PAINT DEFECTS

Understanding Grinding Requirements. Mandrels – Quality Defects.

Weld Repairs. 0 “ Welded Body Defects” is one of the most consistent indicators when inspecting for ‘prior repairs’ that could ultimately indicate structural repairs, existing damage or alterations. 0 Use this guide to better understand the various weld ed body defects..

Correcting Welded Conditions. 3. ⋆ Corrective processes involving refinishing the Mandrels: ⋆ Check thickness of buckshots inside the Mandrels before starting ⋆ Check thickness of buckshots after correctio n. ⋆ If more than 0.3- 0.5* mil of weld buckshots i nside the pipe, knockout the buckshot using sanding equipment. ⋆ Use the air blower to blow out the dirt after grinding process. ⋆ Use flashlight to inspect the parts..
