There is a close relationship between surface preparation and inspection accuracy. Unless surface preparation is done in accordance with the inspection method and the degree of staining, it will be difficult to obtain reliable inspection results. The Non-Destructive Inspection Company has developed various surface preparation methods in aiming to maintain and improve inspection accuracy in the actual inspections of products.
∗Soft Blast (Patent pending)
(1) With the use of low hardness blast cleaning material, stains, rust, or scale may be removed without harming the target item.
(2) Safe thanks to low pressure (∼5 kg/cm2 ),
(3) Both dry and wet types may be used.
(4) With only a small amount of industrial waste produced, it is environment-friendly.
(5) Other work can be conducted in the surrounding area.
