  Painting Inspection, Adhesion Test, QC Training, QC Course X Cut Test (This Document) Cross Cut Tape Test Method A  – X Cut Tape Test An X-Cut is made on the Dry Paint until the bare substrate , a pressure sensitive adhesion tape is applied over  the X cut and removed , the adhesion test is assessed between a scale of 0 to 5 . Instruments used: Sharp Razor Blade / Knife (The cutting edge to be in a good condition, Cutting Guide -Any scale to guide the knife to make straight cut Brush to clean after cut Adhesion Tape- Semi Transparent of Width 25mm or 1 inch. Rubber Eraser – on end of the pencil Torch Light or Lamp Test Procedure: Select an clean and defect free area for test (note: do not carry out test in extreme humidity and temperature) Make Two cross cuts of 40mm length with intersecting angle of 30 to 45 ° and the line should intersect in the middle, refer the image above , Use a torch light/ lamp to ensure that the cut has penetrated until the metal substrate, if ...

Here are some rarely used  NDT – Few Other Methods 1.   Eddy Current Testing – ET: Eddy-current inspection uses  electromagnetic induction  to detect flaws in  conductive  materials. A circular coil carrying current is placed in proximity to the test specimen (electrically conductive). The alternating current in the coil generates changing magnetic field which interacts with test specimen and generates eddy current. The  term eddy current  (also called Foucault currents) comes from analogous currents seen in   water  where localized areas of turbulence  known as eddies  give rise to persistent vortices. When alternating current is applied to the conductor, such as copper wire, a magnetic field develops in and around the conductor. Variations in the electrical conductivity or magnetic permeability of the test object, or the presence of any flaws, will cause a change in eddy current. A corresponding change in the phase ...

  Non destructive Testing (NDT)- Common Methods are: Visual Inspection – VT Liquid Penetrant Testing – LT Magnetic Particle Testing – MT Radiographic Testing – RT Ultrasonic Testing – UT 1.   Visual Inspection – VT: Visual inspection after welding is very useful in evaluating quality, even if other testing methods are to be employed. As welding progresses, surface flaws such as cracks, porosity, and unfilled craters can be detected only by Visual Inspections, leading to repairs or rejection of the work. Welds must be cleaned from slag to make inspection for surface flaws possible. A  10x magnifying glass  is helpful in detecting fine cracks and other faults. As indicated before, a  borescope and dental mirrors , are useful for inspection inside vessels, pipe, or confined areas. Visual inspection  is the most popular and the most widely used of the non-destructive inspection techniques. Completed welds should be checked according to the plans and the sp...
