WELD CRACK DETECTION KITS & SPRAY

How does a weld crack detection system work?

1. Clean the surface of the material with cleaner and wipe thoroughly with with a lint free cloth to remove surface contamination. Parts must be at an ambient temperature, before penetrant is applied. Spray the area liberally with the penetrant and allow 10 minutes contact time. If very fine defects are to be located, extend the contact time to 20 minutes.

2. Clean off the penetrant by wiping with a lint free cloth. Complete the removal using a lint free cloth soaked in cleaner. Clean & dry thoroughly.

3. Apply developer by spraying on an even film at least 10 minutes before inspecting for fine defects. Inspect in daylight or under ultra voilet light as appropriate. The system will show continous lines or pin points where there are cracks or porosity.
