CASTING INSPECTION

-Casting inspection is use to check the qulity of casting for Acceptance/Rejection.
-There Are maily two methods of Insopection, (1) Destructive Inspection Method (2) Non Destructive Inspection Method

Destructive Inspection Method

– In Destructive Inspection Method the sample piece of casting is destroyed during Inspection so its known as destructive Inspection Method.
-This inspection is perform on testbar or on Piece-cut from sample casting.
-Inspection is carried out to test and measure mechanical properties like Tensile Strength, Elongation Percentage, Hardness etc.

Non-Destructive Inspection Method

– Inspection is done without distroying the casting.
-A) Visual Inspection : Cracks, Tears dirt, blow holes etc.
-B) Dimensional Inspection : Different gauges and inspection. Techniques are used for dimesional veriification.
-C) Pressure Testing : To locates leaks in casting or check overall strength under hydraulic pressure.
-D) Rediographic Inspection : X-rays are passed through for internal inspection and recodrd on photographic film.
-E) Ultra Sonic Inspection
-F) Flourscent penetration : Dipping, Spraying, white powder, applied.
