High Intensity Ultraviolet Light

The 400 watt metal halide bulbs or "super light" can be found in some facilities. This super bright will provide adequate lighting over an area of up to ten times that covered by the 100 watt bulb. Due to their high intensity, excessive light reflecting from the surface of a component is a concern. Moving the light a greater distance from the inspection area will generally reduce this glare. Another type of high intensity light available is the micro - discharge light. This particular light produces up to ten times the amount of UV light conventional lights produce. Reading of up to 60,000 uW/cm2 at 15 inches can be achieved.
Determining whether a magnetic field is of adequate strength and in the proper direction is critical when performing magnetic particle testing. As discussed previously, knowing the direction of the field is important because the field should be as close to perpendicular to the defect as possible and no more than 45degrees from normal. Being able to evaluate the field direction and strength is especially important when inspecting with a multidirectional machine, because when the fields are not balanced property, a vector field will be produced that may not detect some defects.
There is actually no easy -to-apply method that permits an exact measurement of field intensity at a given point with in a material. In order to measure the field strength, it is necessary to intercept the flux lines. This is impossible without cutting into the material and cutting the material would immediately change the field within the part. However, cutting a small slot or hole into the material and measuring the leakage field that crosses the air gap with a Gauss meter is probably the best way to get an estimate of the actual field strength within a part. Nevertheless, there are a number of tools and methods available that are used to determine the presence and direction of the field surrounding a component.

Angle beam transducers in ultrasonic testing.

Image
Angle beam transducers   :-Angle beam transducers and wedges are typically used to introduce a refrected shear wave into the test material. Transducer can be purchased in a variety of fixed angles or adjustable versions where the user determines the angles of incidence and refraction. In the fixed angle versions, the angle of refraction that is marked on the transducer is only accurate for a particular material,, which is usually steel. The angled sound path allows the sound beam to be reflected from the Blackwell to improve detectability of flaws in and around welded areas. They are also used to generate surface waves for use in detecting defects on the surface of component. Normal incident shear wave transducer: - are unique because they allow the introduction of shear waves directly into a test piece without the use of an angle beam wedge. Careful design has enabled manufacturing of transducers with minimal longitudinal wave contamination. The ratio of the longitudinal to sh...

Introduction of welding machine,

Introduction of welding machine, The history of welding machines dates back to the 19th century. Here is a brief overview of the development and evolution of welding machines: 1).     Carbon Arc Welding: In the late 1800s, Sir Humphry Davy discovered the process of carbon arc welding. This process involved creating an electric arc between a carbon electrode and the metal to be welded, resulting in the fusion of the metals. 2).     Resistance Welding: In the early 20th century, resistance welding became popular. This technique used electric current and pressure to bond metal parts together. Spot welding, seam welding, and flash welding are common methods of resistance welding. 3).    Arc Welding: The invention of arc welding in the early 20th century brought a major breakthrough in the field. This process involved using an electric arc struck between an electrode and the metal workpiece to create the necessary heat for melting and fusin...
