  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 ...

   Forging is a manufacturing process involving the   shaping of metal  using localized   compressive forces . Forging is often classified according to the temperature:   “cold”, “warm”, or “hot” forging.   Forged parts can range in weight from less than a kilogram to 580 metric tons. Forged parts usually require further processing to achieve a finished part. Some metals may be  forged cold , but  iron and steel  are almost always  hot forged . Hot forging prevents the work hardening that would result from cold forging, which would increase the  difficulty of performing secondary machining operations on the piece.   While work hardening may be desirable in some circumstances, other methods of hardening the  piece, such as heat treating, are generally more economical and more controllable. Alloys that are amenable to precipitation hardening, such as most aluminium alloys and titanium, can be hot forged, followed by har...

  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...

  What is a cast iron? Cast iron are ferrous alloys with greater than 2% carbon. They also contain small amounts of other materials such as silicon, sulphur, manganese, & phosphorous. In general it consists alloys of carbon & iron. They are the least expensive of all metals and is found plentiful resource than next to aluminium. What makes cast iron an important material? It is a cheap metallurgical substance. Good mechanical rigidity and good strength under compression. Easy castablility. Good machinability can be achieved when a suitable composition is selected. Composition : Carbon – 3.0 to 4.0% Silicon – 1.0 to 3.0% Manganese – 0.5 to 1.0% Sulphur – upto 0.1% Phosphorus – upto 1.0% Influence of cooling rate on the properties :   Types : Grey (General purpose) White (Hard & Wear resistant) Malleable (Heat treated for ductility) Spheroidal Graphite (Some ductility) Grey Cast Iron: It is the least expensive & the most common type of cast iron. It is an alloy o...
