt and contaminants from surface to be analyzed and will remove the penetrant and developer post-inspection to restore the metal back to its original condition.
Apply Penetrant: Weld Check Penetrant is a red colored liquid penetrant for the non-destructive testing of surfaces and structures. It easily penetrates tiny openings. You can remove excess penetrant with a cloth dampened with Weld Check Cleaner & Penetrant Remover (Do not spray directly on weld.)
Apply Developer: Leave Weld Check Developer on surface for 5 to 15 minutes. This process clearly shows defects which will appear red in color.
This quick, economical process takes only minutes but will detect cracks, lack of fusion and open cavities in welded parts, cracks and cavities caused by metal fatigue and cutting operations, porosity or leaks in pipes, tanks, boilers and heat exchangers, discontinuities, laps, folds and cracks in castings, forgings and ceramics.
